Just intonation point

JIP (just intonation point), or commonly denoted "J", is a point in p-limit tuning space ⟨log₂2 log₂3 log₂5 … log₂p]. If M is a monzo, then <J|M> is M evaluated in terms of octaves. If we shift to weighted coordinates, so that M = [m₂ m₃ m₅ … m_p⟩ is represented by the ket vector [e₂log₂2 e₃log₂3 e₅log₂5 … e_plog₂p⟩, then J becomes correspondingly the bra vector ⟨1 1 1 … 1].
