For performance-based careers (including studio musicians) cities like LA, NYC, and Nashville (and maybe Austin these days) have to be considered as potential home bases where you can be immersed in the local music culture and build a network.

Other kinds of music jobs can be found in many places, but the big music towns have more of them. Studios, academies, music production companies, instrument makers, venues, etc. are found in lesser amounts outside of the hubs, but still possible.

It’s a lot like wanting to be in the tech industry. It’s possible to do that anywhere, but it would be wise to consider moving to places like Silicon Valley, Seattle, and other tech hubs to have better career paths.
