In July 1830, Joseph Smith stated he received a revelation from God for his wife, Emma, to select hymns for the Church of Christ: And it shall be given thee, also, to make a selection of sacred hymns, as it shall be given thee, which is pleasing unto me, to be had in my church.
[1] Initially, it seems that this revelation was interpreted to mean that Emma Smith was commanded to select which hymns were appropriate for use in the worship services of Latter Day Saints and not necessarily to compile a hymnbook.
On September 14, 1835, at a meeting of the high council and the First Presidency at Kirtland, Emma Smith was again counseled to begin compiling a hymnbook in a joint effort with W. W. Phelps: It was further decided that Sister Emma Smith proceed to make a selection of Sacred Hymns, according to the revelation; and that President W.W. Phelps be appointed to revise and arrange them for printing.
[3] Emma Smith selected 90 hymn texts for the hymnal, 35 of which were written by Latter-day Saints.
Many of these texts were revised or corrected by W. W. Phelps to fit with the theology of the early Latter Day Saint church.
An indication of the poverty of the church members in Kirtland at that time is that the hymnal was published in "sexadecimal" form, the least expensive publishing format for books in those days: sixteen pages were printed on both sides of a single sheet, which was then folded, cut, and sewn into the leather binding.
