I felt the same way in the Water Sanctuary Just keep trying...I'm not much help either but just keep doing it and practice. Also, use short bursts of breath, not long, drawn out ones. Hope that helps a little Good luck!
if you turn up the volume you can hear a metranome. you have to play with the beat, not just randomly. i havent played ST in a while. but i think the metranome plays in 4/4 time. i hope your a good musician
