About

By musicians, for musicians.

SinfoniaOne grew out of the frustration that running an association in wind music always means three Excel sheets, a WhatsApp chat and an old piece of software at the same time.

We're active musicians ourselves. Librarian, conductor, board member, plain member — we know every role because we play them.

SinfoniaOne should give the cue and step aside, so we can spend our time making music. Sounds simple. It isn't. That's exactly why we work on it every day.

What we care about

Mobile first
The member is in the rehearsal room with a phone in hand. Everything must be reachable in two taps.
One tool, not a module zoo
Score archive, marching book, appointments, tasks, members — they cleanly plug into each other.
Honest per-association pricing
Flat fee per association, not per head. Replacing your Excel doesn't get more expensive when you grow.
