If playing by yourself just alternate playing part A then B then A
then B
If playing with someone else, one person plays part A through 1x, then
play both parts at the same time repeating each of your own parts.
Have fun with it (play part B and octave lower the first time, then an
octave higher the second time around, etc, etc.).
PART A (you can also play each note of the chords individually 1x
instead of playing the whole chord 3x on each line; if you do this,
add a -3'' before the +4 +5 in line 2)
+4 (+4+5+6) (+4+5+6) (+4+5+6)
-3'' (+4+5) (+4+5) (+4+5)
-4 (-4-5-6) (-4-5-6) (-4-5-6)
-2 (-2-3-4) (-2-3-4) (-2-3-4)
