How can I get a higher voice and how much higher? r?

I don't get all the paino stuff there, but I hope I can help anyway. Try warming up like this; long, hard loud shushing like shhhhh using all of your breath as hard as you can can help strengthen your voice. Then to develop range, try singing a steady ahhhhh in a low-ish chest voice into a middle bridge (keep that steadily going higher) into a head voice as high as you can, the. Back down to as low as you can. Doing this over a period of time (a few months maybe) and you will notice the difference. You will be able to sing a much higher/lower range and your voice will be a lot stronger in your lowest chest/head voices.

I can prove this works fast because I'm a thirteen and last year...I couldn't reach my head voice. (which is bad because I'm a girl) Now I can go to some of the highest notes in bead voice at ease. Also advice: don't rush. In my experience, time works best.

Again, hope I can help =)
