Yes sorry for the rather silly screen name. I would change it if I knew how. It seemed appropriate at the time, as I was on a Holy Quest to obtain and play the bagpipes of every so-called “Celtic” land…
Anyhow my name is Richard…
Back to the fingerings, the fingerings I gave, where the ring finger of the lower hand is kept on the whistle for G, A, B, Cnat, and C#, is how all the players I observed happened to play when I was learning back in the 70’s. This helps make many passages easier, keeps the whistle anchored, and is in accord with the fingerings of the uilleann pipes (which is where this fingering approach may have originated).
In observing the “real Irish guys” play back then, and slavishly copying them, it dawned on me one day that the fingering approach, rather than being like the “open” fingerings of orchestral instruments, was more like the partially open fingerings of bagpipes, and in some ways like the chord shapes of the guitar.
Because with the fingering xoo oox you can move the lower index and middle fingers as one unit, and the upper middle and ring fingers as a second unit, and by moving only these two units play figures involving G Major chords with great speed and clarity. I call it the “G shape”.
The “D shape” as I call it is xxo xoo and many passages in reels, jigs, etc are played leaving that lower-hand index finger on, greatly decreasing the number of digits which have to be moved about, and thus increasing speed and clarity.
As I’ve said these “false” fingerings work just fine on the old D Generations, the only D whistle available back then, but often don’t work well on 21st century neo-whistles. Sad that traditional technique must be sacrificed due to the incursion of “improved” instruments.
