43edo: Difference between revisions

Line 457:

For people who aren't colorblind, a red-note/blue-note system (similar to that proposed for [[36edo]]) can be used. (Note that this is different than Kite's [[color notation]].) Now we have the following sequence of notes, each separated by one meride: '''A''', '''A''', '''A♯''', '''A♯''', '''B♭''', '''B♭''', '''B''', '''B'''. (Note that red sharps or blue flats are enharmonically equivalent to simpler notes: '''A♯''' is enharmonic to B♭, and '''B♭''' is actually just A♯).

The diatonic semitone is four steps, so for the region between B and C, we can use: B, C♭, '''B♯''' / '''C♭''' (they are enharmonic equivalents), B♯, and C. All of the notes in 43edo therefore have unambiguous names except for '''B♯''' / '''C♭''', and '''E♯''' / '''F♭'''. It might also be possible to design special symbols for those two notes (resembling a cross between the letters B and C in the former case, and E and F in the latter).

If '''C♭''' and '''B♯''' (and '''F♭''' / '''E♯''') are instead forced to be distinct, but the requirement that all notes be equally spaced is maintained, then we end up with a ''completely'' unambiguous red-note/blue-note notation for [[45edo]], which is another meantone (actually, a [[flattone]]) system.
