There is some ambiguity as to whether real trumpets or the Yamaha GX-1 was used for the introductory trumpet part. Anecdotal evidence"The intro horn is definitely a Yamaha GX1, as are all of the synth sounds used on Fanfare for the Common Man. Keith used three registrations (patches,) the intro horn, the brass like poly synth lead, and a modulated organ-like lead; I believe that that synth bass sound was simply the lower octaves of the organ-like patch. The Moog was not used at all, except occasionally on extended live versions that formed a finale. I know this because I discussed it with Keith and his keyboard engineer, Will Alexander when I met with them a couple of years ago." suggests it was the GX-1. When performed on some of the Works Live tour, Fanfare began and ended with real trumpets but the liner notes for the album Works Volume I show only the three band members and no other performers on that track.
