Fiscorn powerful baritone voice has no counterpart, (save perhaps the piston-valved marching baritone), in the organology. The forward-projected sound makes a pair of fiscorns the most suitable two instruments to join the shrill Catalan shawms (tenoras and tibles) and flabiol pipe, together with trumpets and trombone in the outdoor town-square setting where the cobla bands play for sardana dancers. While the instrument is often played by trombonists, its conical nature is easily mastered by tuba or euphonium players.
