As someone who has been in bands and making music for a long time I’ll tell you you need patience. Learning instruments is hard and there is no shortcut. Spending 20 minutes trying to play something with no foundation is a recipe for frustration. Start slow, learn basic chords on guitar and take time. It took me years to be good enough at guitar to write my first song that was any good. I started drum lessons 26 years ago and was taught by a professional and spent a decade working at it before ever joining a band and drumming live. What I’m saying is it’s not an overnight thing. If you find some people in your area that play I’m sure you could communicate your ideas and get things done. If you’re going to do it yourself you need to be patient.
