The primary objectives of the project were to develop non-book instructional materials for use in Music Education, to put these materials into use, and to subsequently evaluate and refine the materials. The audiovisual materials and the equipment needed to present them included an overhead projector and various types of transparencies. The use of varied media in music education showed advantages over traditional modes of presentation in teaching and learning efficiency, meaningful reinforcement, and creative use of color for added motivation and interest. The media approach offers variety and caters to individual differences in learners. A list of specific situations in which transparencies can be used (i.e., to illustrate the concept of enharmonic tones) follows a description of the advantages of using an overhead projector. Although project members encountered difficulty in the reproduction of high quality sound, use of available sound equipment proved to be adequate. The techniques employed and the equipment needed are described in detail. Funding for the project was provided under Title IV of the Elementary-Secondary Education Act of 1965. This is a layman's version of ED 029 500. A glossary is appended. (RP)
