foldr1 :: forall a. (a -> a -> a) -> NonEmptyList a -> a

utility functions that should probably belong in various Purescript libraries

rMax :: Rational -> Rational -> Rational

rMin :: Rational -> Rational -> Rational

Operator alias for Data.Euterpea.Transform.cutm (left-associative / precedence 5)

MoreMusic proper

line :: forall a. List (Music a) -> Music a

chord :: forall a. List (Music a) -> Music a

line1 :: forall a. NonEmptyList (Music a) -> Music a

chord1 :: forall a. NonEmptyList (Music a) -> Music a

offset :: forall a. Dur -> Music a -> Music a

times :: forall a. Int -> Music a -> Music a

lineToList :: forall a. Music a -> List (Music a)

how do I pattern match on Rationals? how do I return an error?

invertAt :: Pitch -> Music Pitch -> Music Pitch

invertAt1 :: forall a. Pitch -> Music (Tuple Pitch a) -> Music (Tuple Pitch a)

invert :: Music Pitch -> Music Pitch

invert1 :: forall a. Music (Tuple Pitch a) -> Music (Tuple Pitch a)

dur :: forall a. Music a -> Dur

cut :: forall a. Dur -> Music a -> Music a

remove :: forall a. Dur -> Music a -> Music a

type LazyDur = List Dur

durL :: forall a. Music a -> LazyDur

mergeLD :: LazyDur -> LazyDur -> LazyDur

minL :: LazyDur -> Dur -> Dur

cutL :: forall a. LazyDur -> Music a -> Music a

cutm :: forall a. Music a -> Music a -> Music a

mFold :: forall a b. (Primitive a -> b) -> (b -> b -> b) -> (b -> b -> b) -> (Control -> b -> b) -> Music a -> b

shiftPitches :: AbsPitch -> Music Pitch -> Music Pitch

Sometimes we may wish to alter the internal structure of a Music value rather than wrapping it with Modify. The following functions allow this.

shiftPitches2 :: AbsPitch -> Music Note1 -> Music Note1

shiftPitches1 :: forall a. AbsPitch -> Music (Tuple Pitch a) -> Music (Tuple Pitch a)

shiftPitches2 is useless unless we model Note1 as a Tuple

scaleDurations :: forall a. Rational -> Music a -> Music a

changeInstrument :: forall a. InstrumentName -> Music a -> Music a

removeInstruments :: forall a. Music a -> Music a
