From above perspective it becomes clear that breathing has a much broader function
in music than singing or blowing a note, or producing a better tone resonance.
For optimum performance you must synchronise your breathing to the breathing pattern of the music, and when playing in a group all players should breath together regardless of their type of instrument.
The musical phrases of most popular, blues and Jazz songs are 4 bars long, and the end of each phrase is always a natural breathing point for the melody. This is where you must breath.
