I do!  Then there are the known cases of flute players rolling the
mouthpiece to change pitch, trumpet players bending, violin.  The 3rd
of a scale is slightly sharp in Bach's temper.  Semi-tones come up in
Theory class too.

note= Note( "C" )
third= MajorInterval( 3 )
print note+ third
: <NaturalNote("E"), slightly flat>
