I am having some troubles keeping my three not per string straight ascending scale playing clean. I use USX and a wrist + forearm motion. My playing has come a long way and i am very happy with my progress since joining CTC.
My main question and based on my own critique of my playing is that the ascending 3NPS scalar playing is a fretting hand / sync issue. I use scalar sweeping (economy picking) for ascending lines and i think the issue is that when i play the first note of each string with my index finger i leave it there until i play the third note on that string and only then do i move it. I think the fluid movement of the continued downstroke on the right hand is occuring a lot quicker than i can get my left index finger down to the next note on the next string.
For Example, naturally my index finger will remain planted on the 5th fret of the E string until after i play the 8th fret. Would it be more efficient / cleaner to move the index finger above the 5th fret on the A string once the middle finger has played the 7th fret so once the string change occurs it is more fluid / clean.
I have found this isn’t really discussed anywhere on any forums or videos on the internet i have come across (maybe that’s because its incredibly obvious) but i have found it interesting that i have only just noticed this now after playing for 15+ years.
TLDR; When playing scales do you plant your index finger until it is required again and then move it or do you begin to reposition it to the string/position it is required whilst your other fingers are still playing their required notes ?
