Just a quick update.
I have been working hard on this for the last few days. Unfortunately, I feel like my playing is going backwards rather than forwards
I think there are several different issues that I need to break down and focus on individually:
1 - the resting hand/pick orientation.
My natural position is quite supinated with a heavily DWPS orientation. Moving to a neutral resting position (both hand and pick) is easy and comfortable. Even moving beyond this to a pronated UWPS position is easy and comfortable.
I can handle each of the orientations and changing between them at reasonably quick tempos on one string around the middle of the guitar. It is still reasonably easy on the 1st and 2nd strings. However, I find this orientation awkward on the 5th and 6th strings.
2- picking motion
in my natural resting position I seem to use a predominantly forearm rotation movement. for UWPS. However, in the more neutral position it seems necessary to use a wrist deviation movement. This is fairly easy and relaxed up until around 150bpm and could probably get beyond this in a more relaxed fashion with practice. However, I seem to be having a few issues with the neutral orientation and deviated mechanic. Firstly, it is more difficult to get the pick to full clear the string on the upstroke. Therefore, I catch more strings accidentally. However, I think I can be improve this with practice. Secondly, I seem to use very different muscles for the wrist deviation mechanic. I notice more tension in my back, shoulder, bicep and elbow when compared to the relaxed (still fairly relaxed even at 16th note 200bpm) forearm rotation movement. I have been feeling little tennis elbow over the last few days although I can’t be sure this is caused by the picking movement as I have been doing other things which can aggravate this too.
3 - UWPS. I have been working on one way UWPS for several months. I usually spend some time each night doing things like the Gilbert overlapping 6 lick. It is never as fast a my DWPS playing but can hit 16th triplet at 110+ with minimal problem most nights. It is definitely stiffer and less relaxed than DWPS though.
4 - starting with an upstroke. I have read many discussions on this and Troy’s comments too. I have no problem mechanically starting a phrase on an upstroke. I do this regularly with syncopated phrases that start on an offbeat. However, I struggle rhythmically when starting a phrase on the beat with an upstroke. I understand the benefits of being able to do either but I have always found that knowing where the downbeat is with a downstroke is a real benefit to being able to play smoothly and in time. I’m not sure my head is ready to deal with offbeat upstroke phrases
I’m going to persevere for a few more days then shoot some new video to assess how things are progressing.
Thanks for your input so far.
