Piano Quartet no. 1

Piano Quartet No. 1 in G minor, Op. 25 is a chamber work by Johannes Brahms, composed in 1861. The piece embodies Romantic-era harmonic richness and dramatic contrasts between vigorous, rhythmic passages and expansive lyrical writing across its four-movement structure, and it represents an important early achievement in Brahms's chamber music that helped establish his approach to large-scale instrumental forms.
