The Piano Trio in C minor, Op. 101, by Johannes Brahms is scored for piano, violin and cello, and was written in the summer of 1883 while Brahms was on vacation in Hofstetten, Switzerland. It was premiered on 20 December of that year by Brahms, violinist Jenő Hubay, and cellist David Popper.
The trio is in four movements:
C minor, sonata form
C minor, ternary form. This movement takes the form of an intermezzo, in place of the traditional scherzo and trio.
C major, ternary form. This movement involves the use of alternating time signatures - 3/4 and 2/4, as well as 9/8 and 6/8.
C minor, sonata form. Ends in C major.
