Premier Piano Course Masterworks Book 4 includes standard repertoire from the four stylistic periods to reinforce concepts introduced in Lesson Book 4. Except for Jazzy Trumpets," the pieces are in their original form and have not been adapted. Dynamics, phrasing, fingering, and pedal are editorial in some selections. The editors have also added titles to untitled pieces. Performance skills and musical understanding are enhanced through Premier Performer suggestions. Students will enjoy performing these pieces for family and friends in a formal recital or on special occasions."
