[Harp-L] Re: Hole spacing on different harps (Was Seydel Blues Favorite)

[Don Whitener <whitener@xxxxxxxxxx>]

Zig,

Thank you very much for taking these measurements.  This answers my 
questions nicely.  Unfortunately, the questions you raised were not 
that simple :-) I have no first hand knowledge on the physics 
involved, but I have observed as one poster mentioned that harps seem 
more responsive if the reeds are closer to front edge of the 
plate.  However, that surely must be a secondary consideration to 
proper gapping.  Maybe the answers will turn up.

Regards,
CDon
