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



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

Don, I pulled out all my harps to compare and that is an absolutely correct observation: both of the two Seydels do stretch the 10 holes out slightly wider(7.75 cm) than Hohner( 7.2 cm), Hering (7.2 cm), or Oskar ( 7.3 cm).

Now you've got me wondering whether responsiveness of a harp as far as bending/overblows is at all related to comb thickness or reedplate thickness, as the Favorite seems so easy and the thicker combed harps(Oskars and the Sessions) traditionally are poor , squaking overblowers. (or is it reed material, length to width ratios etc). I call for a scientific investigation!
