  • This invention relates to a device for the assembly and identification of chords in fretted stringed instruments such as 0 guitars, electric guitars and the like, through the visualization of the relative and absolute location of musical intervals on the instrument's finger board and its respective methods of utilization.
  • chords are made up of two or more musical notes taken from the chromatic scale.
  • Each note of the chord may be character zed by step and half step interval or intervals h i exist between the given note and the tonic note or degree "l" of the chord.
  • each note of a chord receives a notation referring to the interval where it is located in relation to degree "1" of the chord.
  • a chord in "G” Major is made up by the note “Sol” or “G”, corresponding to the degree "1", by the note “Si” or “B”, corresponding to the major third interval, "3M”, and the note “Re” or “D” , corresponding to the perfect fifth interval, "5J".
  • chord relative to a tonic note other than “G” will also be made up by the degree “1” and the intervals, " 5 " and “5J", being however, such intervals relative to musical notes different from the pi vioui' case.
  • the intervals define the relative locations between the notes that make up the chords.
  • To the set of intervals that make up a given chord it is given the name of chord formula.
  • « chor ⁇ is therefore defined by its chord formula, that is specific for the definition of the relative location between the notes, and by the tonic note, specific for defining the absolute location of the notes in the chromatic scale.
  • a same note can correspond to any interval, depending on the tonic note of the chord.
  • each string fret on the instrument's finger board corresponds to a musical note and, at the same time, may correspond to any interval, depending on the tonic note of the chord under study.
  • chords in the instrument demand the previous knowledge of a large amount of information relative to the various musical scales with their respective intervals, as well as the musical notes corresponding to each fret and string on the instrument's finger board.
  • chords due to the enourmous nurnbe i ol lin ⁇ oi i ⁇ g c m i e- tions, the dictionaries of chords require a considerable effort, of counsulting to choose the more appropriate chord position to the desired musical context. More over, as they do not identify the musical intervals correspondent to each fingered fret string, 5 such dictionaries do not favor the visualization of the interval location on the instrument's finger board and, as a consequence, they do not favor the knowledge for the assembly of chord or for the identification of played chords.

Abstract

Dispositif permettant de composer et d'identifier des accords sur les instruments à cordes pincées tels que les guitares, les guitares électriques ou analogue, et procédés correspondants. Ce dispositif est essentiellement constitué d'un curseur (1) présentant les intervalles musicaux constituant les accords, disposés dans des positions relatives qui correspondent à leurs positions sur la touche de l'instrument. Ledit curseur glisse sur un support fixe (2) muni de fenêtres (21) par lesquelles on peut voir les intervalles. Pour chaque tonique, on règle le curseur sur le support fixe de telle manière que l'on puisse voir, par les fenêtres du support, tous les intervalles qui constituent un ou plusieurs types d'accords, situés dans des positions identiques à celles qu'ils ont sur la touche de l'instrument. Par conséquent, on peut voir directement sur le dispositif l'ensemble des doigtés d'accord possibles, et les transposer sur l'instrument, et inversement.
