In a recent TC, Tommo has suggested I improve my hand synchronization by really focusing on single string work. Has anyone broken down “chunks” into even smaller chunks and gained speed and precision this way? For example, the “Yngwie Sixes”: It’s 16th note triplets on the high E, 13-10-12-13-12-10, repeated. Doing them continually, I start to get sloppy at about 120bpm-125bpm. However, I discovered that if I break it down to where I’m doing the sextuplet runs on beats 1 and 3 and just hitting “13” on beats 2 and 4, I can get to about 150 bpm cleanly before it starts to fall apart. Does anyone know if this is a productive way to supplement the “continuous” method? Or is it just my ego taking over? Thanks in advance to any who can offer perspective.
@SomeAverageJoe Sounds like you described a “burst”, in this case, 4 notes? Yeah it’s worked great for me.
Maybe that could work, but what I’d probably do is look at the individual components of the Yngwie pattern and repeat those. Meaning, there’s an ascending part (index ring pinky, or index middle ring) and a descending part (pinky ring index, or ring middle index). I think a lot of people who have trouble with the Yngiwe pattern are weaker with one of those over the other, and practicing them both as repeating 3 note figures can help.
I think of it as 7 note “bursts” (13-10-12-13-10-12-13) but yeah I suppose it makes sense to call it that. Glad to hear it’s had positive effects. Do you have any advice on how to transition from this to a more continuous “phrase”?
It depends! Can you comfortably tremolo sextuplets at 120bpm-125bpm? 
Bursts can be useful if you have an efficient motion capable of the speeds you’re trying to play but in my opinion they’re a waste of time if your tremolo is capping out at a lower speed.
My old inefficient motion tremolo would max out at 110bpm sextuplets but I could do small bursts at 120bpm sextuplets, I actually have footage of this from when I was troubleshooting my motion on the forum 
Crappy old motion that can’t decide if it want’s to be wrist, wrist/forearm or elbow:
Newer, efficient wrist/forearm motion (video from another forum post):
Let’s say it’s a phrase that’s 4 quarter notes long, ending on a 5th quarter note, of 16th notes. I chunk quarter note to quarter note in order to accent the downbeat; first 5 notes (first to second quarter note), then when that feels easy, 9 notes (first to third quarter note), etc.
If I finish the phrase but always stumble on a certain part, I attempt to isolate it by chunking that specific area. For example, in the situation above, if I was tripping up somewhere between the second and third quarter note, I’d practice those 5 notes until it felt smoother.
