Sämtliche Klaviertrios – Vol. I (1755–1760) is a collection of piano trios by Austrian composer Joseph Haydn, comprising works composed between 1755 and 1760. These pieces display the early Classical (galant) style with a keyboard-led texture supported by violin and cello lines, and they represent an early stage in Haydn's development of the piano trio as a distinct chamber-music genre.
