===Notes ===
The octave is divided into 41 equal steps, a tuning called 41-ET or 41edo or 41-equal. Whereas 12-equal has 100¢ steps, 41-equal has steps of 29.27¢. We can round this off to 30¢ for convenience, since a cent or two doesn't matter much in practice. This 30¢ interval is called an arrow, because the little arrows by the noteheads raise or lower the pitch by 30¢. Notes are called up-E, down-F-sharp, etc., written ^E and vF#. A note that has no ups or downs is called plain. The 7 plain natural notes are close to 12-equal, but they do deviate slightly. The pattern is easy to see when the notes are arranged in chain-of-5ths order:

===Key signatures===
The key signature is divided into two regions. The #/b region is as usual, except it can also have ## and bb. The arrow region consists of up to two arrow stacks, a quadruple one for the tonic, 2nd 4th and 5th, and a triple one for the 3rd, 6th and 7th. Both stacks always have the same shape. The quadruple stack has 2 columns of arrows with the lowest arrow indicating the tonic. The triple stack has the lowest arrow on the 3rd. Down-A downmajor looks like this:
 
[[File:VA vMajor keysig.png]]
 
The scale is vA vB vvC# vD vE vvF# vvG# vA. Down-A upmajor would omit the triple stack. Down-A plain major would have a triple stack with downs instead of duds.

=== How to read the chord names ===
=== Chord names===
Any chord name without ups or downs is exactly what one would expect it to be. Cm7 is still C Eb G Bb. But in practice most chords have ups and downs in them. An up or down between the chord root and the chord type (e.g. C^m7) raises or lowers the 3rd, and also the 6th, 7th or 11th, if present. Thus C down-seven is the usual C7 chord with the 3rd and 7th downed: Cv7 = C vE G vBb. Mnemonic: every other note of a stacked-3rds chord with a 6th below the root is affected: '''6th''' - root - '''3rd''' - 5th - '''7th''' - 9th - '''11th''' - 13th. Note that the 6th is affected, but the 13th is not.
