What is continuo part?

The continuo part, often referred to as "basso continuo," is a foundational element in Baroque music, providing harmonic support and structure. Typically played by instruments like the harpsichord, organ, or lute, it consists of a bass line with accompanying chords. Musicians performing the continuo part are expected to improvise harmonies based on figured bass notation, allowing for both flexibility and creativity within the ensemble. This practice was essential for establishing the harmonic framework of the music during the Baroque period.
