When I sing my throat hurts not long after. I am pretty sure its due to me straining my voice when singing higher. The thing is I'm not necessarily singing out of my range but it happens when I sing in the higher end of my voice. What can I do to not tense or strain my voice as much when I sing?
warm up before you sing. yes, every time. yes, extensively.
Anfangen ist leicht, Beharren eine Kunst.
never try to sing high-end without good warm up. I tried this couple times... effect is similar to yours)
1) warm up.
2) sing in a key that's better for your voice.
3) practice more.
