The Big Broadcast, Vol.8, Jazz and Popular Music of the 1920s and 1930s

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.

Vintage swing refers to the original, dance‑era swing recorded mainly during the 1930s and 1940s in the United States. It is characterized by a buoyant “swing” rhythmic feel (uneven, lilting eighths), strong four‑to‑the‑bar pulse, walking bass lines, and riff‑driven horn writing. Typical ensembles were big bands with sections of saxophones, trombones, trumpets, and a rhythm section of guitar (four‑to‑the‑bar), piano, double bass, and drums (hi‑hat on 2 and 4). The style balances tightly arranged call‑and‑response figures with spotlighted improvised solos. Vocals often draw on the blues, with scat singing and witty songcraft common. The “vintage” designation points to the sound of the period: monaural 78‑rpm recordings, ribbon mics, room‑forward balances, and lively ballrooms—music designed for social dance styles like the Lindy Hop and jitterbug.
