Short Character Pieces for String Quartet and an Analysis of Motivic Development and Evolution of Form in Johann Sebastian Bach's Keyboard Concerto nach Italienischem Gusto, BWV 971 (1735) and Mozart's Piano Sonata, K. 333 (1783)

Abstract

Throughout history there has been much discussion on the evolution of musical forms and structures. There has also been discussion of motivic development as a means of unifying one or more musical compositions. This thesis analyzes motivic development in the first movement of J. S. Bach's Concerto nach Italianischem Gusto, BWV 971, and the evolution of form as reflected in the third movement of Mozart's piano sonata in B-flat major, K. 333. It is the goal of this thesis to establish that the ritornello form of Bach's Concerto nach Italianischem Gusto relates to the formal design of Mozart's sonata, not only in the division of sections, but through the use of motivic development as well.
