Tunebooks
In 1835, Walker published a tunebook entitled The Southern Harmony, using the four-shape shape note system of notation. This collection was revised in 1840, 1847 and 1854. In 1846 he issued The Southern and Western Pocket Harmonist. Intended as an appendix to the Southern Harmony, the Pocket Harmonist contains a large number of camp-meeting songs with refrains. In 1867 (preface signed October 1866), Walker published a tunebook entitled Christian Harmony, in which he adopted a seven shape notation. He incorporated over half of the contents of The Southern Harmony in the Christian Harmony, and he added alto parts to those pieces which had lacked them before. For the additional three shapes, Walker devised his own system - an inverted key-stone for "do", a quarter-moon for "re", and an isosceles triangle for "si" (or "ti"). Walker issued an expanded edition of Christian Harmony in 1873. In the same year, he brought out a collection of Sunday school songs entitled Fruits and Flowers.
