Note that the mid-5th is spelled as a double-up dim 5th from the chord root (^^Gb) if the 3rd is upped, but as a double-down 5th (vvG) if the 3rd is downed. This avoids the interval from the 3rd to the 5th being spelled with a triple up or down. | Note that the mid-5th is spelled as a double-up dim 5th from the chord root (^^Gb) if the 3rd is upped, but as a double-down 5th (vvG) if the 3rd is downed.

In addition, there are unconventional scales like the whole tone, diminished and Tcherepnin scales. But these are much less common, because they don't map to a compact shape in the JI lattice. (See "Convexity and the well-formedness of musical objects", Aline Honingh and Rens Bod, Journal of New Music Research, 2005.) | In addition, there are unconventional scales like the whole tone, diminished and Tcherepnin scales.

41-edo has an enormous variety of scales. There are many thousands of unconventional scales, but here I will focus on the ones that map compactly to the JI lattice. These are scales that contain numerous perfect 5ths. | 41-edo has an enormous variety of scales.

In Western music, harmonies often require notes that the melody doesn't. For example, "Auld Lang Syne" has a pentatonic melody but diatonic harmonies. Often the melody is diatonic but the harmonies are at least somewhat chromatic. The score will have accidentals in the piano part but not the vocal part. | In Western music, harmonies often require notes that the melody doesn't.
