ornament table

Haydn did not leave a systematic ornament table, but his ornamentation follows broadly the C.P.E. Bach tradition: trills begin on the upper auxiliary, appoggiaturas are given significant rhythmic weight, and mordents are short and sharp.

In Haydn's slow movements, the written ornaments are structural, not decorative — especially appoggiaturas, which carry harmonic dissonance and must resolve with expressive weight. In fast movements, ornaments should be crisp and rhythmically precise. When adding unwritten ornaments on repeats (acceptable and expected), add them sparingly and in the style of the movement, not in the Romantic sense.
