Instruction to accompany 2:1 Breathing Audio at http://createsound.ie/resources/.
No voice and using melody cues for an extended relative exhale to stimulate the calming parasympathetic nervous system. Listen on headphones. When the melody goes 'up' - breath in... when the melody goes 'down' - breath out. The bass note in between breaths represents the short pause between in/out and out/in.
