Description

MECHANISM AND DEVICES FOR PLAYING GUITAR

This invention relates to the mechanisms for devices which aid in playing the guitar and related devices which help playing the guitar. A guitar is an instrument which operates on the principle that different sounds are produced when strings, having different lengths and thicknesses, are plucked. In addition to the sound box which enables the sound to be amplified, it comprises a fretboard and six strings stretched along the fretboard. The lower strings produce higher notes than the upper ones, at the holding position of the guitar when being played. On the fretboard, there are transverse bars called frets. When pressed down, the strings contact the frets and upon being plucked, only that part of the string extending after the fret vibrates and produces a sound. Hence, the string is shortened so as to produce a higher (sharper) pitch. The shorter and the thinner the strings are, the higher the pitches they produce.

Frets of the guitar are equally spaced on the fretboard. Once the strings are tuned, each fret results in a half-step higher note. The strings of the guitar should be plucked with the right hand while the strings are pressed against the fretboard with the fingers of left hand. The fingers should press between the frets rather than right on the frets themselves.

There are twelve notes in music. These are C- C# (this symbol is named as a sharp and raises the pitch of a note by a semitone. A half-step higher note of a note with a sharp is the next note.)- D- D# - E ( does not have a sharp) - F- F# - G- G# - A- A# -

B (does not have a sharp, either), respectively. After the note B, a higher octave starts with a sharper C, the other notes following in the same order.

These notes are arranged on the guitar as follows: The uppermost string produces an E sound, when not pressed down, i.e. open. When pressed on the first fret an F note is produced, whereas an F# sound is produced when pressed down on the second fret.

As explained above, respective frets produce the respective notes. The uppermost string again produces an E sound when pressed down at the twelfth string.

The strings are arranged such that, E-A-D-G-B-E pitches are produced upon plucking of the open strings, from the top to the bottom. As can be deduced from this, the fifth fret of the sixth string yields the open sound of the fifth string, when counted from the bottom. Similarly, the fifth fret of every string yields the open sound of the lower next string, except the third string. In order to receive from the third string the open sound of the second string, the fourth fret should be pressed on. In order to accompany with the guitar while chanting, chords, which are combinations of notes, should be played rather than playing individual notes. There are mainly twenty-four chords used to compose songs. These, actually, correspond to playing the twelve notes in two different scales, namely the "major" scale and the "minor" scale.

Major and minor scales may easily be explained on the basis of a chord. Every chord consists of three pitches: These are, the note giving the chord its name, the note which is its fourth note on the minor scale and fifth note on the major scale, and its eighth note. To illustrate, The E major comprises the following sounds: First E, then the fifth note (E- F - F# - G- G#) G#, and finally the B note, which is reached by raising three more notes ( A- A# - B). In order to obtain the minor scale from the E chord, it suffices to lower the G# note by a half-step ending up at G.

If we are to locate these notes on the guitar, the following is obtained: For instance, for E minor, no frets are to be pressed on at the sixth string, while it already yields the E note when plucked open. The B note is received by pressing on the second fret at the fifth string. The second fret at the fourth string again produces the E note. The third string is not required to be pressed while it yields G when struck open. The second string yields, correctly, the B note when plucked open. The first string should also be plucked open while in this case it produces an E. To summarise, in order to play the E minor chord, it suffices to press down on the second frets of the fifth and fourth strings and pluck all strings with the right hand. To be able to get the E major chord, pressing on the first fret of the third string is the only thing to be done and consequently the G# note is received. If the example is to be elaborated for the F and G# chords, for all the strings, it is required to press the first next fret for F, and the fourth next fret for G#. More explicitly, the open strings of E should be bridged at the fourth fret so as to receive the G# chord.

For the A chord, rather than halving each string a pitch, the sixth and fifth strings should be left open for producing E and A notes, respectively, and the second fret should be pressed on at the fourth and third strings so as to get E and A notes again. At the second string, the first fret should be pressed on for the minor scale and the second fret should be pressed for the major scale, yielding C and C# sounds respectively. Finally, the first string should be left open to yield an E sound. While retaining the relative positions of the fingers, all the strings are slid by one fret (such that the open strings are pressed on the first fret), A# chord is generated. Similarly, all chords can be played by sliding. As a result, even though various movements are known for every chord of the guitar, by way of pressing two (or four, depending on the minor or the major scale) frets and sliding, other chords can be generated, as illustrated above.

