A one-man band or one-woman band is a musician who plays a number of instruments simultaneously using their hands, feet, limbs, and various mechanical and/or electronic contraptions. One person band musicians also often sing while they perform. The simplest type of "one-person band" — a singer accompanying him/herself on acoustic guitar and playing a harmonica mounted in a metal "harp rack" below the mouth — is often used by buskers and folk music singer-guitarists. More complicated setups may include wind instruments strapped around the neck, a large bass drum mounted on the musician's back with a beater which is connected to a foot pedal, cymbals strapped between the knees or triggered by a pedal mechanism, tambourines and maracas tied to the limbs, and a stringed instrument strapped over the shoulders (e.g., a banjo, ukulele or guitar). Since the development of Musical Instrument Digital Interface (MIDI) in the 1980s, musicians have also incorporated chest-mounted MIDI drum pads, foot-mounted electronic drum triggers, and electronic pedal keyboards into their set-ups. In the 2000s and 2010s, the availability of affordable digital looping pedals enables singer-musicians to record a riff or chord progression and then solo and/or sing over it.
The earliest known records of multiple musical instruments being played at the same time date from the 13th century, and were the pipe and tabor. The pipe was a simple three-holed flute that could be played with one hand; the tabor is more commonly known today as a snare drum. This type of playing can still be heard in parts of rural France, in England and Spain. An Elizabethan-era woodcut shows a clown playing the pipe and tabor. An 1820s watercolour painting shows a one-man band with a rhythm-making stick, panpipes around his neck and a bass drum and tambourine beside him. Henry Mayhew's history of London street life in the 1840s and 1850s described a blind street performer who played bells, the violin and accordions.
