This course begins a more focused investigation of the materials and expressive possibilities of Western music from the common practice era (circa 1700-1900). There are also forays into jazz theory, theories of world musics, and freer styles of composition. Topics include modes, the use of seventh chords, nonharmonic tones, tonicizations, modulation, and musical form. Work on sight singing and dictation continues. Students also learn to play scales, harmonic progressions, and to harmonize melodies at the keyboard.