^" Making use of said sliding methods, the mechanism arid the devices subject to the present invention enable the chords to be pressed correctly and the correct sounds to be played when all strings are plucked with the right hand. Thereby, a person who does not know how to play the guitar and completely ignorant of the musical notation, may, with the left hand, press one of these devices on the fretboard so as to get the correct chord position and hence play the guitar. The mechanism developed by the present invention is intended to be applied to the devices which enables the chords to be played by being slid on the fretboard.

Thereby, a person who does not know how to play the guitar and completely ignorant of the musical notation, may, with the left hand, press one of these devices on the fretboard so as to get the correct chord position and hence play the guitar.

No parts of the device for playing guitar involving no movable parts (1.0) are movable. This device (1.0) comprises a part placed on the upper side of the fretboard

(1.1), a part placed on the lower side^' of the fretboard (1.2), a bridge protrusion (1.3), a balance protrusion (1.4), a major pressing piece (1.5), and a connection part of the major scale pressing piece (1.6). The bridge protrusion (1.3) and the major pressing piece (1.5) are the two parts to press between the frets. The major pressing piece (1.5) is at a higher position than the bridge protrusion (1.3) and the balance protrusion (1.4). Hence, its length is shorter. When the device (1.0)_. is placed parallel on the guitar, the major pressing piece (1.5) does not lean on the strings.

The part of the device (1.0) placed on the upper side of the fretboard (1.1) and the part placed on the lower side of the fretboard is placed on the fretboard of the guitar so as to grasp the fretboard from the uppper and the lower sides. Hence, the device is ready for use. In order to successfully use on the guitar the device for playing guitar involving no movable parts (1.0), the fourth and fifth strings from the bottom, should be retuned to two higher pitches. In this way, when all strings are plucked open, the strings would reveal E B E G B E notes, from top to the bottom, which correspond to the E minor chord. For the E major chord, it suffices to press on only the first fret of the third string. There are two pressing positions of the device for playing guitar involving no movable parts (1.0): The first one is, pressing the device parallel against the fretboard. In this position, the bridge protrusion (1.3) and the balance protrusion (1.4) presses on between the frets and the minor chords of all notes can be played. The sole function of the balance protrusion (1.4) is to provide a balanced pressing of the device (1.0) on the strings. Except the bridge protrusion (1.3) which contact all the strings and the balance protrusion (1.4) which supports it, no part of the device (1.0) contacts the strings of the guitar. The two other pieces (1.1 and 1.2) neighbouring the contacting parts (1.3 and 1.4), enable assembling on the upper and lower sides of the fretboard. While the major pressing piece (1.5) is at a higher position than the bridge protrusion (1.3) the balance protrusion (1.4) (i.e. it is shorter) when the device (1.0) is placed parallel on the guitar, the major pressing piece (1.5) does not lean on the strings.

In the second pressing position of the device for playing guitar involving no movable parts (1.0), the device (1.0) is placed on the guitar with an angle (sloping forwards) such that the major pressing piece (1.5) presses on the third string from the bottom. In this case;

• The bridge protrusion (1.3) presses on all strings,

• The major pressing piece (1.5) presses on the third string from the bottom, • The balance protrusion (1.4) is spaced from the strings (does not press on any string),

Hence, by way of pressing on the third string the major pressing piece (1.5) turns the chord being played into a major chord. Positioning the major pressing piece (1.5) such that its part to press the third string is right on the third string is not problematic from the point of the player since the fretboard is already firmly fitted between the upper and the lower parts (1.1 and 1.2).

Even though the device for playing guitar involving no movable parts (1.0) is useful, it is rather slow and not functional as desired, when, for instance, a D chord is to be played right after an F chord, necessitating a slid of nine frets. Moreover, as mentioned above, the tuning of guitar has to be changed. In order to solve the problems of the device for playing guitar involving no movable parts (1.0), the device for playing guitar involving a single movable part (2.0) has been developed.

The device for playing guitar involving a single movable part (2.0) comprises a part placed on the upper side of the fretboard (2.1), a part placed on the lower side of the fretboard (2.2), a bridge protrusion (2.3), a balance protrusion (2.4), a major-minor movable part (2.5), a finger ring (2.6) and a support rod (2.7).

