When I warm up before I start to practice scales and then eventually play some peices I`m working on I usually do like this:
When ever I play scales I use rest strokes to get more resistance and to use more force\strength in relation to the finger.
I play them mainly (for now) using the i-m combination.
However I hold my hand in a near 80 degree angle when I do the rest strokes and the i-m method is not hard to do it is ok.
Though when I practice on pieces after this and if there are 2 successive notes on one string I only use one finger to play them both, not the i-m as in the scale, mainly couse I can`t play using the PIMA in the hand position I use when practicing scales.
Is it common to do this or do most classical players i-m on the same string?
Just wonder couse maybe my angle is a little bit to small on my picking hand then.
I know there is not a "standard" but as in most useful technique and progress it is nice to know still
