type ScaleDegree = Int Source #
data PatternGroup Source #
A pattern group is one of the patterns of a piece of music, identified by an expert or algorithm, and defined by a pattern prototype and other pattern occurences.

A simplistic music note (only time and pitch).
type MusicPiece = Pattern Source #
A piece of music is a huge pattern.
basePitch :: Pattern -> Maybe MIDI Source #
The base pitch of a pattern (the pitch of its first note). e.g. basePitch [(25,1), (27,2), (25,2.5)] = Just 25
pitch :: Pattern -> [MIDI] Source #
The (real) pitch structure of a pattern. e.g. pitch [(25,1), (27,2), (25,2.5)] = [25, 27, 25]
intervals :: Pattern -> [Interval] Source #
The (relative) pitch structure of a pattern. e.g. intervals [(25,1), (27,2), (25,2.5)] = [2, -2]
onsets :: Pattern -> [Time] Source #
The (real) rhythmic structure of a pattern. e.g. onset [(25,1), (27,2), (25,2.5)] = [1, 2, 2.5]
durations :: Pattern -> [Time] Source #
The (relative) rhythmic structure of a pattern. e.g. rhythm [(25,1), (27,2), (25,2.5)] = [1, 0.5]
normalRhythm :: Pattern -> [Time] Source #
Normalized (relative) rhythmic structure of a pattern. e.g. normalRhythm [(A,2), (C#,6), (Eb,8), (B,1), (A,2)] = [1, 3, 4, 1/2, 1]
translateH :: Time -> Note -> Note Source #
Translate a note horizontally (in time). e.g. translateH (-0.5) [(25,1), (27,2), (25,2.5)] = [(25,0.5), (27,1.5), (25,2)]
translateV :: Interval -> Note -> Note Source #
Translate a note vertically (in pitch). e.g. translateV (-20) [(25,1), (27,2), (25,2.5)] = [(5,1), (7,2), (5,2.5)]
pairs :: [a] -> [(a, a)] Source #
Get list as pairs of consecutive elements. e.g. pairs [a, b, c, d] = [(a, b), (b, c), (c, d)]
createScaleInC :: ScaleType -> Scale Source #
createScaleInD :: ScaleType -> Scale Source #
guessScale :: Pattern -> Scale Source #
