Which pair of instruments is typically found in a basso continuo?

In the context of Baroque music, the basso continuo is a vital part of the ensemble, providing harmonic support and a bass line for the other instruments and voices. The combination of the harpsichord and cello is a classic example of a basso continuo setting. The harpsichord, as a keyboard instrument, is responsible for realizing the chordal harmonies and filling in the harmonic framework, while the cello typically plays the bass line.

This pairing is effective because the harpsichord allows for the intricate and often elaborate chord progressions that characterize the Baroque style, whereas the cello provides a stable and resonant bass foundation. Together, they create a rich texture that supports the melodic lines carried by other instruments or voices in the ensemble.

In contrast, the other options do not fulfill the role of basso continuo as effectively. The piano, while capable of functioning in a similar capacity, is not a traditional instrument associated with the Baroque period. The flute and oboe are woodwind instruments that often play melodic roles rather than providing harmonic support. Lastly, trumpet and trombone are typically used in contrasting roles, often providing brass textures and melodic lines rather than serving in the harmonic framework that a basso continuo requires.
