Figured BassIt was developed in the early Baroque period and it was a system of musical shorthand that made the writing of keyboard parts easier.
It was customary for the composer to write out the bass line & to place Arabic numerals above or below the figured bass to indicate the harmonies.
In figured bass the Arabic numerals represent the intervals that sound above a given bass part. Certain abbreviations have become well known.
