tidal-chord's Introduction

tidal-chord

tidal-chord is an add-on to the amazing live coding project tidal

chord format

Chord format is inspired from the ableton live glasgow tool ( https://github.com/asb2m10/glasgow)

Note name: A B C D E F G with # and b.

Mode Name: M(Major) m(Minor) Ionian Dorian Phrygian Lydian Myxolidian Aeolian Locrian

Scale Degre(optional): ° [1-7] degre in scale where the chord is applied

Neighbour key tonality(optional) : +(one step in circle of fifth) or -(one step in circle of fourth)

Relative Mode(optional) : > [Mode Name] convert scale to the relative mode

Chord Definition: | [Chord Name or Chord degres sep by - ]

Chord Name can be one of the following : Maj | Min | Maj7 | Min7 | Dom7 | Maj6 | Min6 | Five | Sus4 | Sus2 | MajorAdd2 | MinorAdd2 | Dom9 | Dom13 | Min9 | Maj9 | Maj13 | Min11

Invertion : !

 chordToNotes "C3M|3-7" = [60,64,71]
 chordToNotes "C3M|Min9!!" = [63,70,72,74,79]
 chordToNotes "C3°4M>m|Min!!" = [77,86,93]

Usage

This examples use also the tidal-midi package

:load "TidalChord.hs"
import Sound.Tidal.MIDI.Context

devices <- midiDevices
m1 <- midiStream devices "VMidi 1" 1 synthController

m1 $ midiChord "~ C2M*3 ~ C2°5M*2 C3°7M/2" # velocity (Sound.Tidal.Context.scale 0.1 0.6 (slow 8 $ sine1))

m1 $ midiChord "C3M- C3°7M-*2 C2°5M-|3-5-9/2 "
