Response to reading Chapter 7 and 8 readings

Questions
1) How are they able to measure how many fluctuations per second they are singing for vibrato?

2) Does vibrato produce easier in lower or higher registers?

Comments
1) Now that I am taking private voice lessons I can better understand what I am reading. I just learned what a mixed voice was and how to achieve it so I feel like I can better relate.

2) I have never heard of female whistle register or stroh bass before so it was interesting to read about it!
