I have discovered a great way to make sure your fingers dance efficiently up and down the neck of the guitar without any sliding or fudging about after placed in position:
merely slice the cushiony pad of one of them while cutting basil - though other herbs might work as well. (Try it at home and report back to me in the comments section. Experiment with fruit, too.)
Anyway, let me just say that I switched to some "creative" lyrics in "Esse seu Olhar" after switching from one inversion of an EMaj.7 to another.
