Sonata", which has influenced all forms of instrumental music from the Baroque Period to the present, means a multi-part piece composed for one or two instruments. It can be said that from the time of the first sonatas to the current times, almost all composers who are known to have written pieces of instrumental music have produced works in the form of duo sonata.Harboring the musical characteristics of the Classical and Romantic periods, both sonatas written for the cello and piano by Johannes Brahms hold an important place among the works of chamber music. Additionally, upon examination of the cello parts of the sonatas in terms of performance techniques, it can be seen that both sonatas are among the most difficult pieces for performers.This study aimed to examine the right-hand techniques in the cello parts of the two sonatas written for the cello and piano by Johannes Brahms, who was one of the prominent composers of the Romantic Period.
