An example of figured bass: only the bass part (left hand) with the figures would be written. The chords in the right hand show how it might be played. The figures give the intervals from the bass note up. If no figure is given the chord is a 5 3 chord (an ordinary triad)

Basso continuo is a form of musical accompaniment used in the Baroque period. It means "continuous bass".

Basso continuo, sometimes just called "continuo", was played by an instrument providing chordal accompaniment such as a keyboard instrument or plucked string instrument such as the lute along with another bass instrument such as cello, violone, or bassoon. The keyboard instrument was normally a harpsichord but could also be an organ, such as a small portative instrument.
