Device to facilitate musical instrument learning

A device (1) for a string musical instrument learning comprising a controller and a plurality of led lights configured to be able to change the color of their own light emission as a function of the instruction applied by said controller, said led lights being arranged in a plurality of columns (a, b, c) and a plurality of lines (r1, r2);

• said device (1) being configured so that each column corresponds to a key of a string instrument keyboard and each line corresponds to a string, so that each LED light is coupled univocally to a respective key of said string instrument keyboard;
• said controller (20) being configured to control the switching on, switching off and color of each one of said led lights, wherein each LED lights column is positioned on a respective adhesive support (10) configured to be glued to the handle of the string instrument, under the strings, in that it comprises further computing means on which computer programs are loaded, which are configured to carry out the method comprising the steps of:
• 100) subdividing said LED lights columns (a, b, c) in a first sub-assembly (10) of LED light columns relating to the keys of said string instrument keyboard, which can be pressed by the musician's hand, and in a second sub-assembly (11) of LED light columns relating to keys not used by the musician;
• 200) communicating to the musician the indication relating to the keys to be pressed by switching on the LED lights of said first sub-assembly (10), and at the same time, communicating to the musician the indication of the strings to be played and their rhythmical sequence by switching on the LED lights of said second sub-assembly (11) and in that said second sub-assembly (11) of columns of LED lights relating to keys not used by the musician comprises the closest columns to the hand executing the rhythmical part.
