Hey, Just wanted to clarify something. My range is from low F# (Pedal F I am working on... note comes out, pretty horrid sounding) up to top line F. I can get the G out above that, but, if I do that twice, I cant do it anymore. Now, I practice for 25min, scales, arbans, some songs to learn as you play, etc. Now - after the 25 min... I take a break for 25min and then go back to it for another 25min. After the break however... If I try to play any song... none of my top space E or F notes will come out, the front of my mouth is all red. Do I keep playing on the lower notes that I can comfortably play OR am I supposed to only practice while I can hit my top notes, and once they become wrecked... stop playing? Also, why am I able to play as long as I dont stop, but after my break, when I come back to it, its like everything has fallen apart?
