Basic functions

All basic functions (composition, time stretching, dynamic changing of volume and pitch etc, etc) live in this module.

module Temporal.Music

Volume

Dynamics values form 9-level equally spaced grid. They are from quietest to loudest: piano pianissimo (ppp), pianissimo (pp), piano (p), mezzo piano (mp), mezzo forte (mf), forte (f), fortissimo (ff), forte fortissimo (fff). These modifiers change level relative to the current level. It means that

 piano . forte = id

pppiano :: VolumeLike a => Score a -> Score a

ppiano :: VolumeLike a => Score a -> Score a

piano :: VolumeLike a => Score a -> Score a

mpiano :: VolumeLike a => Score a -> Score a

mforte :: VolumeLike a => Score a -> Score a

forte :: VolumeLike a => Score a -> Score a

fforte :: VolumeLike a => Score a -> Score a

ffforte :: VolumeLike a => Score a -> Score a

Shortcuts to set dynamics level.

ppp' :: VolumeLike a => Score a -> Score a

pp' :: VolumeLike a => Score a -> Score a

p' :: VolumeLike a => Score a -> Score a

mp' :: VolumeLike a => Score a -> Score a

mf' :: VolumeLike a => Score a -> Score a

f' :: VolumeLike a => Score a -> Score a

ff' :: VolumeLike a => Score a -> Score a

fff' :: VolumeLike a => Score a -> Score a

Envelops

dim :: VolumeLike a => Accent -> Score a -> Score a

diminuendo

cresc :: VolumeLike a => Accent -> Score a -> Score a

crescendo

Score

rondo :: Score a -> Score a -> Score a -> Score a

rondo form

rondo a b c = line [a, b, a, c, a]

reprise :: Score a -> Score a -> Score a -> Score a

reprise form

reprise a b1 b2 = line [a, b1, a, b2]

Tempo

Tempo terms specify not a rigid value but tempo range. So all terms are functions from relative power of term (it's value of type Double from 0 to 1) to some tempo value. Zero means the lowest value from tempo range and one means the highest value. To be used with bpm function.

type Tempo = Double

lento :: Double -> Tempo

very slow (40-60 bpm), like largo

largo :: Double -> Tempo

very slow (40-60 bpm)

larghetto :: Double -> Tempo

rather broadly (60-66 bpm)

grave :: Double -> Tempo

slow and sloemn (60 - 66 bpm)

adagio :: Double -> Tempo

slow and stately (literally at ease) (66-76 bpm)

adagietto :: Double -> Tempo

rather slow (70-80 bpm)

andante :: Double -> Tempo

at awalking pace (76-80 bpm)

andantino :: Double -> Tempo

slightly faster then andante (80-100 bpm)

moderato :: Double -> Tempo

moderately (101-110 bpm)

allegretto :: Double -> Tempo

moderately fast (115-125 bpm)

allegro :: Double -> Tempo

fast, at 'march tempo' (120-139 bpm)

vivace :: Double -> Tempo

lively and fast (135-160 bpm)

presto :: Double -> Tempo

very fast (168-200 bpm)

prestissimo :: Double -> Tempo

extremely fast (200 - 230 bpm)
