I came across the fact that Klingon music uses a nonatonic music scale. I then found that they have a nonave as opposed to an octave. I found this curious because it did not make sense to me. The Western music scale is traditionally heptatonic (seven notes) and thus has an octave. I would think that instead the nonatonic scale would imply a decave. On another note, has it ever been decided what the human equivalent of the nine notes in the scale are?
