Fields

clef_t :: Clef_T

clef_octave :: i

Instances

Integral i => Eq (Clef i)

Integral i => Ord (Clef i)

(Integral 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.