The body of the major-minor movable part (2.5) comprises a semi-round shaped part (2.10), one side (2.12) of which does not press on the guitar strings and the other side of which presses on the first fret starting from the bridge protrusion (2.3), and a protrusion (2.11) extending from the semi-round shaped part (2.10) and pressing on the second fret starting from the bridge protrusion (2.3). formed piece

The major-minor movable part (2.5) comprises,

• a part connecting the finger ring to the major-minor movable part (2.8),

• fixing rods for the major-minor movable part (2.9), • a first pressing point of the major-minor movable part (2.10),

• a second pressing point of the major-minor movable part (2.11), and • a no-contact point of the major-minor movable part with the string (2.12).

When the finger ring (2.6) is pulled upwards reaching its uppermost position, the part connecting the finger ring to the major-minor movable part (2.8) forces the major- minor movable part (2.5)^" to take its first position, at which, the major-minor movable part (2.8) does not contact the guitar strings due to the fact that the no-contact point of the major-minor movable part with the string (2.12) is in function.

When the finger ring (2.6) is slightly pushed downwards reaching its middle position, the part connecting the finger ring to the major-minor movable part (2.8) forces the major-minor movable part (2.5) to take its second position, at which, the first pressing point of the major-minor movable part (2.10) presses on the first fret starting from the bridge protrusion (2.10).

When the finger ring (2.6) is fully pushed downwards reaching its lowermost position, the part connecting the finger ring to the major-minor movable part (2.8) forces the major-minor movable part (2.5) to take its third position, at which, the second pressing point of the major-minor movable part (2.11) presses on the strings of the guitar (second fret starting from the bridge protrusion (2.10)) right next to the balance protrusion (2.10).

It is not necessary to change the notes of the strings (tuning of the guitar) to be able to employ the device for playing guitar involving a single movable part (2.0). The device for playing guitar involving a single movable part (2.0) is placed on the upper part of the fretboard such that the fretboard is inserted between the part placed on the upper side of the fretboard (2.1) and the part placed on the lower side of the fretboard (2.2). The opening (distance) between the the part placed on the upper side of the fretboard (2.1) and the part placed on the lower side of the fretboard (2.2) of the device for playing guitar involving a single movable part (2.0) is greater (larger) than the width of the fretboard of the guitar. Hence the device (2.0) can be moved up and down.

When the fretboard of the guitar leans against the part placed on the lower side of the fretboard (2.2) minor chords are generated at the first position and major chords are generated at the second position; on the other hand, when the fretboard of the guitar leans against the part placed on the upper side of the fretboard (2.1) minor chords are generated at the second position and major chords are generated at the third position.

The finger ring (2.6), which is worn on the finger, is the sole movable part of the device for playing guitar involving a single movable part (2.0). When the finger is at its top position and the fretboard of the guitar is leaned against the part placed on the lower side of the fretboard (2.2), if the bridge protrusion (2.3) is on the fifth string, a minor chord is generated. If the finger moving the finger ring (2.6) is at the middle position, then the chord is A major. The reason for this being, the finger ring's (2.6) pressing on no fret at the finger's top position, first fret at the finger's middle position and second fret at the finger's bottom position. When the fretboard of the guitar is leaned against the part placed on the upper side of the fretboard (2.1), D minor and D major chords are received, if the finger, and consequently the finger ring (2.6) through which it passes, is at middle and bottom positions, respectively.

In order to play a D chord right after an F chord while employing the device for playing guitar involving a single movable part (2.0), it suffices to slide the device by four frets only. Therefore, the device for playing guitar involving a single movable part (2.0) is more functional as compared to the device for playing guitar involving no movable parts

(1.0).

Despite the above, in case the finger ring (2.6) is at its bottom position when the fretboard rests against the part placed on the lower side of the fretboard (2.2) and at its top position when the fretboard rests against the part placed on the upper side of the fretboard (2.1), wrong sounds are generated which are not chords. Moreover, when moving the device (2.0) up-down and right-left on the fretboard, it is highly difficult to retain the correct position finger in the finger ring (2.6). In addition, having allocated one finger for said duty, it is quite difficult with the remaining three fingers to sufficently press the device (2.0) against the fretboard so as to produce a pure sound.

In order to solve the problems related to the device for playing guitar involving a single movable part (2.0), the device for playing guitar involving two movable parts (3.0) has been developed. The device for playing guitar involving two movable parts (3.0) comprises a part placed on the upper side of the fretboard (3.1), a part placed on the lower side of the fretboard (3.2), a bridge protrusion (3.3), a balance protrusion (3.4), a first major-minor movable part (3.5), a second major-minor movable part (3.6) and springs of major-minor movable parts (3.7).

