Duke Ellington famously promoted the Hammond Piper Autochord organ upon its release around 1970–1971. Designed for hobbyists, the portable Piper featured "automatic chording" and unique synth-like sounds. Ellington was featured in promotional materials for this "rare" instrument, which aimed to make playing accessible to non-musicians.

Key Details of the Hammond Piper & Ellington Promotion

• Promotion: Duke Ellington appeared in advertisements for the Hammond Piper around 1973.
• The Instrument: Released in 1970–1971, the Hammond Piper was a single-manual (61 keys) auto-chord organ aimed at beginners. It was marketed as a "pop music" instrument.
• Sound Features: It featured several solo sound keys, including trombone, accordion, flute, violin, trumpet, and "dynamute" (a wah-wah sound).
• Marketing: Hammond marketed the instrument with a group called "The Piperettes" to showcase its ease of use in shopping malls and home shows.
• Legacy: Despite its high-profile promotion, the Piper was not a professional-grade organ and used early transistor technology, making it hard to repair today.
