The technique is a means of

ensuring that all 12 notes of the chromatic scale are sounded

as often as one another in a piece of music while preventing

the emphasis of any one note[3] through the use of tone rows ,

an ordering of the 12 pitches.

 

 

The 12 pitches are:

C   C#   D   D#   E   F   F#   G   G#   A   A#  B
