Its full specification is (n-)AFSp: (n pitches of an) arithmetic frequency sequence adding by (irrtional) interval p. The only difference between an [[OS|OS (overtone sequence)]] and AFS is that for OS the p is rational. | Its full specification is (n-)AFSp: (n pitches of an) arithmetic frequency sequence adding by (irrtional) interval p.
