Figured bass, or thoroughbass, is a kind of musical notation in which numerals and symbols (often accidentals) indicate intervals, chords, and non-chord tones that a musician playing piano, harpsichord, organ, lute (or other instruments capable of playing chords) play in relation to the bass note that these numbers and symbols appear above or below.
A string is the vibrating element that produces sound in string instruments such as the guitar, harp, piano (piano wire), and members of the violin family.