The opening (distance) between the the part placed on the upper side of the fretboard (3.1 ) and the part placed on the lower side of the fretboard (3.2) of the device for playing guitar involving two movable parts (3.0) is greater (larger) than the width of the fretboard of the guitar allowing thereby the device (3.0) to be moved up and down. Thanks to the springs (3.7), the first major-minor movable part (3.5) and the second major-minor movable part (3.6) stay at a higher position so as not to contact the strings when force is not exerted on them, press on the string when force is exerted, and returns to its first position when the force is removed.

The device for playing guitar involving two movable parts (3.0) comprises first and second nϊajor-minor movable part (3.5 and 3.6) which can move independently. The parts of these pieces (3.5 and 3.6) which protrude from the top of device (3.0), are in the form of buttons to be pressed by fingers. These buttons should be pressed with the middle finger and the ring finger. However, when pressing the parts of the fingers on which rings are worn (the third part from the tip) are employed rather than their tips. By pressing on the device (3.0) with the forefinger and the small finger such that the fingers are always straight (not bent), the position of the device (3.0) is fixed on the fretboard of the guitar. The other two fingers (middle finger and the ring finger), on the other hand, exert force on the buttons (3.5 and 3.6) in a straight position when required, whereas in a bent position (such that the tip of the finger contacts the device) at other times, thereby eliminating excess power loss and simultaneously retaining the buttons (3.5 and 3.6) at their non-pressed positions under the bent fingers.

When the part (3.2) of the device (3.0) that is placed on the lower side of the fretboard rests on the lower side of fretboard of the guitar;

• minor chords are obtained when the first and second major-minor movable parts (3.5 and 3.6) are not pressed on, and • major chords are obtained when the first major-minor movable part (3.5) is pressed on.

When the part (3.1) of the device (3.0) that is placed on the upper side of the fretboard rests on the upper side of the fretboard of the guitar;

• minor chords are obtained when the first major-minor movable part (3.5) is pressed on, and

• major chords are obtained when the second major-minor movable part (3.6) is pressed on.

The problems related to this device (3.0) are as follows:

• None of the buttons can be pressed when the part (3.1) of the device (3.0) that is placed on the upper side of the fretboard rests on the upper side of the fretboard of the guitar; • Upon pressing the second major-minor movable part (3.6), wrong sounds are produced, which are not chords, in case the part (3.2) of the device (3.0) that is placed on the lower side of the fretboard rests on the lower side of fretboard of the guitar. Moreover, under the condition that the first major-minor movable part (3.5) is pressed on, a major chord is obtained when the part (3.2) of the device (3.0) that is placed on the lower side of the fretboard rests on the lower side of fretboard of the guitar, whereas a minor chord is obtained when the part (3.1) of the device (3.0) that is placed on the upper side of the fretboard rests on the upper side of the fretboard of the guitar, which is confusing for those who master playing the guitar.

In order to solve the problems related to the device for playing guitar involving two movable parts (3.0), the device for playing guitar involving three movable parts (4.0) has been developed. The device for playing guitar involving three movable parts (4.0) comprises a rod placed on the upper side of the fretboard (4.1), another rod placed on the lower side of the fretboard (4.2), a bridge protrusion (4.3), a balance protrusion (4.4), a first major-minor movable part (4.5), a second major-minor movable part (4.6), a button common to the first and second major-minor movable parts (4.7), a connection spring of the button common to the first and second major-minor movable parts (4.8), a Z formed piece (4.9), a three-holed side surface (4.13), a major-minor indication part (4.17), and a lower-upper position indicator connected to the rod placed on the upper side of the fretboard of the guitar (4.18).

The Z formed piece (4.9) comprises a third major-minor piece fixed to the Z formed piece (4.10), a hole of the Z formed piece for the passage of the first major-minor movable part (4.11), and a hole of the Z formed piece for the passage of the second major-minor movable part (4.12). The Z formed piece (4.9) is connected at a single point to the body of the device (4.23) via a connection pin (4.20). It can turn clockwise or counterclockwise. In addition, the rod placed on the upper side of the fretboard (4.1) and the other rod placed on the lower side of the fretboard (4.2) are assembled onto the two sides of the Z formed piece (4.9). The three-holed side surface (4.13) comprises, a vision window for observing the respective fret on which the device is placed (4.14), a further vision window for observing the major and minor (4.15), and another vision window for inspecting the lower-upper positions of the device on the fretboard (4.16). The device is equipped with a lower-upper position indicator (4.18) connected to the rod placed on the upper side of the fretboard of the guitar (4.1). During the downwards and upwards movements of the device (4.0) on the guitar fretboard, the lower- upper position indicator (4.18) that is connected to the rod placed on the upper side of the fretboard of the guitar (4.1) opens or covers the vision window for inspecting the lower- upper position (4.16).

