We can tell by the number of posts on the topic of tone (and by listening at sessions) that it’s hard for new players of the Irish flute to find the dark, centred tone which features on the recordings that attracted them to the music. Possibly doubly hard for experienced Boehm flute players, whose previous training has lead them in quite a different direction. I wondered if this would be a useful exercise …
Step One - discover the difference. Play a “nice” low octave G note, aiming the jet of air at the far edge of the hole. Now play a dark version of the same note, by protruding the upper lip (or withdrawing the lower lip, or doing both) to cover more of the hole, and to direct the airstream downwards, and by increasing the airflow. You should feel as if you were trying to blow a fly off your chin, or blow the jet into the centre of the flute rather than the edge. You should hear the note go hard and dark.
(Interesting to watch the spectrum of the note on an FFT spectrum analyser while doing this - you’ll see increased content in the 2nd, 3rd and higher harmonics. The Autotuner incorporates an FFT unit and is free to download - see my Resources for Irish Flute players page for details).
Step Two - Increase the difference. Now alternate the two notes, “nice” and “dark”, pushing the dark one harder and harder (both in terms of depression of the jet towards the floor and in increased airflow), until you are really impressed with the two differing sounds you can make. The “dark” sound should sound like tearing roofing iron compared to the cooing-of-doves “nice” sound. (Note - you may never wish to use the cooing-of-doves “nice” sound, but it has an important purpose here - to provide a reference from which you are trying to get away.)
Step Three - Increase the range. Now play up and down the low octave - firstly a few notes, then the whole octave - in both “nice” and “dark” modes. Keep pushing the “dark” darker.
Step four - Try some music. Nothing fast - we’re working on tone here, not dexterity. If you play fast music, you won’t have time to make the little adjustments needed to optimise each note. And you wont have time to evaluate the tone colour of each note. A song tune, an air, something with long notes, or just noodle. Use both modes (“nice” and “dark”) to confirm your progress.
Step Five - Real Life. Try some dance music now, and see if this exercise has helped darken up your tone. Again use both modes to explore the difference.
I’ll be interested in feedback to see if this approach has merit as an introduction to Irish tone, or if it might have merit but needs further clarification.
