Just joined to jammr. Playing bass guitar and guitar. Really don't know how it works, but I'd like to play with anyone. It will be new expierence for me. Can help with arrangment and recording then.

Hi jury,
Welcome to jammr!

The best time to play with others is Fridays, 18:00 UTC and Saturdays, 19:00 UTC. Those are the weekly jam session times where the community gets together and you will be able to meet other musicians.

But you can also play any time during the week - invite friends or announce a jam session on the forum:

Happy jamming!

Stefan
