The Mandolin Family refers to a group of stringed instruments that share a similar shape and playing technique. This family includes instruments like the mandolin, mandola, mandocello, and mandobass. They typically have a rounded back, a flat front, and a fretted neck, and are played with a plectrum. These instruments are known for their bright, resonant sound and are commonly used in various music genres, including bluegrass, folk, and classical music. The mandolin family is characterized by its use of double courses, meaning each string is paired with another, enhancing the instrument's tonal richness.
