Tonic sol-fa

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".

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.

Some of the roots of tonic sol-fa may be found in items such as

When John Windet printed the 1594 edition of the Sternhold and Hopkins Psalter, he added the initials of the six syllables of Guido (U, R, M, F, S, L) underneath the note. Windet explained, "...I have caused a new print of note to be made with letter to be joined to every note: whereby thou mayest know how to call every note by his right name, so that with a very little diligence thou mayest more easilie by the viewing of these letters, come to the knowledge of perfect solfeying..." Rousseau, Curwen and others would have been aware of this popular psalter.

B. C. Unseld and Theodore F. Seward, with Biglow and Main publishers, imported Curwen's tonic sol-fa to the United States, though the method was never widely received. Prior to this, the 9th edition of the Bay Psalm Book (Boston, USA) had appeared with the initials of four-note syllables (fa, sol, la, me) underneath the staff. Reverend John Tufts, in his An Introduction to the Singing of Psalm Tunes in a Plaine & Easy Method, moved the initials of the four-note syllables onto the staff in place of "regular notes", and indicated rhythm by punctuation marks to the right of the letters. These may be considered American forerunners of Curwen's system, though he may not have been aware of them. Tufts' Introduction was popular, going through several editions. Nevertheless, his work probably did more to pave the way for shape notes. When Unseld and Steward introduced tonic sol-fa in the late 1800s, it was considered "something new".
