Although the current, exhaustive studies of Brahms' works have covered many aspects of the composer's art, it is still surprising that his large-scale, five-movement Piano Sonata No.3 has in many ways been insufficiently studied by scholars who have emphasized the genre of the piano sonata and the aspect of performance practice over the work's more diverse features. Another reason that this early work has been understudied could in fact be that his later compositions in other genres, such as his symphonies, chamber music or choral music, have been perceived by scholars to represent best his most mature, comprehensive style. This dissertation will therefore examine the orchestral underpinnings of this monumental work which owes most often its already mature artistic essence to Brahms' multi-instrumental approach.

Samuil Feinberg was an important performing pianist, composer, and one of the protagonists of Russian Piano School. Among his numerous piano compositions, the Sixth Sonata is one of the most complex and illustrative of his deeply personal musical ideas. The following performer's guide offers some ideas on interpreting and performing the sonata from the perspective of Russian school pianism. Having trained in Russia for nearly a decade with two of Feinberg's most eminent disciples and assistants (Tatiana Galitskaya and Liudmila Roschina) makes this author part of living chain back to his pedagogical principles. I will draw upon my knowledge and expertise to illustrate how interpretation of Feinberg's Sonata No. 6 embodies many of the particular and subtle aspects of the Russian piano school technique.
