If you’re a musician starting out or looking to gain a larger audience, a great place to get started is through social media.
Andrew Apanov of We Spin, Dotted Music and Stand Above the Noise shows you how to create and optimise your Twitter profile as a musician.

“Keep information on your Twitter profile up-to-date. When there is a new campaign (event, new record, music video etc.) – update your bio and Twitter header with an appropriate CTA and graphics.
For the Profile Photo, use your photo (head shot) where possible. A logo is a solid alternative.
You can create beautiful Twitter headers quickly and for free with Canva.
You can find the current Twitter (and other social networks) graphics specifications at this location.
A WeSpin formula for a great Twitter bio: Short Pitch (description of who you are in few words) + CTA (a call to action with a link) + Humor.
Pin the most important content on your Twitter profile (consider pinning a rich media tweet, e.g. attaching a photo, or a YouTube or Soundcloud URL).
Look at what bigger artists do on their Twitter profiles, but remember that their current goals are most probably different from yours.”
