Bang.Music.Class

Description

Implements the core data structures for use in the Bang library.

Synopsis

Documentation

Primitive objects in music are simply notes with duration and type, or rests with only duration.

Constructors

Note	A `Note` with duration `dur` and type `ntype`
Fields dur :: d ntype :: a
Rest	A `Rest` with duration `dur`
Fields dur :: d

Instances

Functor (Primitive dur)
(Eq d, Eq a) => Eq (Primitive d a)
(Show d, Show a) => Show (Primitive d a)

data Music dur a Source

A musical composition with duration type dur (typically Dur) and instrument type a (typically a PercussionSound)

Constructors

Prim (Primitive dur a)	A Primitive musical object.
(Music dur a) :+: (Music dur a)	Sequential composition of music
(Music dur a) :=: (Music dur a)	Parallel composition of music
Modify Control (Music dur a)	Modifier (typically `BPM` or `Tempo` change)

Instances

Bifunctor Music
Bifoldable Music
Functor (Music dur)
Foldable (Music dur)
(Eq dur, Eq a) => Eq (Music dur a)
(Show dur, Show a) => Show (Music dur a)
Num dur => Monoid (Music dur a)

Simple data type representing different control structures for compositions.

Constructors

BPM Integer	Set the beats per minute (WARNING: Only set this once, or BPM will multiply!)
Tempo Rational	Set the speed for a section of music (default 1)
Instrument InstrumentName	Change the instrument (currently unused)
