Nose - How To Control It, Part 2 (opening and closing at will)
Now your goal is to open and close your nose in middle of your breath stream.
Again, start with a deep breath and play a single blow note on the harmonica with your nose closed. After two seconds open it (thinking as if you're blowing your nose) while the note continues to sustain and feeling your bellybutton go to your spine to use your diaphragm to help get rid of air. Close your nose after two seconds, stopping the air from leaking through your nose so that air is only traveling through your harmonica.
You'll probably only be able to do: closed, open, closed, open, and then you'll be out of air.
Once you can do this well, perform the same exercises inhaling.
More next week. Have a great weekend!
