J.S. Bach
Early Digital
Artist
Organization of musical tones
into notes ordered by frequency and separated by semi-tones
Consonance was the basis of composition
Most significant was the octave
(C to C' to C'') defined by a doubling (x2) of frequency
Next most significant was the fifth
(C to G to D to A...) defined by x1.5 frequency

Problem: Where do you put the notes?
