pitch classes

cdefgabrR

pitches are always relative to key signature

e.g. key:g => f sharp, key:gm => b flat, e flat

accidentals

b+b@b # accidentals are valid until next accidental or end of line

• => sharpen relative to key signature

• => flatten relative to key signature @ => back to default (from key signature) ++ => double sharpen -- => fouble flatten ? => cautionary accidental (with parens) ! => force show accidental

b+bb@bb!
