Hans, I am late, but can I persuade you to try this with sharp and flat
representing 4 tone-steps rather than 5 ?
No, since in regular E53, the minor second m = 4, and the major second M = 9,
so sharps and flats alter with M - m = 5 E53 tonesteps.
But you also have arrow alterations, so you can distinguish more than two types
of second.
You have the diatonic scale of the bare note-names
C -9- D -9- E -4- F -9- G -9- A -9- B -4- C
but the major scale build on the major triads is closer to
C -9- D -8- E, -5- F -9- G -8- A, -9- B, -5- C
(with , lowering one step)
You might choose seconds from the set m=4 n=5 N=8 M=9 and have alterations
M - n = N - m = 4 close to a traditional sharp
M - N = n - m = 1 close to an 81/80 comma
then the D major scale, for example, looks more simple
D -9- E -8- F# -5- G -9- A -8- B, -9- C# -5- D
M-m = 5 steps is another choice for an alteration, but if I write that with a
sharp I find it harder to understand because I have learned that a sharp is a
tiny bit less than half a whole tone.
