Musical styles are given different names for the Casio SA-76 and Kawasaki  keyboards. Styles are called patterns for the Casio keyboard. Based on the owner's manual definition for the Yamaha E463, styles is a feature dealing with rhythm, bass and chords. Press the "styles" button on the Yamaha keyboard for a list of styles with numbers ranging from 001 to 235. Regarding the Kawasaki, there are rhythm style buttons only. No bass or chords. Just a whole lot of fun learning different instrument sounds with eight rhythm choices and a button for drums while playing or recording. There is a song book for the Casio SA-70 for nine pre-recorded songs. There are demo songs for the Kawasaki, but no song book (to the best of my knowledge). Thank you for watching.
