Jug

A jug is is a container for liquid, with a handle and an opening for pouring or drinking from.

As a musical instrument, the jug provides a rhythmic bass accompaniment. Jugs produce sound when air is blown over the top opening. Different size jugs produce deeper or higher musical tones with a smaller jug having a higher pitch than a large one. Most players use only one jug at a time, thus, play only one note.

The jug band was at the height of popularity in the 1920s, when such bands as Cannon's Jug Stompers were popular. Typically jug bands play folk music, either hillbilly or blues, but the 13th Floor Elevators, a psychedelic band from Texas, featured an "electric jug" in the 1960s.
