BDAA

BDAA is the companion app for the BDAA Convention — the annual gathering of musicians who play domra, balalaika, bayan, and the rest of the Slavic folk-instrument family. The community is multicultural: Russian, Ukrainian, Belarusian, and other traditions, all in one room.

Sign in with the email you registered with, and the app shows you what you came for:

— THE SCHEDULE. Every rehearsal, masterclass, concert, and meal in one place. Updates as the program evolves. Bookmark sessions and the app notifies you when their time or room changes.

— YOUR PART. Pick your instrument and the app shows the right sheet music for every piece. Open the score in full screen, pinch to zoom, flip pages with a swipe. New revisions arrive without you doing anything.

— REFERENCE AUDIO. Most pieces include a reference recording so you can practice along with how the conductor wants the piece to feel.

— ANNOUNCEMENTS. Quick messages from the organizers — "rehearsal moved to room B", "bus leaves at 9", "send your photos to this album". You get them as push notifications.

— OFFLINE. Once you've opened a piece, the score and audio are cached on your device. The app keeps working in concert halls with no signal.

The app is free, ad-free, and built for the convention by participants. We don't track you, don't show ads, and don't share your data with anyone outside what's needed to deliver email and push notifications. See the privacy policy for details.

To use the app you have to be registered for the convention. If you haven't registered yet, head to bdaa.org first — once you're on the participant roster, your email unlocks the app.
