Hey! Welcome to Steem! Yes the community here is tightnit and very supportive. As someone just arriving it may take some time to find your audience and “family” but I promise you will.
Going out and commenting on others posts (like this) is probably the best advice I could give as its how people find you. Another thing is to look at the “tribes” which are small niche communities that use specific tags and have their own tokens. A good way to browse them is through here - https://steempeak.com/tribes (you log in with the same username/key as Steemit.com, its just another front end).
Also many of the communities discuss and chat through the discord app as we don’t have a integrated chat option yet. Just a heads up.
I followed your account and look forward to seeing the music you share! Feel free to reach out if you have any questions.
