Documentation

module Temporal.Music.Western

tone :: Step -> Score (Note a)

Constructs Score with one note. Scale is set to equal tempered scale (from c1).

Steps

Step defines a value of type score (hence Track), so we can transform them on the fly:

 qn $ line [forte c, d, e, low b, forte $ bn d]

c :: Score (Note a)

d :: Score (Note a)

e :: Score (Note a)

f :: Score (Note a)

g :: Score (Note a)

a :: Score (Note a)

b :: Score (Note a)

cs :: Score (Note a)

ds :: Score (Note a)

es :: Score (Note a)

fs :: Score (Note a)

gs :: Score (Note a)

as :: Score (Note a)

bs :: Score (Note a)

cf :: Score (Note a)

df :: Score (Note a)

ef :: Score (Note a)

ff :: Score (Note a)

gf :: Score (Note a)

af :: Score (Note a)

bf :: Score (Note a)

Scales

eqt :: Hz -> Scale

12 tone equal temperament scale

pyth :: Hz -> Scale

pythagorean scale

hind :: Hz -> Scale

hindemithean scale with mean of fs and gb for tritone

hindFs :: Hz -> Scale

hindemithean scale with fs for tritone

hindGb :: Hz -> Scale

Examples

Little example of usage:

 import Temporal.Music.Western.P12

 res :: Score ()
 res = str 0.2 $ har [
            qn $ mel [c, c, bn g, e, dbn f],
            low $ mel [c, c, d, low a]]
