An annotated measure by measure comparison of the two Boccanegras reveals techniques in Verdi's orchestration which remained consistent throughout his career, and serves as a guide to examine variance and growth in the evolution of his craft. The letters quoted document the history of both Boccanegras, air his opinion about musical instruments, and express his desire for modifications to nineteenth century Italian orchestras-- modifications in seating, balance, and the adoption of a standard pitch to avoid persistent problems between banda and orchestra.
As a result of the comparison of the two Boccanegras documentation is provided showing that Verdi deleted over half of the original pages of Boccanegra I when composing the revision. This and other added features make this dissertation valuable to scholars doing research in the orchestration of Verdi, nineteenth century opera orchestration or the study of both Boccanegras.
