Find some friends with similar musical interests and form a band. Have weekly rehearsals in someone's basement/garage/studio, or cooperate to rent some rehearsal space.So... silly question: any hints on practicing live playing without actually playing live?
There's no way around it. You have to play with other people. Be patient but constant.
When you're not actually playing, practice your timing and coordination whenever you can... while watching TV, while listening to music in your car or public transport, while waiting in the doctor's office, etc. You can practice anywhere: on a table, on your legs, in the air. Do it until people ask you to stop, then keep doing it, with our without music (the music is in your head).
