Analysing Ludwig van Beethoven's Op.102 Sonatas for piano and cello in terms of form and performance techniques

Ludwig van Beethoven is one of the leading composers of both Classical Western Music and the Classical Period. With almost all of the works he has written, he has brought his own innovations. Sonata form is one of them. In the works he wrote in sonata form, Beethoven made some unusual changes rather than the classical order of the period. The works he wrote in sonata form are symphonies, chamber music works, sonatas for solo instrument, works written for orchestra. In his piano and cello sonatas, which are also the subject of this research, L. V. Beethoven went beyond the classical order and made a unique signature. As we will see in this study, he took the classical structure of "exposition, development, reintroduction" in a different way. In this study, I will try to explain and present to my colleagues as a cellist what awaits the performers in terms of virtuosity in these sonatas for piano and cello, how Beethoven handles these sonatas, how we can handle them as a form, and how Beethoven uses the sonata form with his musical style.
