I've recently started recording myself and putting the audio on audacity. A while ago a classmate talk a bit about how he looked at the sound waves to help him figure out his sound and resonance. I'm curious if anyone else does this and has any suggestions on what I should be looking/listening for with these sound waves. I play the tuba in college and right now I have been looking for "blocks" or smooth waves and not sure if this is correct or not.

Thank you!
