Welcome to the official website of Ball State University's oldest active all male a cappella group, Note to Self. We are one of 5 a cappella groups on campus, one of two all male. Dating back to 2012, these men in purple are always excited about making music and having a great time. You can check out all of the current members, alumni, videos and pictures, music, important dates and merchandise through this site to get a real in depth look at Ball State's favorite men in purple!