The bridge protrusion (4.3) of this device (4.0), is the part which presses on all strings of the guitar on the same fret at the same time. The bridge protrusion (4.3) is a part which extends along the whole length on one side of the body of the device (4.23). On the other side of the body of the device (4.23), there is the balance protrusion (4.4). The balance protrusion (4.4) provides pressing on the two strings at the same, spaced apart from the bridge protrusion (4.3) by two frets.

The device for playing guitar involving three movable parts (4.0), one of the movable parts is the button common to the first and second major-minor movable parts (4.7). A major chord is played when this button (4.7) is pressed whereas a major chord is played when this button (4.7) is not pressed. The button common to the first and second major-minor movable parts (4.7) is fixed on the device (4.0) through the connection spring of the button common to the first and second major-minor movable parts (4.8). On the two sides of the button common to the first and second major-minor movable parts (4.7) there exists the first major-minor movable part (4.5) and the second major-minor movable part (4.6), positioned so as to extend towards the inner part of the device (4.0). The first major-minor movable part (4.5) and the second major-minor movable part (4.6) are connected to the button (4.7) via the springs (4.19). Therefore, as soon as the force is no more exerted, the button (4.7) returns to its initial position. The tips of the first major- minor movable part (4.5) and the second major-minor movable part (4.6) press on the strings.

The major-minor indication wire (4.17) connected to the button common to the first and second major-minor movable parts (4.7), passes through passage recess of the major-minor indication wire (4.22), and extends to inner side of the device (4.0). Attached to its end that is inside of the device (4.0), there is the major-minor indication part (major-minor indicator) (4.21). When the button (4.7) is pushed, the indicator opens or covers the vision window for observing the major and minor (4.15), by moving up or down. The Z formed piece (4.9) inside the device is connected to device (4.0) at a single point (4.20) and is able to move in two directions. The Z formed piece (4.9) closes the hole of the Z formed piece for the passage of the first major-minor movable part (4.11 or

4.12) by rotating in one direction, and closes the other the hole of the Z.formed piece for the passage of the first major-minor movable part (4.12 or 4.11) by rotating in the other direction. When the button (4.7) is pressed, only the first or the second major-minor movable part (4.5 or 4.6) which passes through the open hole contacts the strings. When the Z formed piece (4.9) rotates in the reverse direction, the other hole (4.11 or 4.12) is closed, rendering the front of the other first or the second major-minor movable part (4.5 or 4.6) open and permitting them to press on the string.

There are two holding means connected to the Z formed piece (4.9), the first one being the rod placed on the upper side of the fretboard (4.1) and the second one being the rod placed on the lower side of the fretboard (4.2). The fretboard of the guitar is placed between these two rods (4.1 and 4.2). Consequently, as the device (4.0) moves up and down on the fretboard, the Z formed piece (4.9) rotates as described above, opening one of the holes of the Z formed piece for the passage of the first major-minor movable part (4.11 or 4.12) and closing the other.

On the three-holed side surface (4.13) of the device for playing guitar involving three movable parts (4.0), there exist • the vision window for observing the respective fret on which the device is placed

(4.14) enables seeing through the signs on the fretboard of the guitar;

• the vision window for observing the major and minor (4.15), provides seeing through the major-minor indication part (4.21) which is connected to the major- minor indication part (wire) (4.0) via its end inside the device (4.0); and • the vision window for inspecting the lower-upper positions (4.16) enables observing the lower-upper position indicator (4.18) connected to the rod placed on the upper side of the fretboard of the guitar (4.1).

The vision windows (4.14, 4.15 and 4.16) helps seeing the upper-lower position of the device (4.0) on the fretboard, its position and whether a major or minor chord is pressed. Thereby, the player exactly knows which chord is being played.

