So I've recently been practicing my left hand technique and trying to improve my economy of motion. One useful tip I've found is to keep the left hand fingers down after fretting the notes instead of lifting them after each note is played when ascending. This cuts back on unnecessary motions. My question is regarding decending runs. Do you fret all the notes at once and then lift each finger off as you play the note or do you play a note , lift finger, then drop next finger on the next note. Ex: if you were to play a run on the high e string from A to G to F# to E. would you put all three fingers down in one motion then release as each note is played? Or would you play A with say the 3rd finger then lift then drop the 2nd on the g? A little hard to explain but maybe someone here will know what I'm talking about.
