I wonder if this might be of some help. I wrote it about the flute, not the whistle but I think the principles are probably the same. Anyway take it on board and see if it helps.
(It’s a shame that when I wrote it, so many years ago, I didn’t get around to putting the “slurps” into the second part of the tune. But hopefully by then you’ve got the idea.)
Out on the waterfront at Batemans Bay this morning with my box-player friend. Passers by sometimes ask do I ever stop for breath? The answer is no. I never run out of air!
Breathing
There is a great temptation, especially among music notation readers, to breathe only at the end of parts of the tune. This usually means that a lot of the tune is played weakly for want of air, that breaths are long and loud and that parts of the tune get lost. Experienced players find smart places to breathe often, and turn the pauses for breath into punctuation. Smart places include long notes, which might otherwise be rolled. So, for example, a long G might be played as G…G, or rolled as GBGF#GGG, or used as a place to breath as GslurpG. In this way the need to breathe is turned into a virtue and the breath, instead of becoming a hole in the tune, becomes a statement, a rhythmical variation. Varying where the breath is taken can also add variety.
A good tune to try out some of these tricks is The Leitrim Fancy. Keep in mind that jigs should have a happy skipping rhythm (each bar will sound “tick-e-ty, tick-e-ty”). Rendered into “FluteSpeak”, the Leitrim Fancy might sound like this:
G roll, F# roll | E slurp B, B cut A B |
G roll, F# roll | D slurp A, A cut F# D |
G roll, F# roll | E slurp B, B cut A B |
G cut B, d B G | A cut B G, F# cut E D |
(repeat first part)
G cut B , d B d | e roll , d B A |
G cut B , d B G | A cut B G , F# cut E D |
G cut B , d B d | E roll , d e f# |
g cut f# e, d B G | A B G , F# cut E D |
(repeat second part)
