Norwich sol-fa system

Tonic sol-fa (or tonic sol-fah) is a pedagogical technique for teaching sight-singing, invented by Sarah Ann Glover (1785–1867) of Norwich, England and popularised by John Curwen who adapted it from a number of earlier musical systems. It uses a system of musical notation based on movable do solfège, whereby every tone is given a name according to its relationship with other tones in the key: the usual staff notation is replaced with anglicized solfège syllables (e.g. do, re, mi, fa, sol, la, ti, do) or their abbreviations (d, r, m, f, s, l, t, d). "Do" is chosen to be the tonic of whatever key is being used (thus the terminology moveable Do). The original solfège sequence started with "Ut" which later became "Do".

Glover developed her method in Norwich from 1812 resulting in the "Norwich Sol-fa Ladder" which she used to teach children to sing. She published her work in the Manual of the Norwich Sol-fa System (1845) and Tetrachordal System (1850)

Curwen was commissioned by a conference of Sunday school teachers in 1841 to find and promote a way of teaching music for Sunday school singing. He took elements of the Norwich Sol-fa and other techniques later adding hand signals. It was intended that his method could teach singing initially from the Sol-fa and then a transition to staff notation.

Curwen brought out his Grammar of Vocal Music in 1843, and in 1853 started the Tonic Sol-Fa Association. The Standard Course of Lessons on the Tonic Sol-fa Method of Teaching to Sing was published in 1858.

In 1872, Curwen changed his former course of using the Sol-fa system as an aid to sight reading, when that edition of his Standard Course of Lessons excluded the staff and relied solely on Tonic Sol-fa.

In 1879 the Tonic Sol-Fa College was opened. Curwen also began publishing, and brought out a periodical called the Tonic Sol-fa Reporter and Magazine of Vocal Music for the People, and in his later life was occupied in directing the spreading organisation of his system. The Sol-fa system was widely adopted for use in education, as an easily teachable method in the reading of music at sight, but its more ambitious aims for providing a superior method of musical notation have not been generally adopted.

By the end of the nineteenth century, this notation was very widespread in Britain, and it became standard practice to sell sheet music (for popular songs) with the tonic sol-fa notation included.
