Question:

How do i develop whistle register in my voice, and what exercises should i do ?

Best Answer - Chosen by Asker: i think you should drink a lot of plain water before you sing.then practice the middle range of your voice so that you can open you throat widely.don't try to hard to access the whistle register because it will make your vocal cord strained and unable to access those lofty notes such as C7 and higher.by the way you should drop your jaw down to the earth so that the whistle tone that you will produced is impressive.good luck and i hope that you will able to access the whistle tone to make you vocal range widen.bye.hisyam khalid.your friends at st joseph high school.
