159edo/Notation
The 159edo-notation system proposed by Aura modifies the Helmholtz-Ellis notation in such a way that undecimal quartertones play a central role alongside the traditional accidentals.
The following table (under construction) shows the symbols and describes their function. The signs in the remarks section reflect absolute displacements, - means down, + means up.
