The objectives of the Manhattanville Music Curriculum Program (MMCP) were to develop a music curriculum and related materials for a sequential learning program for students from the primary through high school years, and also prepare effective means for the training of teachers to use this curriculum. Over 80 musicians and educators throughout the country participated in the developmental work. The major product of this operation was the "Synthesis", a comprehensive curriculum for grades 3 through 12. In addition, MMCP conducted a separate but related study for the development of an early childhood curriculum, "Interaction" and three feasibility studies: The Electronic Keyboard Lab, The Science-Music Program, and the Instrumental Program. In the development and study of plans for teacher re-education 23 workshops for music educators were sponsored by colleges and universities. The resulting project has presented alternatives to the status quo of music education while the products of this project have made available to the profession another choice in educational operations in music.
