Description

FIELD OF THE INVENTION

The present invention relates to musical instruments, and more particularly to a piano guitar, i.e. a guitar that automatically plays a piece of music performed by a musician on a piano-type keyboard.

State of the art

Currently, various devices are known that allow a musician to play musical pieces on a guitar while playing the piano keyboard.

For example, in the application of the UK No. 2362023 (publ. 07.11.2001) described in General terms such a device. However, the absence of specific embodiments in this description does not allow reproducing this device.

Known string musical instrument with a keyboard type piano, described in US patent No. 5691490 (publ. 25.11.1997). In this device, an electronic keyboard is attached directly to a string instrument such as a guitar with the ability to adjust the location of this keyboard relative to the guitar body. However, this device does not provide the ability to convert chords taken on an electronic keyboard to typically guitar chords.

Disclosure of invention

The purpose of the present invention is to develop such a device, which would have wider than the known counterpart, the possibilities of typically guitar playback of musical works. In particular, it is desirable that such a device would allow playing guitar chords in an optimal manner.

To solve this problem and provide the specified overall technical result, the present invention provides a piano guitar, comprising: an electronic keyboard, designed for the performance of musical works by a musician; an acoustic guitar with an automatic player configured to evoke the sound of acoustic guitar strings when appropriate signals are supplied to it; wherein the storage means of the control unit in the automatic player comprises a program which, when executed in the processor of the automatic player, causes the processor to convert the signals from the electronic keyboard into signals for the automatic player.

To ensure the above particular technical result, the program in the piano guitar in accordance with the present invention in the control unit of the automatic player can, if a musician takes a chord on the electronic keyboard, ensure that this chord is played on an acoustic guitar in the optimal embodiment, when the length of the sounding strings is maximum. At the same time, the program can choose the best option according to a predefined table for converting piano chords into guitar ones.

Brief Description of the Drawings

The invention is explained further using the attached drawings.

In FIG. 1 schematically shows the configuration of the piano guitar of the present invention.

In FIG. 2 shows diagrams explaining the chord playing on a six-string guitar.

Detailed description

A performance guitar is a very complex musical instrument. Only a high-class guitarist can perform a virtuoso guitar melody on a guitar, but a beginner pianist can, in principle, also perform the same melody on a piano (piano). Therefore, the use of the piano guitar of the present invention allows the performance of virtuoso guitar melodies, not necessarily virtuosos.

The piano guitar of the present invention comprises (Fig. 1) a piano type electronic keyboard 1 for performing music by a musician. As such an electronic keyboard, you can use any suitable keyboard, for example, such as disclosed in the aforementioned analogues. However, it is preferable to use the so-called MIDI keyboard (Musical Instrument Digital Interface - digital interface for musical instruments; a standard for digital sound recording on the data exchange format between electronic musical instruments).

Further, the piano guitar of the present invention comprises an acoustic guitar 2, on which an automatic player 3 is mounted, configured to cause the strings of the acoustic guitar 2 to sound when the corresponding signals are supplied to this automatic player 3. As such an automatic player 3 can be used, for example , the device described in US patent No. 6723904 (publ. 04/20/2004), or any other device known or being developed in the future, which, in accordance with the signals supplied to it makes the strings of an acoustic guitar sound 2.

In any automatic player 3 there are means for pressing the strings to various frets of the neck and means for extracting sound from the strings. It will be appreciated by those skilled in the art that these means must be triggered when corresponding signals are supplied to them from a control unit, to the input of which the output of the electronic keyboard 1 is connected. In the present invention, this control unit 4, conventionally shown in FIG. 1 separately from the automatic player 3, contains interconnected processor 5 and a storage means 6 storing a program which, when executed in the processor 5, causes this processor 5 to convert the signals from the electronic keyboard 1 to the signals for the automatic player 3.

In particular, this program, if a musician takes a chord on an electronic keyboard 1, ensures that this chord is played on acoustic guitar 2 in the best case, when the lengths of the sounding strings are maximum.

FIG. 2 illustrates this case. In FIG. Figures 2a and 2b show diagrams of possible string pressing to take the same chord. It can be seen from these diagrams that in the first embodiment (Fig. 2a) the strings are pressed so that their lengths are longer than in the second case (Fig. 2b), although the chord will sound the same in both cases. The optimal options for pressing the strings (so that the length of each string is maximum) are calculated in advance for each chord and are summarized in a list or table. When the musician takes the appropriate chord on the electronic keyboard 1, the signals from the pressed keys are sent to the control unit 4, where they are converted in the processor 5 under the control of the program stored in the storage means 6 into the optimal guitar chord according to a pre-compiled table for converting piano chords to guitar ones. The received signals are fed from the control unit 4 (processor 5) to the corresponding actuators of the automatic player 3, which press the required strings and extract sounds from them.

Thus, the present invention provides a piano guitar having wider possibilities than typical of a known analogue for typical guitar reproduction of musical compositions. In particular, this piano guitar allows you to play guitar chords in an optimal way.
