May I somewhat tentatively offer a suggestion ?

If playing a guitar in standard tuning, and there is more than one of these in the session, it is worth knowing the barre chord positions for some of the more common keys.

Two guitars bashing out the same chords can be a little overpowering. If one of them plays an octave higher, or even ventures to pick out the individual notes in the barre chords, it adds some quite pleasing variety.

On most acoustic guitars, with the usual heavy strings, holding the barre chords for an entire tune or round or lengthy song can be hard work. But I think it worthwhile for a guitarist to add an individual descant line for even a single verse, (in my humble opinion).
