A real double bass, plucked.
Every note is a recording of a real upright double bass played pizzicato, plucked with the fingers, from the low E string up past the G two and a half octaves higher. Each pluck was measured and tuned to the exact pitch.

A real upright double bass, plucked: warm, woody and round, for jazz walking lines.
