I think the essence of accompaniment of dance tunes is that it is just that.
So many guitar accompanists do not grasp that they are only there to add rhythm to the melody, not to distract from it.

Exotic chords and syncopation may have an occasional novelty value (although probably not in an actual dance setting!) but a sympathetic guitarist, pianist or whatever knows this principle and applies it.

Virtuosos and egotists should keep well away unless they accept this- otherwise they are a damn nuisance as accompanists.
