diatonic harmonica
A small free-reed instrument with ten holes, each producing two different notes (one on blow, one on draw), designed to play in a single key with bending techniques for chromatic notes.
In Depth
Little Walter revolutionized blues harmonica by cupping a small microphone against the instrument and playing through a guitar amplifier — the distorted, overdriven sound he created influenced rock guitarists and remains the benchmark for amplified blues harp.
