Beautiful Classical Smaller Pieces, duo,trio,etc

A number of critics and many classical music aficionados consider Schubert's String Quintet, Op. 163, D. 956, also known as his Cello Quintet, to be the greatest piece of chamber music ever written. It's certainly among the greatest IMO.

Also, if a solo piano work is considered to be within the category that is being asked about, I would suggest Chopin's Piano Sonata No. 3, Op. 58.

Ptss,
Great thread Idea. Many worthwhile suggestions are/will come out of this.

With my own ears I heard the great pianist,Arthur Rubenstein, say the Schubert Op 163 Quintet is the greatest piece ever written and that he wanted it played at his funeral.

My own personal favorite piece, period, is the Brahms Op 78 Violin Sonata in G major.
My favorite recording of same is the Josef Suk/Julius Katchen ,Decca 466 393-2 .

The Brahms Clarinet Quintet should be added to the list.

Schubert's Cello Quintet of course.

Of the top of my head;
Brahms Sextet No. 2 in G Major, Op. 36 (Sextet for Strings)
Beethoven's String Trios
