John Eagleton's Sacred Harmony is described on the title page as 'A Set of Tunes, adapted to Dr Watts's Psalms & Hymns, the Revd G. Burder's Supplement and the Revd J. Wesley's Collection: Composed in an easy Style, and the whole figured for the Organ, Piano Forte, &c.'.
The collection was published in London, being 'Printed for the Author, and sold by JAMES PECK, No 47 Lombard Street. Sold also by BUTTON & WHITAKER St Pauls Church Yard. T. WILLIAMS, Stationer's Court. and by all MUSIC SELLERS in the kingdom.'
The collection consists of 27 hymn tunes, all with texts: it written in four parts, with the air on the third stave down, bracketed together with the bass. While it is not dated, Lightwood dates it to 1816.
