lets say i am going from C-D-E-G to D-E-G-A...to play note D i have to use the 3rd finger for both Ds...while doing this i have to find a pivot(which is the E on higher string) on the higher string to go back to the lower string, but this creates a bit of sound which should not be there. i am guessing the solution is to mute the higher E(in this case) by using the right hand finger or soft pressure release on the left hand finger pressing the E...is any of the approaches correct or is there a better way to sound clean? am i doing it completely wrong? i donot want to go on practicing wrong 'things'...please advise on what would be appropriate.
much in need of help and the same will make a huge difference to my understanding so thanks for any contribution.
