Alfred Premier Piano, Lesson Book 6
By Dennis Alexander, Gayle Kowalchyk, E. L. Lancaster, Victoria McArthur, and Martha Mier
 
From the publisher (Alfred Music):
Premier Piano Course Level 6 lets students develop their rhythm skills using mixed meter. A special focus is a stylistic introduction to the Romantic and Contemporary masterworks, as well as popular music. Additional pieces range from lyrical ballads and jazz styles to arrangements of familiar classic and folk themes. New concepts introduced include diminished triads, the ii-V7-I chord progression, and additional scales and keys.
