<p>A musical notation for diatonic and chromatic accordions according to the invention is determining, in addition to the clear determination of a single tone, also visually without ambiguity the relation between a particular tone and the position of the key activating this tone within the accordion when the bellows are extended or compressed. The musical notation consists of parallel lines (1) and musical notes (7) where the lines (1) with interspaces (2) among the lines (1) and two fields (3) above and under the lines (1) match the 12 rows of buttons on the accordion keyboard. A colour or another optional graphical designation (9) of the musical notes (7) is determining the position of the respective button in a given column of the accordion keyboard. The direction of the movement of the bellows at a given tone is represented by the graphical designation of the line (1) background (9) where the musical note (7) representing the tone produced by the extension or compression of the bellows is to be found.</p> |
