This may seem like a stupid question, I don't know. But, when playing a song (like Plug in Baby - Muse) that uses the same fret but on different string in quite quick succession, how would I go about pulling that off with my hand? At the moment I'm putting my middle finger on the D and index on the E and moving my Index down to A when it's time to play on that, but my hand is in a really awkward + uncomfortable position, so, what else could I do to play this? I tried to use just one finger and moving it up and down but I cant pull it off properly.
