Baroque Guitars are NOT "ten-string guitars"
Andrew, frankly, you are mistaken. It is incorrect to refer to a baroque guitar as a "ten-string guitar". No one refers to the baroque lute as "the 24-string lute", but correctly as the 13-course lute. This is a well-established musicological/organological convention. "12-string guitar" is the only exception to this, and that is only because the term has been disseminated by the popular "cult(ure)" in the usual brainwashed ignorance of the masses. If two strings function as one string, they are a COURSE, not two separate strings. In contrast, a ten-stringed guitar has ten separate strings each of which can be separately fretted. This is not the case on the baroque guitar, which effectively only has five courses. Moreover, the term "ten-string" guitar has come to signify a particular instrument, which is NOT a baroque guitar. You are evidently not a musicologist/organologist/semiologist/semantician so I don't see what you think you will achieve by being bothersome about this issue, which relates to organology and semantics.
