The JodyJazz DV Series Baritone Saxophone Mouthpiece combines knowledge from the past with proven innovations. The use of Golden Section Proportions, or Phi Proportions, between the facing, bore, and chamber are used to create an efficient mouthpiece with more harmonics and increased projection. These same proportions are found in the Stradivarius violins, Nautilus shell, and Egyptian Pyramids. This mouthpiece comes with Theo Wanne's innovative cap, ligature and pouch. Proven innovations like a secondary window and new facing curve have been adapted from the popular alto and tenor DV mouthpieces to the baritone. The secondary window allows sound waves to hit the vibrating reed and blast through the horn like a moving baseball being hit by a bat for a home run. The new facing design creates a reed with no dead spots resulting in an equal response throughout all registers. A big, broad tone with both an easy low range and amazing altissimo are also a benefit of the new facing. JodyJazz finds saxophonists that prefer a little brighter tone over traditional jazz mouthpieces like the DV most. Since the DV has a little more curve to the facing than usual, a slightly harder reed should be used. Harder reeds have an increased reed life and make playing in the altissimo easier.
