[Harp-L] Inhaling through nose trouble, please help

[Michael Rubin <michaelrubinharmonica@xxxxxxxxx>]

It has come to my attention that inhaling through the nose while playing a
draw note will seriously impede one's ability to sustain that note for very
long.

I have a student who cannot seem to shut off his nose from inhaling.  When
he holds his nose with his fingers he can sustain a draw note for a very
long time.

How can you intentionally shut off the nose inhalation?
Thanks,
