Welcome to the American Theatre Organ Society.

If you are one of our thousands of members, welcome back and enjoy our site. If you are new, we hope you will take some time to discover one of the music world's unique gems - the Mighty Theatre Organ. It's been more than 100 years since Wurlitzer, Barton, Robert-Morton, Kimball, and dozens of other companies created thousands of instruments, made to accompany silent films, and fill majestic movie palaces with glorious music. With 70 local chapters across the U.S. and around the world, ATOS promotes the instrument, presenting concerts and silent films, developing young artists and technicians, providing scholarships, and most of all, having a lot of fun in the world of music. If not a member, we hope you will join us. Welcome!
