Zildjian Orchestral Gongs are the lead choice of the world's leading symphony orchestras, drum corps and rock stars alike. They are also great for use in wellness and therapy programs. These Chau-style gongs are a one-piece cast construction crafted in China with ancient traditions. When struck, Orchestral gongs produce rich, low dark tones with a complex blend of beautiful warm overtones and can roar with plenty of attack when necessary. Pre-drilled and corded.
