Welcome Alireza! It's nice to see new people joining the platform. I am sure that you will love it here as there is a large musician community on Steemit that supports one another.

You can join some contests as well to get new friends and build your network. Don't forget that the network is the most important on Steemit. It takes a lot of time and effort to get some rewards but if you become part of a community it will all go much easier for you.

I wish you all the luck and I'm looking forward to seeing you around!

Cheers!
