Don, if your point is that the guitar is as serious an instrument as the piano, I do not see any message to the contrary in this thread. Certainly not by me; I had a couple of "classical guitar" lessons myself (and more piano lessons; finger nails being the cause of conflict).

Fact is, there is a tradition of folk accompaniment characterized by chord names, and this is associated with the guitar and some free-reed instruments, but not the piano. (This must not be confused with chord names in jazz, meant for improvisation, similar to the figured bass in baroque music.) See the "ChordReq" threads on Mudcat.

My point is simply the following: using a piano, or a guitar in Segovia's style, sends a signal of "sophisticated" and/or "bourgeois" (not necessarily "serious"); performers should be aware of that.

Some performers manage to be sophisticated and still to sound simple and close-to-the-folks. For example, a well-led bass line is never out of place.
