I’m a beginner of a few months, but here are my experiences:
I’ve stopped listening to any music except ITM, and I listen to it at least several hours a day. I’m trying to get an internal repetoire of tunes so that I can recognize them when I hear them, and can reproduce them vocally. Without that, how do I know that I’m playing ITM, rather than just noodling? I’ve found the local slow session, but have not made the time to get out there. I can only imagine that would do a world of good!
In addition to practicing playing the whistle, I’ll practice listening. I take a recording that I want to learn, play it on repeat and sing along until I can sing it smooth and precise. I currently using session recordings from comhaltas, and like them because they aren’t whistle recordings. I have to learn the tune and envision in my head how it will sound on the whistle. I break it down in my head into 2 and 4 bar phrases and make sure that I can clearly sing those. I make sure that I am hearing and able to sing a clear transition between the phrases (rather than just mumbling out two or three connecting notes as I slack through the repeat). I usually do this at normal speed, so I get the feel and essence of the tune, not just the mechanics. I find myself humming tunes all the time, even when not listening to tunes.
Once I am able to sing it with confidence, including transitions, WITHOUT the recording, I’ll pick up my whistle and try to play it. I still need to noodle it out, but by doing all this listening first, I’m spending about an hour to noodle out a tune, rather than the week it took me to memorize my first piece via sheet music. Additionally, I find that I can remember what note I’m trying to noodling, and don’t have to keep starting from the beginning.
Interesting (to me), I find that I start with an overly simplified version of the tune. My first run though of a jig will have a lot of repeated triplets… then after a few plays, that gets shaped into a little run or a turn. As has been mentioned elsewhere, the tune is stored in my head as sound.. not as finger positions or notation of some kind… so I don’t have to worry about being able to translate fast enough to make it come out right. My tunes start at about double the speed I could play them when learning from sheet music, with much better lilt.
I have taken to playing with a metronome at times, but not learning with it. I imagine the metronome being the pace of the rest of the session… I think that it makes sense to be ABLE to play with a rocksteady beat, so that any variations of tempo are intentional. I also think it gives great feedback for those areas where you are playing faster than your ability allows. If you suddenly slow down at a hard part, you should have played the tune slower to start with.
It feels a little obsessive, but in a good way. I’m always thinking about tunes and trying to immerse myself in the music. I find it is very fun and if I had extra hours in the day, I would keep doing more of the same.
