Lyre

Lyre is a sheet music and live rehearsal companion app for marching bands, school music programs, and performing ensembles.

The app allows ensemble members to sign in, join an organization, access assigned sheet music libraries, download PDF music for offline use, view music by part, and follow along during live rehearsal or performance sessions led by a director. Directors and staff can manage organizations, libraries, parts, members, and live sessions through the Lyre web admin system. The iOS app is focused on the performer experience: viewing assigned music, staying synchronized with the current song during a live session, and accessing rehearsal materials on a mobile device.

For TestFlight review, the included test account has access to a sample organization and music library with test PDF content. Reviewers can sign in, open the organization, browse available libraries, select a part, view and download sheet music, and test the PDF viewer. If a live session is active, the app can also display the currently selected song and follow director-led changes.

Key features being tested:

* Lyre account sign-in and organization access
* Member profile and assigned part selection
* Music library browsing
* PDF sheet music viewing and offline downloads
* Live session follow mode for director-led rehearsals
* Basic account, organization, and library state handling

The app does not sell digital sheet music. Organizations are responsible for uploading and managing their own licensed or original music through the Lyre web admin system. Any sample music included for review is test content only.

This beta is intended for invited testers from music programs and internal development testers. The goal of this TestFlight build is to validate sign-in, organization access, music viewing, offline downloads, and live rehearsal synchronization before public release.
