Question
I'm currently working on an app which would help musicians collaborate schedule with each other easier then via email/phone etc.. Also for groups like Bands, Choirs etc.. But I'm having a hard time finding the right research about how many serious musicians are out there doing it for a living,
Where would you look as a start? I've tried searching for "band forums" "musician forums" etc.. But that doesn't help much
Answer
Subscription list from magazines such as "Keyboard", "Guitar", and so on. Subscription list from NAMM events. Partnerships with musical instrument manufacturers such as Roland, Yamaha, Fender.