There are two usage positions of the device for playing guitar involving three movable parts (4.0): First position: This is the position at which the device rests against the fretboard from the lower side. In this position, the rod placed on the lower side of the fretboard (4.2) leans against the fretboard from the lower side. In this case, the Z formed piece (4.9) rotates to take its first position. In the.said position, the hole of the Z formed piece for the passage of the first major-minor movable part (4.11) corresponds to the first major-minor movable part (4.5), the third major-minor piece fixed to the Z formed piece (4.10) is hindered by the balance protrusion (4.4), and the hole of the Z formed piece for the passage of the second major-minor movable part (4.12) does not correspond to the second major-minor movable part (4.6). Therefore, this part (4.6)_cannot pass through the passage hole on the body of the device (4.23) and upon pressing the button common to the first and second major-minor movable parts (4.7) only the the first major-minor movable part (4.5) passes through the hole of the Z formed piece for the passage of the first major-minor movable part (4.11) and presses on the string turns the chord into a major chord. If the button common to the first and second major-minor movable parts (4.7) is not pressed, a minor chord is played. In this position, the lower-upper position indicator connected to the rod placed on the upper side of the fretboard of the guitar (4.18) covers the vision window for inspecting the lower-upper positions of the device on the fretboard and hence the user easily sees that s/he is at the first position. If the button common to the first and second major-minor movable parts (4.7) is pressed, the major-minor indication wire (4.17) pulls the major-minor indication part- major-minor indicator (4.21) to the front of the vision window for observing the major and minor (4.15) and hence the user easily sees that s/he is playing a major chord.

At the first position, while the bridge protrusion (4.3) is pressing on all strings, the balance protrusion (4.4) presses on the 4^th and 5^th strings, at two further frets. Second position: This is the position at which the device (4.0) rests against the fretboard from the upper side. In this position, the rod placed on the upper side of the fretboard (4.1) leans against the fretboard from the upper side. In this case, the Z formed piece (4.9) rotates to take its second position.

In the said position, the hole of the Z formed piece for the passage of the second major-minor movable part (4.12) corresponds to the second major-minor movable part

(4.6), the third major-minor piece fixed to the Z formed piece (4.10) is not hindered by the balance protrusion (4.4) and is above the major-minor movable part (4.6), and the hole of the Z formed piece for the passage of the first major-minor movable part (4.11) does not correspond to (does not open) the first major-minor movable part (4.5). Therefore, the first major-minor movable part (4.5) cannot pass through the passage hole on the body of the device (4.23) upon pressing the button common to the first and second major-minor movable parts (4.7). However, the second major-minor movable part (4.6) passes through the hole of the Z formed piece for the passage of the second major-minor movable part (4.12) and presses on the third string turning the chord into a major chord. In this position, the lower-upper position indicator (4.18) connected to the rod placed on the upper side of the fretboard of the guitar opens the vision window for inspecting the lower-upper positions of the device on the fretboard (4.16) and hence the user easily sees that s/he is at the second position. If the button common to the first and second major-minor movable parts (4.7) is pressed, the major-minor indication wire (4.17) brings the major-minor indication part- major-minor indicator (4.21) to the front of the vision window for observing the major and minor (4.15) and hence the user easily sees that s/he is playing a major chord.

At the second position, while the bridge protrusion (4.3) is pressing on all strings, the balance protrusion (4.4) presses on the 3^rd and 4^th strings, at two further frets. At both positions, the user reads through the window (4.14) the number of the fret written (imprinted) on the fretboard and easily knows on which fret s/he is.

DETAILED EXPLANATION OF THE MECHANISM

In this invention a guitar playing device mechanism for a guitar having a fretboard with frets and strings, wherein the mechanism is positionable in different positions on the fretboard and wherein the mechanism comprises mechanical elements which press frets and/or strings to obtain different chords correctly has been developed.

The mechanism for the device for playing guitar, developed by the present invention, basically consists of 4 main parts, which are:

• Bridge sliding part, • Line (upper-lower) sliding part,

• Button part

• Indicator part

The bridge sliding part comprises, the camouflage lid of the bridge sliding screw (1), the bridge part (4), the bridge sliding screw (7), the tapeline which rotates the bridge sliding screw (11), and the hook part (17). The tapeline (2) is in the form of a rope, and, thanks to its resiliency, returns to its initial length once the pulling force is removed. The line (upper lower) sliding part comprises the multifunctional L-formed part (5), the main movable part (9), and the lever (13).

The button part comprises the button upper part (6), the button lower part (8), the major-minor indicator^'plate (10), lever support piece (15), and the button connection part of the main movable part (18).

The indicator part comprises, the indicator diagram (2) attached to the upper side of the guitar, the note indication hole part (14), the tapeline (16), and the major-minor indicator plate (10), the end of the multifunctional L-formed part which pushes the note indication hole part (19), and the tapeline connection end (20) of the indicator diagram part which is attached to the upper part of the guitar. The tapeline (16) is in the form of a tape, and, thanks to its resiliency, returns to its initial length once the pulling force is removed.

