Fughetta

A JFugue wrapper for Clojure with some ideas from [Haskore] (http://www.haskell.org/haskellwiki/Haskore)

Installation

Add depencency to lein/cake project:

[fughetta "0.0.1-SNAPSHOT"]

Usage

Import into your namespace:

(:use fughetta.core)

Notes, durations and chords as functions

  • Defaults
  (cs) => "[61]" = "C#"   
  (q-) => "Rq."
  • Octave
  (c 6) => "[72]" = "C6"
  • Durations
  (c 6 q i) = (i (q (c 6))) => "[72]qi"
  • Chords
  (maj (q (c)))   => "[60]majq"
  (minor (d 6 w)) => "[74]minw"

Patterns

Use the pattern function to join notes (collections will be flattened!)

  (pattern 
    (c) (d) (e)
    [(f) (g)]
    (repeat 2 [(c) (d) (e)]))
  => " [60] [62] [64] [65] [67] [60] [62] [64] [60] [62] [64] "

Instruments and rhythms

  • Instruments
  (inst :distortion-guitar (c) (d) (e)) => "I[DISTORTION_GUITAR] [60] [62] [64]"
  • Rhythms (subject to change)
  (let [x "q"
        - (q)]
    (rhythm
      :bass-drum      [x - - - x - - - x - - - x - - -]
      :electric-snare [- - x - - - x - - - x - - - x -]
      :closed-hi-hat  [x x x x x x x x x x x x x x x x]))

Combining Notes

  (++ (c) (d) (e))      => "[60]+[62]+[64]"
  (++ (c) (-- (d) (e))) => "[60]+[62]_[64]"

Tuplets

  • Triplets
  (*** (c 5 q) (d 5 q) (e 5 q)) => " [60]q* [62]q* [64]q* "
  • Other tuplets
  (** 2 (c 5 q) (d 5 q) (e 5 q)) => " [60]q*3:2 [62]q*3:2 [64]q*3:2 "
  (** 4 (map q (c) (d) (e) (f) (g))) => " [60]q*5:4 [62]q*5:4 [64]q*5:4 [65]q*5:4 [67]q*5:4 "

Moving through semi-tones

  (>> (c))   => "[61]"
  (>> (c) 4) => "[65]"
  (<< (c))   => "[59]"
  (<< (c) 4) => "[56]"

Voices and controllers

  • Voices
  (voice 1 (c) (d) (e))
  • Tempo
  (tempo 150 (c) (d) (e))
  • Volume
  (vol 1500 (c) (d) (e))

Player

  • Play
  (play! (c) (d 5) (e 5 q))
  • Stop
  (stop!)
  • Save to file
  (save! "filename" (c) (d 5) (e 5 q))
