Musical experience is desirable, but you are also welcome without musical experience!
Differing musical levels and tastes increase the challenge of making and/or singing music together in a (small) group. Challenge promotes creativity!
Try out a different instrument than you are used to. Try a different genre than you usually sing. Feel more inspired by the natural environment and (weather) conditions than usually. Explore how you can get out musically with completely different people than those who seem easy or nice to you. Try a presentation at a different spot than you’re used to, like by or on the water or in the forest….
