Chamber music was an essential part of Istomin’s career for more than thirty years. After 1980, the last year of activity for the Trio which he had founded with Isaac Stern and Leonard Rose, he performed chamber music only on very special occasions.

His repertoire includes some sixty works and, unlike solo piano and concerto, is almost entirely devoted to Beethoven and Brahms.

Istomin played all the Beethoven chamber music with piano (with the exception of the three early piano quartets and the music for flute), a total of thirty-one works. In 1970, the Beethoven bicentenary year, he performed the complete cycle with Stern and Rose, in four series of eight concerts. Istomin also performed nearly all of Brahms’ chamber music in various contexts, with the exception of the Piano Quartet Opus 60 and the Horn Trio Opus 40.

In addition, there are of course the great trios by Schubert and Mendelssohn, as well as a single trio by Haydn (Hob.XV:10) and another by Mozart (K. 502) – but there is no Russian music (aside from the Andante of the Rachmaninoff Cello Sonata!) and very little French music (with the exception of Franck’s Violin Sonata and Ravel’s Trio).

What is also striking is the relatively small number of musicians with whom Istomin agreed to play chamber music, apart from Casals (with whom he gave many concerts and also privately played the complete cello repertoire of sonatas and concertos) and his partners in the Trio. Here is the list of his partners, classified by instrument and in chronological order of collaboration. Occasional partners are written in italics, regular in normal characters.

Violonists : Alexander Schneider, Joseph Fuchs, Szymon Goldberg, Yehudi Menuhin, Henryk Szeryng, Irina Botchkova, Jaime Laredo, Leonidas Kavakos, Pinchas Zukerman.

Violists : Milton Katims, Milton Thomas, Michael Tree, Pinchas Zukerman, Bruno Giuranna, Youri Bashmet, Choong- Jin Chang.

Cellists : Mischa Schneider, Frank Miller, Paul Tortelier, Sharon Robinson, Mstislav Rostropovich.

String Quartets : Kroll, Budapest, Guarneri.

Clarinetists : David Oppenheim, Robert Marcellus.

Singers : Jenny Tourel, Maureen Forrester, David Lloyd, Eileen Farrell, Adele Addison, Donald Gramm.

Here is the list, as complete and precise as possible, of the chamber music works (including lieder) that Istomin performed during his career, with mention of the periods during which he played them and of the recordings which were made.
