The Hesperian Harp is a shape note tunebook published in 1848 by Dr William Hauser. Subtitled A Collection of Psalm and Hymn Tunes, Odes and Anthems, it is named after Hauser's plantation, Hesperia, in Jefferson County, Georgia. The word "harp" is often found in the titles of such tunebooks, most famously the Sacred Harp. The Hesperian Harp was probably the largest shape note tune book of its day, containing 552 pages of music, including 36 songs composed by Hauser. It uses the four-note system of notation pioneered by William Little and William Smith.
