Hello, i am teenager boy. I do have an interest in singing, and I do sing alot! I also get complimented a lot that i got a beautiful voice. But there is a big problem no one realizes except me, myself. I got a sharp/heavy tone in high/medium notes and a light voice in low notes like that of ATIF ASLAM (Pakistani singer). Everyday when i wake up, my voice is fresh, crispy and capable of reaching any high note. When i go to school, its like that for the first 2-3 periods, but then the voice starts changing, it becomes flat, and it feels my voice is blocked and I LITERALLY can't sing any medium or high notes (even my low notes becomes worse). It stays like that and throughout the the school timing and it becomes worse on the timezone when school overs. Even my speaking voice loses its sharpness and i sound like an annoying 5 year old. I know that sharpness in the voice at the morning is because of the those acids after you wake up but MY voice is NOT like what it changes to at school. Its usually fine in most cases when at home alone, but why does my voice literally becomes so trash as time passes in school. is it because i talk alot in the school? i tried not talking much, as much as it is possible to NOT talk in school, and it delayed the time when my voice starts to get worse, but it doesnt stop it. When i come home after school, the voice stays like that for a while until at night around 9Pm my voice starts to get its sharpness back. Sometimes, it doesn't, so i have to drink honey in warm water for it to be fixed, and sometimes even that honey drink doesnt work!! how do i maintain my real, sharp voice. HOW DO i keep it when i need it the most (afternoon in school, because of singing competitions etc). Is there a different procedure to maintain a sharp voice, if so, please help me with my case. It's getting depressing day by day!!
