data ScaleMap Source #

Constructors

ScaleMap
Fields layout :: Layout laras_map :: Map Text BaliScales.Laras default_laras :: BaliScales.Laras format :: Format

data Instrument Source #

Constructors

Instrument
Fields center :: Pitch.Octave bottom :: Absolute top :: Absolute Unlike most ranges, this is inclusive, so top is a valid pitch. This seems more intuitive for instruments, and besides there's no need for an empty range.

data Absolute Source #

An absolute pitch as parsed from Pitch.Note, so e.g. 1-7 (for 1-7). This is the "chromatic" representation, while Pitch is the diatonic one, taking pathet into account.

TheoryFormat has a similar notion of relative to absolute, but it's the other way around, in that Pitch.Pitch is the absolute one, while Pitch.Note is relative.

Constructors

Absolute !Pitch.Octave !Pitch.PitchClass

Layout

Fields

start :: Pitch.PitchClass
Absolute (chromatic) step on which intervals starts, to map from Absolute to Pitch and back.
intervals :: Intervals
theory :: Theory.Layout
d_to_c :: Vector.Vector Chromatic
Cache diatonic to chromatic mappings.
c_to_d :: Vector.Vector (Diatonic, ChromaticSteps)
degree_to_pc :: Map Pitch.Degree Pitch.PitchClass
This is like d_to_c, except it includes chromatic steps as accidentals, so it can map from the ascii kbd. TODO merge with d_to_c.

Tuning

data Laras Source #

Describe the frequencies in a saih. This doesn't say what the range is, since that's in the ScaleMap, and all saihs in one scale should have the same range.

Constructors

Laras
Fields name :: Text doc :: Doc.Doc base :: Pitch.Pitch The pitch where `umbang` and `isep` start. It should be such that octave 4 is close to middle C. umbang :: Vector.Vector Pitch.NoteNumber isep :: Vector.Vector Pitch.NoteNumber
