What began as a conversation between two colleagues about music theory textbooks has grown into a leading music theory and aural skills curriculum. Clendinning and Marvin set out to write a textbook that puts the student musician at the center, using clear prose and interesting, accessible music examples to show students how the theory they are learning can be applied to their performance and understanding of the music. A strong pedagogical framework throughout the courseware reinforces core concepts and provides lots of opportunities for students to build and practice their theory skills, while coordinated workbook, anthology, and aural skills volumes provide you with a complete, integrated curriculum for your students. Highlights of this edition's new content: Two new chapters--Chapter 10: Analysis of World and Traditional Music I and Chapter 39: Analysis of World and Traditional Music II--introduce tools and topics for the study of traditional and world music to incorporate a broader perspective on music theory and expose students to a wider range of music. The new Norton Illumine Ebook engages students more fully in the material, placing audio clips next to every music example, incorporating interactives for key concepts, and using concept check questions to ensure students understand key material. The anthology of complete scores--previously available as a print supplement--is now available digitally and included with access to the textbook courseware so all students can benefit from the complete scores. The two chapters on popular music theory and form--Chapter 32 on Popular Music, Jazz, and Blues and Chapter 33 on Recent Popular Music--have been revised and expanded with new examples and recent trends. Examples have been updated throughout the text and workbook to include even more works by historically marginalized composers, giving students exposure to a wider variety of music and helping them better see themselves in the examples.
