Tablature (or tabulature, or tab for short) is a form of musical notation indicating instrument fingering rather than musical pitches. Tablature is common for fretted stringed instruments such as the lute, vihuela, or guitar, as well as many free reed aerophones such as the harmonica. Tablature was common during the Renaissance and Baroque eras, and is commonly used today in notating rock, pop, folk, ragtime, bluegrass, and blues music.
