Definitions

  • the present invention relates to a device with shortening elements for string instruments, in particular guitars, lutes, banjos, kobsen, mandolins or the like.
  • the device with shortening elements is used for "setting chords or tones by means of operating elements which act on the shortening of the strings.
  • Such devices are known and serve to either facilitate or enable playing on the string instruments mentioned.
  • Chords, chord progressions or individual tones on the string instruments mentioned are produced, for example, on the gi-tarre with four fingers and, if appropriate, with the thumb of the so-called gripping hand by shortening the strings that are brought to sound with the playing hand. For example, many chords cannot be grasped on the six strings of the guitar, or only insufficiently, because the four gripping fingers and possibly the thumb ' cannot grip all possible chords correctly.
  • the game aid known from DE-OS 19 40 660 also takes up most of the neck and contains a large number of keys and struts with which the strings are shortened, the pressure on the keys corresponding to the pressure on the shortening elements.
  • the tuning of the guitar is changed from normal tuning to C, small octave - G, small octave - es - g - c - es.
  • a device known from DE-AS 10 76 475 has electromagnetic actuated shortening elements. There is a separate circuit for each chord, which is closed when the corresponding key is pressed, which activates the corresponding shortening elements and sets the desired chord. Chords in different positions can be selected via relays. The shortening elements are attached over the entire length of the neck.
  • chords The choice of chords is determined when the devices are manufactured; the user cannot enable the setting of other chords without considerable technical effort.
  • Electronic devices are known for the automatic operation of a keyboard instrument, in particular a chime or a chime (DE-OS 29 02 606), which store whole pieces of music when playing, which can be called up again from the memories. These electronic devices control the playing of the instrument.
  • the stored pieces of music will easily do human work, like the mechanical-automatic instruments, to an external impulse, e.g. played from the activated clock.
  • the object of the invention is to create a stringed instrument with devices for setting chords or tone sequences, in which all chords or notes that are possible in the area of shortening elements are quickly inserted into the instrument.
  • the instrument After attaching the shortening and control elements, the instrument should remain handy and be conventionally playable.
  • the controls should be simple and easy to use.
  • the solution to this problem generally consists in the fact that an electronic device with one or more memories is available, from which the chords or tones can be called up by operating elements, whereby the corresponding shortening elements are actuated with the generated signals.
  • the memories are interchangeable and can be programmed from the outside or from the instrument.
  • the controls can either be firmly connected to the instrument at a point that does not interfere with normal playing or it is an attachable accessory that is easily connectable to the other devices installed in the instrument, so that by removing the control panel - Conventional gaming is now possible.
  • the beginner can thus be given an instrument with which he can also accompany difficult songs and play difficult chord sequences after a few hours of teaching and practice.
  • the advanced player is given the opportunity to effortlessly string together chord sequences as a soloist or in a group and with hand- to combine tones or chords in the conventional playing range.
  • the player has the option of setting previously set chords on the instrument by pressing a button, an electronic display showing which program, which chord number and which chord he has set.
  • the new style of play possibly combined with conventional style of play, can lead to compositions in all areas of music, e.g. modern, pop, classical, etc., since new ways of playing are opened.
  • the invention can be used for all stringed instruments in which the pitch is formed by shortening the strings and on which chords are played.
  • FIG. 1 is a perspective schematic view of a string instrument in the form of a guitar
  • FIG. 2a shows a section along the section line Ila-IIa in Fig. 2,
  • FIG. 3 shows a schematic perspective illustration of a modified embodiment which can be attached to the neck of a guitar
  • 4 shows a schematic longitudinal section through a neck part
  • FIG. 5 shows a cross section along the section line V-V in FIG. 4,
  • FIG. 6 shows a cross section of a modified embodiment according to the section line VI-VI in FIG. 1,
  • Fig. 7 shows a cross section through the neck along the section line VII-VII in Fig. 1 and

  • FIG. 1 shows a schematic perspective view of a guitar 10.
  • this guitar 10 consists of a resonance body 12 and a fretboard 24.
  • the fretboard 24 is located on a neck 14 which merges into a head 16 on which a known mechanism 34 for tuning the instrument is located.
  • the guitar 10 has shortening elements 70 for simple. Setting chords to. These are located on and in a ceiling
  • FIG. 1 In the embodiment of FIG. 1 is also one
  • the mechanism 34 is designed beyond a saddle 32 in a manner known per se in such a way that the pegs 36 customary for tuning the strings 30 are located only on one side of the head 16.

  • the strings 30 can be guided next to or below the cover plate 50 to the mechanism 34.
  • chords stored in electronic memories 90 are called up.
  • pulses are emitted from the electronic memory 90 (FIG. 4) to the corresponding shortening elements 70 to 78, which change the length of the respective string 30 so that the desired chord can be made to sound by the player of the guitar 10.
  • pickups for amplifiers can additionally be installed.
  • the guitar 10 can also be played in a conventional manner in all of the exemplary embodiments. In the example of FIGS. 1, 2 and 2a, this is possible without further changes to the guitar 10.

While the shortening elements 70 only indicated in FIG. 1 are described in more detail in their effect as an embodiment below with reference to FIG. 6, the game automatism will first be described in more detail with reference to the exemplary embodiment according to FIGS. 2 and 2a.

It is essential that the string 30 can be gripped by a gripping plate 72 instead of the human finger. The string 30 can be pressed from below by the gripping plate 72, which shortens the string 30 and therefore sounds in the desired pitch. For each string 30 and fret 26, a gripping plate 72 can be moved upward, as a result of which the corresponding chords are formed in accordance with the presetting. 2, the hatched gripping plates 72 are activated, as a result of which the chord F 7 sounds.
  • the cover plate 50 additionally attached according to the invention can be explained in more detail with reference to FIG. 3. This carries the controls for automatic gaming. The description of the operating elements also applies to the arrangement of the cover plate 50 according to FIG. 1.

  • the drawing shows how the string 30 is pressed up by actuating one of the devices, namely the fourth device, the gripping plate 73, as a result of which the string 30 rests on the fourth fret 28 of the cover plate 50 and therefore by four semitones sounds higher. If this happens, for example, with the A string, the tone is set to C sharp. If, exceptionally, a string 30 should not sound because there is no suitable tone within the range of the shortening element, the corresponding one will be used

Abstract

L'instrument à cordes présente des éléments (70, 100) pour raccourcir les cordes qui remplacent la main pour la production d'accords ou de notes. Les différents accords sont commandés au moyen de touches (52-58) reliées à des mémoires programmables et interchangeables. Les éléments (70, 100) commandés par impulsions modifient la longueur des cordes et permettent de jouer les accords désirés pendant le temps voulu. Les touches (52-58) permettent le choix des accords et leurs variations, un bouton (58) permet de jouer une suite donnée d'accords. Un affichage (110) facilite le choix et indique quel accord est commandé. Un dispositif d'amortissement des cordes permet de produire des variations rythmiques.
