The Trio for Violin, Horn and Piano by György Ligeti was completed in 1982.

Ligeti had composed little since he completed his opera, Le Grand Macabre, in 1977, having only finished a few smaller pieces, like Hungarian Rock (chaconne) and Passacaglia ungherese for harpsichord.

[2] Influenced by sources as diverse as sub-Saharan African drumming, the music of Conlon Nancarrow, and the piano music of Chopin and Schumann,[2] the Trio is considered to be the watershed moment that opened up his "third way," a style that Ligeti claimed to be neither modern nor postmodern.

Ligeti recalled his reaction to the suggestion: "[a]s soon as he pronounced the word 'horn' somewhere inside my head I heard the sound of a horn as if coming from a distant forest in a fairy tale, just as in a poem by Eichendorff.

The composition explores the use of major and minor harmonies as free sonorities without following established patterns of common practice tonality.
