# Welcome to Sonic Pi
# Step 1: Choose Chords
chords = [(chord :c, '7-9').take(3),
          (chord :D, :minor),
          (chord :E, :minor),
          (chord :F, :major)]

# Step 2: Create and Rearrange Matrix
notes_matrix = chords.map { |chord| chord.to_a }
min_distance_matrix = notes_matrix.transpose.map { |column| column.permutation.to_a.min_by { |perm| perm.each_cons(2).sum { |a, b| (a - b).abs } } }
rearranged_matrix = min_distance_matrix.transpose

# Step 3: Live Loop Rendering
live_loop :chord_sequence do
  use_octave -2
  with_fx :reverb, mix: 0.5 do
    rearranged_matrix.each do |row|
      synth :beep, note: row.first, release: 0.125, attack: 0.2
      sleep 0.5
    end
  end
end

# Step 4: Articulation with LFO Modulation
live_loop :articulated_sequence do
  with_fx :level, amp: 1.5 do
    rearranged_matrix.each do |row|
      lfo_value = Math.sin(2 * Math::PI * 0.25 * tick)
      volume = 0.8 + (lfo_value * 0.2) # Modulating volume with LFO
      2.times do
        synth :pluck, note: row.first, release: 0.8, amp: volume
        sleep 0.5
      end
    end
  end
