Lesson 2-1-23 - High C Natural
High C natural is one of the few high notes that has different fingering to its low note equivalent
I make this note by half-holing the top hole, and blowing very hard into the whistle.
With the half-holing, it's best to grip the top edge of the hole very hard with the left index finger.
The main problem with this note is finding enough air for it, as the fingering technique means you have quite a bit of a breath window once you hit the note, and escaped air is less of an issue.
