Energy work and the human voice

[Orfeo]

Hi.

I'm a classical / opera singer (tenor).
I was wondering if i could use energy work to enhance my singing voice:
Especially to reach higher notes with full voice.
Maybe working on the throat chakra?
Also in some magic literature i encounter the term "Magical voice" I wonder if you could elaborate on that..
I already bought "Energy work" and started doing the exercises from the beginning...

Thanks
Rafael
