I do it in a way that is upwards compatible, specifically, if one puts all note 
names into the table, as is the case now, and no separate accidentals, the 
result is exactly the same as currently.

Also, rather than writing pitch and accidental names separately with a 
separator like a space, I split the note name that is parsed, so that is also 
upward compatible, and avoids having to tweak the lexer and parser.

So "f es” is two notes as before, whereas “fes” a single note. 

In German, one could this keep it as it is, or define the note names c d e f g 
a b h, plus the accidentals is es, and the microtonal accidentals ih eh. Doing 
the latter, “feses” is split up as “f es es”, and their pitch and alterations 
values added. But one gets more combinations, for example “fisih” and “fihis” 
will be the same, as they are split up as “f is ih” and “f ih is”. Also, any 
number of accidental names can follow the note name.
