Maybe it's just a psychological thing, but I've always enjoyed my own playing
more on narrow bore ("flat") chanters. I've played 'em in every key down to Bb,
and I notice a considerable difference in ease of expression. The sound of a
flat chanter (as long as it's in tune) is very expressive, and for some reason
it lends itself better to staccato playing, making a more bubbly sound. Some day
I hope to own a set in C. That there's my favorite flat key, because it has the
"older" tone of the flat sets, but it's sound still retains a lot of the bite of
the concert bore sets. And yes, flat chanters require a considerably smaller
amount of air pressure to operate correctly, and they are generally a bit more
stable than concert chanters. Isaac want! Grr!
However, I shall have to wait a while before I make any pipe purchases, seeing
as I just spent all my money on a used Patrick Olwell six-key flute! (and I'm
damn happy with it!) It seems to me that you have a choice between a full set or
a good flute. I'm just glad I got a deal on this one. But I'm rambling...
Slán go fóill.
