Provided herein is a method, computer program product and electronic device for assigning a set of pitches to a plurality of physical keys of an electronic device. The method may include the steps of obtaining an input chord, disassembling the chord into at least one base note and a plurality of individual voices, arranging a predetermined number of voices of the chord according to at least one predefined rule, and assigning at least one set of pitches to a plurality of physical keys of an electronic device, said set of pitches corresponding to the base note and arranged predetermined number of voices of the chord.
