The New Orleans Jazz Styles series are written for pianists performing at the intermediate level. Gillock believed that every student’s musical education should include experiences in a variety of popular styles, including jazz, as a recurring phase of study. Performers are encouraged to deviate from the written notes with their own improvisations, for spontaneity is an essential ingredient of the jazz idiom. TITLES: New Orleans Nightfall • The Constant Bass • Mardi Gras • Dixieland Combo • Frankie and Johnny (Theme and Variations).
