Good man, CC, for putting this up. Not bad at all for, what, 2 weeks playing.
This tune is a bit tricky as a first choice, because it's not "pure" trad, and settings tend to be influenced by Brian's style (supposedly, it's the first tune he wrote). I learned it directly from Brian himself, but I play it fairly straight. OK, here's some critique.
o You're playing too fast for what you can handle. You start around 134 bpm and end up around 120 at the end. Instead, try around 116 and keep it rock-steady.
o By consistently playing high f3 instead of F3 in the in the repeated figure |GBd G3|FAd F3| you're missing a basic melody of the tune. The second half is an "echo" of the first, like call and response. Kicking that G3 or F3 up an octave should be used sparingly only as a dramatic variation.
o It sounds like you're following
this TheSession transription the last time through in bar 12. But that's likely a transcription mistake or somebody's odd variation, and seems off to me in a basic setting. The "echo" of bars 11 and 12 is important. Don't be a notation victim.
o It's not surprising you need to work on your rolls. They sound like classical turns, and shouldn't. You're shooting for:
Ace aed|cdB A(blip)(blip)|GBd G(blip)(blip)|FAd F(blip)(blip)|
The cuts and taps need to be so quick that you don't hear the pitch of the notes, only blips. And don't use T2 to cut/roll the A, use T1 instead. T3 is fine and normal to cut/roll G and F, but you can try T1 there, too (which is what Brian tends to do).
o Think about your breath points. You're breaking every 4 bars in the A part, which gives a very square feel. Don't be so influenced by the written bars, and keep the flow going. Eskin's video gives one example of how to avoid "bar line syndrome".
o It's good that you're avoiding tonguing for now. But this tune actually tolerates a good bit of tongue articulation. You might want to experiment, with more of a dance feel in mind. On the other hand, try starting phrases (after a breath) with just a breath push instead of always tonguing them.
o You're tending to approach notes from below. That's OK and legit, but shouldn't be primary at this stage. It can also give an unpleasant "slidey" feel. Think cuts instead of taps as note separators, and avoid up-slides for now. Shoot for nice clean fingering and solid pitches.
o If you want to play around with phrasing, think about the first phrase, and the difference between:
Ace aed cdB A3 => Acea edc dBA3
A lot to think about, but I hope some of that helps. Keep it up!
