This collection includes over 400+ pieces of sheet music reflecting Hayden Reynolds’s tastes as both a consumer and producer of music. Encompassing a wide array of genres (classical, Tin Pan Alley, blues, jazz, and gospel), as well as Reynolds’s own original compositions, the collection extends chronologically from 1893 to 1963. It subsequently provides a cross-section of developments in the publishing of popular music and innovations in the production and commercialization of said music.
