Question:

How do I develop head voice from falsetto?

I can reach Soprano hgih C in falsetto (shrill) but can't sing above F above Middle C without falsetto. How do I build up my upper range.

Best Answer - Chosen by Asker: I use to do slides down from my falsetto to my chest voice. At first there would be huge breaks, but over time they got smaller and less noticable. Then I started to slide up from the chest voice to the falsetto (much harder) till I got the same level of smoothness. Through out all of this, I also just worked on better breathing to strengthen my upper range.
