Programed instruction can be applied fruitfully in teaching about music within and outside Western culture. The content of such study could include cognitive material, such as the social role of music in various cultures, the history of music, the visual identification of instruments, and perhaps notational skills; performance skills, dealing with unfamiliar metric organizations, scale resources, or notational schemes; and development of aural perceptional ability. Preparation of software materials first requires specifying objectives, writing the program, and testing its effectiveness. Experts must be encouraged to prepare these materials and teachers must be encouraged to use them. Although we cannot expect programed instruction to accomplish more than the instructional objectives we list, it can supplement the teacher in four important ways: as an outside source of information, as a diagnostic tool, as a remedial aid, and as further stimulation for the precocious student. Through programed instruction, our students will no longer be limited to understanding music of their own culture. Instead, they will be polymusical. (JK)
