About the International Society of Bassists

The ISB was founded by the world-renowned virtuoso Gary Karr in 1967. With some 3,000 members in over 40 countries, the ISB is an organization for those who teach, study, play, repair, build and enjoy the double bass. The ISB is a forum for communication among bassists throughout the world and across a wide variety of musical styles. Members receive our journal, Bass World, three times per year and are the first to receive email communications regarding upcoming events, bass news, and more. Every two years the ISB holds an international convention and double bass competition, a composition contest, and now, a makers competition. If you love the double bass, become a member of the International Society of Bassists today!

When I first started coming to ISB conventions back in 1999, it was overwhelming in the best way! I saw performances that exceeded my wildest expectations, such creativity in repertoire, excellence in teaching, and of course the camaraderie is incredible . . . .
