Module Music.Prim

Music primitives.

Primitives

type 'a t = [
| `Note of dur * 'a(*

Interpret note for given duration.

*)
| `Rest of dur(*

Rest for given duration.

*)
]

The type for music primitives. Either a note of type 'a or a rest (silence).

val note : dur -> 'a -> 'a t

note d n is `Note (d, n), interprets note n for duration d.

val rest : dur -> 'a t

rest d is `Rest d, rests for duration d.

Properties

val dur : 'a t -> dur

dur p is p's duration in whole notes units.

Traversals

val map : ( 'a -> 'b ) -> 'a t -> 'b t

map f p maps the note of p with f.

val map_dur : ( dur -> dur ) -> 'a t -> 'a t

map_dur f p maps duration of p with f.

val fold : note:( dur -> 'a -> 'b ) -> rest:( dur -> 'b ) -> 'a t -> 'b

fold ~note ~rest p folds over p with note and rest.