The bridge indication part basically operates independently of the other parts. However, the other parts, namely the line (upper lower) indication part, the button part, and the indicator part operate together in a co-ordinated manner.

The mechanism for the device for playing guitar, subject to the present invention, has been designed to make a total of 40 types of movements on the fretboard (27), including the two lines (upper and lower) and the 10 columns (left and right).

The mechanism has been designed such that it rearranges itself on every point of chord and consequently adopts to the chord and the guitar.

The hook part (17) of the mechanism of guitar playing device devised by the present invention, is attached on the peg, the part of the guitar onto which the strings are tied and provides tuning the guitar by being rotated, before the device is started to be used. The mechanism is seated on the fretboard such that, the indicator diagram part attached to the upper side of the guitar (2) and the part attached to the under side of the guitar grasp the fretboard from the top and the bottom.

As the mechanism is moved longitudinally to the left and to the right, the tapeline (11) is pulled causing the bridge sliding screw (7) to be rotated and thereby the bridge part (4) to be slid, and hence the area of the mechanism in contact with the guitar is narrowed. Consequently, upon being moved longitudinally on the fretboard towards left and right, the mechanism automatically adjusts itself to the change of the spacing of the frets. While the mechanism is being moved to the left and right, the operation of the parts which adjust the distance among the parts of the mechanism that are contacting the guitar is completely independent from the operation of the parts of the line and button mechanisms. The mechanism is placed on the guitar, such that the fretboard (27) is in between the indicator diagram part (2) attached to the upper side of the guitar and the part attached to the lower side of the guitar, and that the tapeline (11) rotating the bridge sliding screw is close to the pegs of the guitar. As the palm of the left hand of the guitar player grasps the part (3) attached to the lower side of the guitar (26), the four fingers are pressed on the upper part of the mechanism where the button is placed as well, and the thumb presses on the back side of the fretboard, the mechanism is pressed against the fretboard of the guitar. However, it has to be paid attention that, when the guitar player, in a sloped position, presses his/her fingers that s/he placed on the upper side of the mechanism, the button coincides with the space between the first and second joints of the fingers and the button is not pushed. When the mechanisms to be moved upwards and downwards, the mechanism is not pressed against the fretboard anymore and the button is not pushed.

When the mechanism is pressed on the fretboard at the first position (the button is not pushed and it is positioned on the first line), the bridge part (4) and the large part (21) contacts the strings. If we assume that the bridge part (4) is pressed on the first fret, the large part presses on the 5^th and 4^th strings of the 3^rd fret. At this position, if he strings are plucked, F minor chord is obtained. Even though the small part (21) contacts the 2^nd fret of the 4^th string, due to the fact that the large part (21) is placed at a more forward position than the small part (22), the small part (22) pressing on the string does not have an effect on the sound.

When the mechanism is pressed on the fretboard at the second position (the button is pushed and it is positioned on the upper line), the bridge part (4) and the large part (21) contacts the 5^th and the 4^th strings. Since one end of the button lower part (8) (the end closer to the bridge part (4)) is open (free) and the other end is closed, the button lower part (8) bends towards that side, and presses on the 1^st fret of the 3^rd string starting from the hole at the middle of the multifunctional L-formed part (5), in other words the bridge part (4) under the small part (22). Hence, if we assume that the first fret is pressed on, F major chord is obtained. Even though the small part (22) also contacts the string, because the large part ( 21) is placed at a more forward position than the small part (22), the small part (22) pressing on the string does not have any effect on the sound.

At the 3^rd position, the mechanism is slid to the bottom string. This sliding operation is performed ad explained herebelow. Before the sliding operation, the mechanism is pulled downwards without being pressed towards the guitar.

As the guitar player moves his/her hand downwards without pressing the button, the indicator diagram part attached to the upper side of the guitar (2) and the part attached to the lower side of the guitar (3) do not move, resulting in a downward motion of the main movable part (9). Thus, the large part (21) releases the 5^th and the 4^th strings and instead presses on the 4^th and 3^rd strings. During the said sliding operation, since one end of the lever (13) is attached to the indicator diagram part attached to the upper part of the guitar (2), its center is attached to the main movable part (5), and the other end is attached to the multifunctional L-formed piece (5), and since the indicator diagram part (2) attached to the upper side of the guitar does not move, the multifunctional L-formed piece (5), quite naturally, moves by two units as the main movable part (9) moves by one unit, the small part (22) leaves its position at the back of the large part (21) and presses on the 1^st fret of the 2^nd string starting from the bridge part (4) and consequently the chord is sharpened by 5 notes.

