Blues style is definitely a good place to start, most modern music follows the blues pattern in one way or another. To be honest, most classical music utilizes the 1,4, 5 chord progression one way or another.(Fur Elise has an E A with a c/b Aminor run, Bach Jesu for mans desire is mostly g, c, d Beethoveen's 9th, G D, G, D, G d G D / D, G, D, G D C G I could go on, Tchaikovsky, Mozart, Wagner, Mendelssohn, Chopin, Brahms they all used the 1-5 which is by extension the 1-4, g is the 5th of c, c is the 4th of g that's the blues formula.) That's pretty much music 101. Jazz is a bit more complex, they say blues is watered down jazz. Rock, country, funk, soul, they all have blues roots. Rock will probably give you the next best mileage, that's what most bands play these days. As Grandpa used to say, he had a love hate relationship with Garth Brooks, on the one hand he put country back on the map, on the other hand, he turned country into rock. From there, why not try them all? Every genre has something to add, and if your playing in a band, they will probably play more than one style. If your playing in a cover band, playing a few hours, you will probably play some funk standards like Brick House, or Mr. Big Stuff. That's what gets people dancing, and believe me, you get a couple of pretty girls on the dance floor, your show is probably going to bring people in.
