I found a very strong stylistic connection between Brahms Third Piano Sonata and his symphonic music when I started to learn the piece. There are some aspects, such as the doubling of the notes, the use of an extense texture or the variety in the articulation, which look for a grandiose sound closer to the sound of the symphonic pieces. A fact which makes me sure about this idea is the impression that Robert Schumann had when he listened first time Brahms Piano Sonatas in Düsseldorf. He said there were “hidden symphonies inside the sonatas” .I had a similar feeling when I started to learn the piece. Being very interested in the orchestration and the imitation of the instruments trough the piano, I decided to do my Research about this topic. My Research Question is: How can we, imaginatively, orchestrate the Brahms Third Piano Sonata trough the piano and how does it affect how we play it?
