This uniform structure of the Helmholtz-Ellis and Sagittal notation  
makes it possible to not only notate just intonation but also  
arbitrary equal temperaments (equal divisions of the octave) with  
them. The example below shows the pitches of 41-tone equal temperament  
with Helmholtz-Ellis notation. Note that other enharmonic pitches are  
possible, for example, Db and C#L (C# transposed down by a septimal  
comma) share the same 41-tone equal temperament pitch class (namely  
pitch class 3, the fourth note below).

BTW: this example also shows again the problem that the space between  
an accidental and its related note is larger than the space between  
the accidental and the previous note. Any idea how to fix that?

Thank you!
