The fiddler has a point. A good bass line helps the fiddler imeasurably which can be played on the bass notes of the guitar.

An unsolicited tip..(wondering whether I should be doing this)..to change barre chords quickly, place the barre finger down first and the the finger that's closest to the thickest bass string next followed by the others consecutively.

Ie: Using the E chord position, start with the barre, then the ring finger, then, the middle and finally the first. In this manner, it pins your wrist into position and eventually enables you to move all fingers simultaneously and quickly.
