I m very interested by creating a Paddy richter slide diatonic 10 holes by using the switch harp!
Do you think that it might work
I want one in G and one in D
Could you confirm my theory
Buying one switch harp and 4 harps
One in G and retune the 3 blow and the second harp is a A wich retune to fill the G major scale
And doing the same with a D harp and a E harp?
Is it all right? Will the sound and the airtigh will be good?
Does it will be like the old Paddy richter slide diatonic 10 hole?
To make the G slide diatonic (SD), you just raise 3B on the G harp one full step from standard Richter, and the modification of the A harp isn't too difficult either:
Code: Select all
Difference in half steps: 0 -1 +2 0 -1 0 0 -1 0 0 New SD blow notes: a c f# a c e a c e a Original blow notes: a c# e a c# e a c# e a Hole: 1 2 3 4 5 6 7 8 9 10 Original draw notes: b e g b d f# g# b d f# New SD draw notes: b e g b d f# g b d f# Difference in half steps: 0 0 0 0 0 0 -1 0 0 0
The finished tuning looks like this:
Code: Select all
Blow: Slide in: a c f# a c e a c e a Slide out: g b e g b d g b d g 1 2 3 4 5 6 7 8 9 10 Draw: Slide out: a d f# a c e f# a c e Slide in: b e g b d f# g b d f#
On the D version: high key Switch-Harps suffer from the dreaded Helmholtz Resonance Coupling phenomenon, which makes the upper octave reeds go significantly flat. If you're playing in the lower two octaves it will be fine, but if you want to use the upper octave you'll need to tune reeds higher to compensate.
I have done a video on it, see the Switch-Harp page:

Most Irish tunes don't go above the B note on hole 6 draw of a D harp, so it's not a big deal for your purposes.