When the mechanism is pressed on the fretboard at the third position (the button (6) is not pushed and it is positioned on the bottom line), the bridge part (4) presses on all strings whereas the small part (22) presses on the 2^nd string and the large part (21) presses on the 4^th and the 3^rd strings. For instance, when the bridge part (4) contacts all strings on the first fret, the small part (22) presses on the 2^nd fret and the large part (21) presses on the 3^rd fret. Thus, A# minor chord is produced. When the mechanism is pressed on the fretboard at the fourth position (the button

(6) is pushed and it is positioned on the bottom line), the bridge part (4) presses on all strings whereas the large part (21) presses on the 4^th and the 3^rd strings. Since one end of the button lower part (8) (the end distal to the bridge part (4)) is open (free) and the other end is closed, the button lower part (8) bends towards that side, and presses on the 2^nd fret of the 2^nd string starting from the bridge part (4) under the large part (21) pressing on the string. Simultaneously, the small part (22) presses on the 1^st fret of the 2^nd string, starting from the bridge part (4). However, because it is located behind the button, it does not have an effect on the sound. Hence, if we assume that the first fret is pressed on, A# major chord is obtained when all the strings are plucked. When the mechanism is at the bottom position and the button is not pressed, if the player of the guitar (26) moves the mechanism upwards, it is ended up at the first position.

The operation principle of the button of the mechanism is as follows: The main part is the lower button part (8). The guitar player presses with his/her finger on the button upper part (6) and causes it to push the button lower part (8) and thereby press on the string. Between the main movable part (9) and the button lower part (8), at the lower middle part of the button lower part (8), there is a spring which pushes the button lower part (8) upwards when the button is first pressed then released. Despite the power of the spring, the button lower part (8) does not depart from the mechanism, since it leans on the button connection part of the main movable part (9). There are two ends of the button lower part (8). Only one of these ends is open at every four positions and may press on the string, if desired so. The distance between the points to which the ends of the button lower part (8) contact, is equal to the radius of the circle which is obtained if the button lower part (8) is symmetrically divided through its center into two parts and each part (which are already parts of a circle) is completed to a circle.

The indicator part of the mechanism consists of two independent main indicators. One of them is the major-minor indicator plate (10) which moves inside the indicator diagram part (2) that is attached to upper part of the guitar and is connected to the lever (12) and the button lower part (8); whereas the other is the note sign diagrams which can be seen through the note indication hole part (14) that is moved by the end of the multifunctional L-formed part (19) that pushes the note indication hole part.

The first indicator is the hole (29) on the indicator diagram part (2) which is attached to the upper part of the guitar (2). When the button lower part (8) is moved downwards, its end connected to the button lower part (8) moves downwards together with the button lower part, since its center is connected to the lever support part (15). Simultaneously, while its end connected to the major-minor indicator plate (10) moves upwards, towards whichever direction the button lower part (8) is pressed, the major- minor indicator plate (10) moves downwards upon being pulled upwards and then released. The hole (29) on the indicator diagram part (2) attached to the upper part of the guitar is the first indicator that shows the major-minor indication plate (10) which is the readable part of the lever (12).

There are note signs on the upper edge of the fretboard (27) of the guitar (26). On the other hand, the second indicator is note indication hole part (14) which is the end of the multifunctional L-formed part (5), which hinders one part while displaying the other part of the other hole on the indicator diagram part (2) that is attached to the upper part of the guitar as a result of its motion triggered by the between-the-lines movements of the end (19) of the multifunctional L-formed part pushing the indicator diagram part, and which displays the fret it belongs to on the note indication diagram as the mechanism is moved towards left or right. In order for the second indicator to function, the tapeline is attached in advance to the peg side of the guitar and the player sees the chord s/he is currently playing. The part of the mechanism that is worn on the hand (25) should be fixed to the main movable part (9). Thereby, as one moves his hand upwards or downwards, the main movable part (9) moves on the remaining parts of the mechanism.

The mechanism of the guitar playing device subject to the present invention is designed to be applied to the devices which provides the chords to be pressed by being slid on the fretboard (27) of the guitar (26) and thereby enables a person who does not know how to play the guitar and completely ignorant of the musical notation to press the device involving this mechanism on the fretboard with his/her left-hand, to obtain the correct chords when s/he plucks all the strings with the right hand and hence plays the guitar while seeing the chord s/he has been playing.
