terraced dynamics
A Baroque-era approach to dynamics where volume changes occur in sudden, discrete steps rather than gradual crescendos and diminuendos.
In Depth
Terraced dynamics (also called stepped dynamics) are characteristic of Baroque music, where dynamic changes tend to be immediate rather than gradual. A passage is played at one consistent dynamic level, then shifts abruptly to another — like stepping between terraces rather than climbing a slope. This approach was partly dictated by the harpsichord, which cannot change volume through touch, and by Baroque performance conventions that emphasized structural contrast over emotional gradation. The [concerto grosso](/term/concerto%20grosso) epitomizes terraced dynamics through its alternation between the full orchestra (forte) and the small concertino group (piano). Vivaldi and Handel frequently exploited this contrast for dramatic effect. The development of the fortepiano in the late 18th century, which could produce gradual dynamic changes, enabled the crescendo and diminuendo that became central to Classical and Romantic expression. The Mannheim orchestra's famous "Mannheim crescendo" was revolutionary precisely because it replaced terraced dynamics with gradual swells — audiences reportedly rose from their seats in excitement.
The Mannheim orchestra's gradual crescendo was so revolutionary in the 1750s — after decades of terraced Baroque dynamics — that audiences reportedly stood up from their seats in astonishment at the novel effect.
