Re: [Harp-L] overbend terms

[Winslow Yerxa <winslowyerxa@xxxxxxxxx>]

First, an overbend is a general term that refers to:
 
A reed moving away from its slot before springing back as a result of breath flow (opening reed action), producing a pitch higher than the pitch it produces when plucked or when sounded in the usual fashion, by moving into its slot before springing back (closing reed action).
 
However, the meaning is slightly more restricted. Opening reed action occurs during the standard two-reed bends that occur on unvalved diatonic harmonicas. For instance, when you play a 4 Draw bend, the draw reed bends down in pitch in standard closing mode, while the blow reed sounds the same pitch by opening. The opening blow reed, activated by a draw breath, produces the same result as an overdraw, but it not considered an overdraw as such, but rather as the responding-reed portion of a standard dual-reed bend.
 
Generally, the term overbend refers to opening reed action that occurs in a single reed in isolation. This works out in two ways:
 
-- Overblow, produced by a draw reed opening in response to a blow breath
 
-- Overdraw, produced by a blow reed opening in response to a draw breath
 
On a standard unvalved German Major tuned diatonic, overblows occur in Holes 1 through 6 (same holes that produce standard draw bends), while overdraws occur in Holes 7 through 10 (same holes as produce standard blow bends)

Subject: [Harp-L] overbend terms

I understand Draw Bend 1-2-3-4-6, and Blow Bend 8-9-10. (Major diatonic)

Can someone please link to the definitive meaning of

  - overblow
  - overbend
  - overdraw

(Would "definitive meaning" be a redundancy?)
