Isolate the various challenges of each skill and practise them in a row. Here Fintan focuses on keeping a stable left-hand frame by playing all the 1st and 4th finger notes in the scale of A Major in 1st, 2nd and 3rd positions.
Notice how in 3rd position the hand-frame changes from a perfect 4th to an augmented 4th and then how on the E string the frame returns to a perfect 4th but at a half-step lower.
