YouTube Music Class: Yma Sumac

I found this great video illustrating Yma Sumac's otherworldly vocal range. Enjoy.

YouTube Music Class: high, low, whistle and falsetto

I haven't been in a formal music class in over twenty years, and lately YouTube has been serving as my surrogate. I really like this video of short clips of various artists hitting some really low notes, belted notes, falsetto (more about women and falsetto here), and whistle register.
