This booklet identifies major competencies for each course offered in the secondary music education program in the Philadelphia school system. Music is seen to be a mode of expression in responding to and interpreting life and nature. It promotes the development of aesthetic judgment. The booklet outlines up to eight competencies for each of nine elective music courses and three instrumental courses offered in grades seven through 12. The music courses include basic music, music literature, music theory, harmony, solfege, and sight singing. For each competency, numerous behavioral objectives are listed by which mastery can be evaluated. For example, a competency in harmony is that students will demonstrate a knowledge of secondary triads and their inversions. A behavioral objective for this is to construct and label triads in root position and inversions. Other competencies include demonstrating an understanding of meter signature (music theory); knowing periods in music history and their representative composers (music literature); and showing refined tone control and quality (advanced instrumental).
