At the end of the day you’re a musician first and a marketer second. It’s always okay to bring in some outside help, but knowing the most common marketing mistakes musicians make will help you set yourself above the crowd by embracing the new opportunities available to you for promoting your music.
Take lessons. Don’t just take a lesson 1 time, that would be like going to high school for 1 day. (Which I think I only did half of that)
I get it, lessons can be expensive. Can’t afford to pay for them? Then barter for it. Trade a service for a service.
Do whatever you need to do, just take lessons.
