Figured bass notation is a musical shorthand that provides performers with the information needed to realize a harmony from a given bass note, typically using numbers and symbols to indicate intervals above the bass. This method allows composers and arrangers to specify chords and their inversions without writing out every note, facilitating easier improvisation and accompaniment. Understanding figured bass is crucial for recognizing various harmonic functions, including cadential resolutions, tonicization techniques, and the use of embellishing tones.
