User:MisterShafXen/26edo notation

26edo can be notated as a superset of 13edo as follows: A At A#/Bb Bd B Bt B#/Cb Cd C Ct C#/Db Dd D Dt D#/Eb Ed E Et E#/Fb Fd F Ft F#/Gb Gd G Gt/Ad (A) An A major chord would be spelled A C Ed and would be called A perfect (m5). This is because Cd is the m3 and Ct is the M3, E natural is P5 from A natural. A B major chord would be spelled B D Fd. A C major chord would be spelled C E Gd. A D major chord would be spelled D F At, which would look like a D perfect (M5). The reason for this quirk is that G-A is 1\13 and not 2\13.

An A major scale would be spelled A B C Dd Ed Fd Gd, with the following key signature: Dd Fd Ed Gd.
