Today i discovered something new in my voice. I started to change my singing habits because i realized that i kept having too much discomfort on my neck when i sing high (starting around F4-C5). To fix this i decided to rotate my head in a circle while i sing, to release any tension on my neck. And it helped! it was so weird because i was able to sing the high notes with ease and no strain, although there were a few cracks on my voice, possibly due to growing strength? However, when i sing these high notes (f4-C5) they sound very strong and loud. I don't know if this is singing or i am just belting. is there a difference? How do i determine if i singing with too power from my diaphragm or if i am just belting? Thank you!
