I am afraid that, in my area (Panhandle of FL), there are FAR more working guitarists as singles than keyboard players. Perhaps, because of the number of full bands already working, when a club or restaurant only wants a solo, they are looking more for acoustic music or singer/songwriter type music, rather than a 'full band' sounding solo artist. The karaoke aspect makes many stay away from it.

It has been easier (and more rewarding) to book myself as a duo and up than as a solo. Admittedly, I am not working the old folks circuit, where arrangers get more work, most play country/folk, Buffett and tropical music 'round here, and the more, the merrier.

I got to feel sad for anyone that prefers solitary music-making just for the money. Keeping things fresh is, in the long run, far more satisfying and less likely to make you want to quit music and work in an office or sell real estate!

You MIGHT not make as much money, though most of the best-paid entertainers in my area play in bands, but you will stay loving music for longer.....
