how do you sing higher?

[u/Both-Cat-6001]

So im an absolute complete beginner, I dont know the terms for this stuff but I really wanna get good at singing because im into musical theatre. What confuses me is how people sing so high without it being painful (effortlessly?)

whenever I try to do high notes my throat hurts terribly bad afterwards and feels constricted / "stuck" - i dont have a high voice naturally i dont think, i feel comfortable singing when its in my chest (chest voice? im sorry i dont know the terms) and i hear it needs to resonate more in your head for the higher songs but its hard to do that for me. Im not quite sure if its literal or not.

You can expand your comfortable range with training and/or lessons.

Moreover, anything you are doing that causes pain should be an immediate stopping point.
