Abstract
An electronic musical instrument comprises a note code producer for producing note codes respectively having n bits representing juxtaposed notes aligned by a semitone interval step. The note codes to be generated are selected from a binary code table consisting of successively aligned binary values corresponding to an order of alignment of the notes in a musical scale and the table omits either one of the largest and smallest values to be represented by the lowest m bits (n>m). A modified note code generator produces modified note codes by repetitively adding the lowest m bits of each note code to further lower order digits below the least significant bit of each note code, and a sound system generates musical tones having frequencies corresponding to the modified note codes.
