Developed in 1983 for jazz and popular music by Vandoren, these were the first of the Vandoren Java Green Alto Saxophone Reeds series. They are often referred to as Java Green, especially since the advent of the Java Red reeds. These are the originals, and are characterized by a thicker tip and a more flexible pallet. They allow vibration over a larger surface area with maximum elasticity. This type of vertebral column gives the musician much greater playing flexibility, as the elasticity zone is very large. Great for altissimo playing, as well as for anyone who seeks broad tonal color.
