Hi all. First time poster here. I sing for fun, am not formally trained, and I'm not well-versed in singing jargon; but people say they like my voice, and I enjoy singing.
I noticed that when I sing on the mic, my voice starts to break on high notes when I belt, but when I'm off the mic and without music accompaniment, I can sustain those notes and belt higher.
For example, as I sang in the chorus of "A Whole New World" on a mic, I was able to belt the first line well, but I feel winded and have no power left for the second line.
After I went home, I tried singing the same song and was able to fully sing the whole chorus without much trouble. Though my throat does feel tired, I'm able to better manage it when there is no mic.
What could be happening, or what might be the factors contributing to this? If I wanted to address this problem, do I just have to keep practicing on a mic and get used to it?
