fortepiano idiom
English composer
Definition
Haydn's later sonatas were written for the English fortepiano rather than the harpsichord — an instrument with a lighter, more transparent tone than the modern concert grand, capable of subtle dynamics but lacking the modern piano's sustain.
Interpretive Guidance
On a modern piano, the fortepiano idiom suggests a lighter touch, shorter note values, and more careful attention to articulation than in Romantic repertoire. The bass should not overwhelm the treble; Haydn's textures are transparent. Avoid the sustain pedal except for specific effects — Haydn's harmony moves quickly and benefits from clean harmonic changes.
