Instances

Eq i => Eq (Clef i)

Ord i => Ord (Clef i)

Show i => Show (Clef i)

clef_range :: Clef_T -> Maybe (Pitch, Pitch)

Give clef range as a Pitch pair indicating the notes below and above the staff.

map clef_range [Treble,Bass] == [Just (d4,g5),Just (f2,b3)]
clef_range Percussion == Nothing

clef_suggest :: Integral i => Pitch -> Clef i

Suggest a Clef given a Pitch.

map clef_suggest [c2,c4] == [Clef Bass (-1),Clef Treble 0]

clef_zero :: Integral i => Clef i -> Clef i

Set clef_octave to 0.

clef_restrict :: Integral i => i -> Clef i -> Clef i

Set clef_octave to be no further than r from 0.
