When you run this code it will show output in the right hand pane pf the Sonic Pi application It lists: The scale names The chord names, and The note numbers for an Ae major chord It plays two scales major and minor and then the three inversions of a chord.

puts "An A3major chord is composed of "
puts chord :A3, "M"
play_pattern_timed scale(:d3, :major), 0.125, release: 0.1
play_pattern_timed scale(:d3, :minor), 0.125, release: 0.1
play (chord_invert (chord :A3, "M"), 0)
sleep 0.5
play (chord_invert (chord :A3, "M"), 1)
sleep 0.5
play (chord_invert (chord :A3, "M"), 2)
sleep 0.5

define :chordinvert do |tonic,name,iseq,timeseq|
  i=0
  while  i<iseq.length
    puts i
    puts tonic,name,timeseq[i],iseq[i]
    puts tonic.intern
    play (chord_invert (chord tonic.intern,name),
          iseq[i])
    sleep timeseq[i]*xx
    i+=1
  end
end

tonic and name specify the chord

iseq is an array of integers 0,1,or 2 that specify the inversion number

timeseq is an array of floats that specify the time each iseq inversion of the chord is to play

the arrays iseq and timeseq must contain an equal number of elements.

The program plays a song using the chord inversion sequences.
