It is assumed that the right little finger "5" touches the black key 12 of the mid-tone shifted up and down, the original ""," key, that is, the middle key "5" 6, because it is close to the g1 key and the original ":;" key. The right index finger "2", the right middle finger "3" and the right ring finger "4" respectively touch the black key 9 of the middle key shifted up and down, the original M key; the black key 10 of the middle key shifted up and down, the original "<" key; the black key 11 of the middle key shifted up and down. , the original “>” key. Because the a1 key, the original Q key, that is, the middle “6” key 7, is close to the top of the base key “4”, it is struck by the right ring finger “4”; the b1 key, the original L key, that is, the middle “7” key 8, is close to the base key “3”, and is struck by the left middle finger “3”. The black key 13 of the middle note, which is raised and lowered by a semitone, is next to the a1 key, the original 0 key, that is, the middle “6” key 7, and is touched by the left little finger “5”.

The frequency modulation signals triggered by these corresponding audio notes are quickly responded to by the internal CPU of IC1 for calculation and processing, and then amplified by the audio circuit of IC2, and finally pushed to the speaker B to emit sound. Different key switches are positioned at specific frequencies, emitting notes of different scales. Under continuous and rhythmic operation, melodic music is emitted.
