Legend for the notes
--------------------

mapping of srgmpdns notation and western notation (assuming scale "C"):
s  = sa    = C
r1 = ri 1  = C#
r2 = ri 2  = D       (= g1 = ga 1)
g2 = ga 2  = D#      (= r3 = ri 3)
g3 = ga 3  = E
m1 = ma 1  = F
m2 = ma 2  = F#
p  = pa    = G
d1 = da 1  = G#
d2 = da 2  = A       (= n1 = ni 1)
n2 = ni 2  = A#      (= d3 = da 3)
n3 = ni 3  = B
S  = sa    = C [next octave; higher "sa"]
and so on


Notes with suffix "."  are of lower octave
Notes written in Caps in "srgm" notation (or with suffix "+" in western) are of higher octave
