Welcome to the Community! It's great to see you here.
Have a look around and get stuck in. There are lots of ways to start on the community but a good place to begin is by joining a group of people with similar interests to you. I would recommend checking out the Creatives Group (looked after by one of our Creative Associates Matt Ball), but you can also see the full list of groups here. There isn't a group specifically for musicians and singers at the moment, perhaps you could create one and invite other musicians to start networking there?
You can also Write a Blog Post to update community members of a project, or start debates and discussions; or add your Events and see what's on today in the arts in Wales in the What's On section.
As always, it's best to just dive in but do give me a shout if you have any questions, or check out the Getting Started Guide for hints and tips.
