ground bass
English composer
Definition
A compositional technique in which a short bass line repeats continuously while the upper part develops varied figurations above it. Purcell was a supreme master of the ground bass, composing some of his most expressive and inventive music in this form for keyboard and for voice.
Interpretive Guidance
In keyboard grounds, vary the touch, dynamics, and articulation of the upper part across each repetition to sustain interest over the repeating bass. The bass should remain steady and slightly subordinate to allow the upper part to sing.
