Synopsis

Accidentals

data Accidental Source

Accidental, represented as number of alterations. Generalized from natural and single/double sharp/flat to any number of steps.

Instances

Enum Accidental
Eq Accidental
Integral Accidental
Num Accidental
Ord Accidental
Real Accidental
Show Accidental
Alterable Accidental
(IsPitch a, Alterable a) => IsPitch (Accidental -> a)	Magic instance that allow us to write `c sharp` instead of `sharpen c`.

natural :: Accidental Source

The natural accidental.

flat :: Accidental Source

The flat accidental.

sharp :: Accidental Source

The sharp accidental.

doubleFlat :: Accidental Source

The double flat accidental.

doubleSharp :: Accidental Source

The double sharp accidental.

Inspecting accidentals

isNatural :: Accidental -> Bool Source

Returns whether this is a natural accidental.

isFlattened :: Accidental -> Bool Source

Returns whether this is a flat, double flat etc.

isSharpened :: Accidental -> Bool Source

Returns whether this is a sharp, double sharp etc.

isStandardAccidental :: Accidental -> Bool Source

Returns whether this is a standard accidental, i.e. either a double flat, flat, natural, sharp or double sharp.

mkPitch :: Name -> Accidental -> Pitch Source

Creates a pitch from name accidental.

name :: Pitch -> Name Source

Returns the name of a pitch.

To convert a pitch to a numeric type, use octaves, steps or semitones on the relevant interval type, for example:

semitones ('a\'' .-. c)

accidental :: Pitch -> Accidental Source

Returns the accidental of a pitch.

See also octaves, and steps and semitones.

Diatonic and chromatic pitch

upDiatonicP :: Pitch -> DiatonicSteps -> Pitch -> Pitch Source

downDiatonicP :: Pitch -> DiatonicSteps -> Pitch -> Pitch Source

upChromaticP :: Pitch -> ChromaticSteps -> Pitch -> Pitch Source

downChromaticP :: Pitch -> ChromaticSteps -> Pitch -> Pitch Source
