Jazz harp is a subgenre and instrumental practice that brings the concert harp (and, increasingly, amplified and electric harps) into jazz idioms—swing, bebop, cool, Latin, post‑bop, and contemporary jazz. Pioneers demonstrated that the harp can comp, solo, and drive rhythm sections much like a piano or guitar while exploiting uniquely idiomatic textures: glissandi, harmonics, pedal bends, and lush rolled voicings.
Its sound world blends jazz harmony and improvisation with techniques native to the harp—selective damping, resonant pedal shifts, and percussive effects—producing timbres that can be crystalline and airy or surprisingly punchy and groove‑forward. Modern players range from straight‑ahead and Latin approaches to boundary‑pushing fusion and chamber‑jazz settings, often using amplification and effects to expand the instrument’s palette.

The modern concept of jazz harp crystallized in the United States during the 1950s, when harpists began applying bebop and cool‑jazz language to the concert harp. Early innovators proved the instrument could comp, walk bass lines, and improvise with the agility expected of jazz rhythm‑section instruments, while using glissandi, harmonics, and pedal colors as expressive signatures.
Through the 1970s and 1980s, jazz harp diversified in ensemble settings—from small combos to larger chamber‑jazz and third‑stream configurations. Players integrated Latin and Afro‑Cuban grooves, Brazilian bossa and samba feels, and modal/post‑bop harmony. Amplification became common, enabling clearer articulation and more assertive roles in bands, while some artists experimented with electric/electroacoustic harps.
A new generation of harpists has established the instrument across mainstream jazz venues and festivals worldwide. They balance tradition (swing, standards, hard‑bop vocabulary) with global rhythms, modern harmony (melodic‑minor modes, extended tertian and quartal voicings), and contemporary production aesthetics. Today, jazz harp thrives in small‑group contexts (trios and quartets), voice‑and‑harp formats, and cross‑genre collaborations that intersect with world fusion, chamber jazz, and ambient‑leaning substyles.
