These pitches form a chain, with each one separated from the next by a specific interval. This interval can be said to generate the notation, or the notation can be said to be based on this interval. In diatonic circle-of-fifths notation, this interval has been a just or near-just 3/2. Other intervals are possible, and even desirable for certain edos like 13, 18, and 23. | These pitches form a chain, with each one separated from the next by a specific interval.

[[Enharmonic equivalence]] may arise from this approach, which is when the same pitch can have multiple names. People are often taught that C♯ is enharmonically equivalent to D♭ but this is only true in [[12edo]] and its multiples (24edo, 36edo, etc.). The same term is sometimes used to refer to equivalence in general, but each edo technically has its own equivalence. [[7edo]] has the type of equivalence that could be called ''chromatic equivalence'', for example. | |||
