Music sounds lovely. Playing music sounds lovely. But what's behind the sound? Alfred's Essentials of Music Theory workbook features Books 1, 2, and 3 together in one convenient format, and covers everything from the clefs and note lengths to triads and harmonizing melodies in a minor key. Simple lessons explain the concept, show how it looks written out, and concludes with a few comprehension exercises. Ear-training worksheets are provided, however the music CDs for these lessons are sold-separately. 75 lessons; 125 pages, softcover; spiral-bound. Slightly Imperfect.
