otonality

plural otonalities

1. entertainmentA family of pitches that can all be expressed as ratios with a specified fixed tone, such that all ratios have the same denominator.

   Multiples up from otonalities, whereas divisors change the harmonic center and introduce new tonal sense (utonality).

   A similar correlation is evident in the physical layout of the Kithara II, which consists of twelve banks of six strings, each bank tuned to a specific, although incomplete, otonality or utonality.

   So an otonality based on the 1-limit would have a 1-Identity (its first pitch), a 3-Identity (its second pitch), a 5-Identity (its third pitch), and so on.
