[Harp-L] Blow sticks after overblow

[Ansel Barnum <Ansel.Barnum@xxxxxxx>]

Hi there overblow tech gurus--

Often after overblowing hole 5, I find that blow 5 subsequently sticks. 
This happens especially when I play the two notes in succession--ie, 
overblow 5 then blow 5. It doesn't appear to be a problem with the 
particular harp, as I've seen this behavior with both SP20s and Seydels, 
although I think it might be more prevalent in lower keys.

Any thoughts on what the cause and cure is?

Thanks,

Ansel
