Create chord

chord  tonic (symbol), name (symbol)

Creates an immutable ring of Midi note numbers when given a tonic note and a chord type. If only passed a chord type, will default the tonic to 0. See examples.

Introduced in v2.0

Examples

# Example 1

puts (chord :e, :minor)

# returns a ring of midi notes - (ring 64, 67, 71)

# Example 2


play (chord :e, :minor)

# Play all the notes together

# Example 3


play (chord :e3, :minor, invert: 0)
play (chord :e3, :minor, invert: 1)
play (chord :e3, :minor, invert: 2)

# Chord inversions (see the fn chord_invert)
# Play the basic :e3, :minor chord - (ring 52, 55, 59)
# Play the first inversion of :e3, :minor - (ring 55, 59, 64)
# Play the first inversion of :e3, :minor - (ring 59, 64, 67)

# Example 4


puts (chord :minor)

# You can create a chord without a tonic:
#=> (ring 0, 3, 7)

# Example 5


live_loop :arp do
  play chord(:e, :minor, num_octaves: 2).tick, release: 0.1
  sleep 0.125
end

# chords are great for arpeggiators
