I thought I had read somewhere that Willie Clancy was of the opinion that the core sound of the pipes was the chanter heard over the drones… I can’t find the actual quote at the moment.
When I started piping, in the 1970s, I was listening to hours of Paddy Moloney playing with The Chieftans and hours of Paddy Keenan playing with The Bothy Band, without any regs to be heard at all. And only rare use of the drones.
Yes I agree that oftentimes the regulators are used in a way that doesn’t make much musical sense… such as in a piper playing through a tune three times, and just hitting a couple chords on the regs the 3rd time through the 1st part, only. Such use sounds random and arbitrary, no matter how good the piper might be at playing the chanter.
Then there are pipers who use the regs in a consistent musical way. There’s an old 78 from c1920, I can’t remember the piper’s name, where the piper uses his regs as part of his overall arrangement of the tune: no regs in the first part, then the regs come in in the 2nd part and support the tune in a very effective way, the reg arrangement being the same for all three playings of the tune.
I really like those old records of Finbar Furey where the regs are an ever-present element of the pipe’s sound.
Of course Patsy Touhey used the regs to great effect, their use cleverly planned to fully utilize all the capabilities of the instrument for maximum public appeal. Also in this vein is Joe McKenna’s approach (such as when he plays an entire polka on the regs alone, or hits reg notes with the bottom of his chanter, etc etc).
As people have said, there are pipers who have elevated the use of regs in airs to a supreme art such as Ronan Browne, Mick O Brien, Paddy Kennan, etc.
I guess what I’m saying is: if you haven’t heard reg playing that appeals to you, keep listening to more piping! Soon enough you will hear reg playing that very much appeals to you.
