 Straight tone holes are much more prevalent, but rolled tone holes are favored by some saxophonists as they supposedly produce a different timbre of sound.An American company based in Elkhart, Indiana named "Martin" manufactured saxophones with straight toneholes that were tapered, i.e.the circumference of the tone-hole chimneys was smaller at the point of contact with the leather pads than where they were soldered to the main body of the instrument.
