According to dictionary definitions, the notion of collaboration is neither simple nor clear. An online American Heritage Dictionary defines collaboration as "to work together, especially in a joint intellectual endeavor; to cooperate, as with an enemy of occupying one's country." The purpose of this article is to propose a theory of school/college collaboration in music education that is based on the principle of tensegrity, or tensional integrity. Although this theory is not intended to be one that can be fully generalized, there are specific elements of the theory that may prove helpful to those involved in collaborative endeavors in a variety of settings. This theory represents the conceptual workings of the Eastman-Rochester Partnership (now known as the William Warfield Partnership), a school/college collaboration involving the Eastman School of Music and the Rochester, New York, City School District. The elements of the theory were developed through (a) a review of the research literature on educational collaborations in music education and in general education, (b) the author's analysis and interpretation of the data collected throughout the course of the fieldwork, (c) other interpretations of the data provided by peer reviewers, (d) interpretations of the data from other partnership participants, and (e) an examination of other partnership models currently in place across the country. Consideration and incorporation of the information received from these various perspectives provide a form of triangulation, helping to ensure a more valid interpretation of the data.
