ASCAP created the dial-up ACE System in 1993 as a useful tool for music professionals. It was a well-received industry innovation then, and now we are extremely proud to make an enhanced World Wide Web version of this Database available.

The information contained in the Repertoire gives users the ability to search BMI information based on song title, writer name, artist/performer or publisher name.

Each screen within the Repertoire will provide you with a User Guide button. The FAQ button transfers you to these instructions.
