This document discusses how the BAND app can help music directors more efficiently communicate with students and parents. It outlines how the app allows directors to post announcements, schedules, videos, files and other resources in one central place. This helps address issues with email communication getting ignored, lost in spam folders or relying on multiple modes of contact. The app also enables two-way communication through chat and polls to gather feedback, without needing to exchange personal contact details. Examples are given of how the app was used to coordinate a large field trip with multiple performing groups. Tips are provided on setting up a band on the app and encouraging its use.
