Mark Sarnecki's comprehensive approach to music theory gives students of all levels the tools they need to become well-rounded musicians. Each book in these progressive series includes clear and concise lessons, using language appropriate for students at each stage of their development. Helpful diagrams and images accompany each lesson and combine with a variety of engaging learning activities to reinforce essential skills and knowledge. For late-intermediate to advanced level students, this three-volume series clearly presents elements of harmony, voice-leading, melody writing, and structural analysis and organizes concepts into three progressive levels. The Advancedlevel addresses modal mixture and borrowed chords; the Neapolitan chord; augmented 6th chords; chromatically altered chords; common-tone chords; chords related by a chromatic 3rd; modulation; composition; the Bach Chorales; and counterpoint.
