THIS WORK PROVIDES NEW INSIGHT INTO THE INNER WORKINGS OF BACH'S PARTITAS AND SUITES, ESTABLISHING VARIOUS WAYS IN WHICH THE COMPOSER LINKED SEVERAL MOVEMENTS OF A SUITE TO PRODUCE A UNIFIED EFFECT. Musicians -- listeners, performers, and scholars alike -- have often felt a profound connectedness between various movements in multimovement works by the great composers. But sensing musical unity is one thing; showing it is another. In _Aspects of Unity in J. S. Bach's Partitas and Suites_, David Beach examines many of the forty-four works by Bach in this genre-for keyboard, orchestra, and solo instruments, including the beloved solo works forviolin and for cello-from this perspective. Through careful attention to motivic and harmonic repetitions at various structural levels, made plain to the eye in numerous annotated musical examples and diagrams, Beach establishes that Bach often did link several movements of a suite in various ways, sometimes by overt but often by more subtle means. _Aspects of Unity in J. S. Bach's Partitas and Suites_ thus provides new insight into the inner workings of these great works. David W. Beach is a renowned music analyst and historian of music theory who recently retired as Dean of the Faculty of Music, University of Toronto. He co-translated Kirnberger's _The Art of Musical Strict Composition_ and edited _Aspects of Schenkerian Theory_ [both for Yale University Press] and is co-editor of _Music Theory in Concept and Practice_ [Eastman Studies in Music, University of Rochester Press].
