For music in any 4-shape notation system, where there are 4 different shapes of note-head. Generally this is the system devised by John Connelly in the 1790s, and first used by Little & Smith in The Easy Instructor, c.1801 (having bought the rights from Connelly in 1798).
The right-angle triangle is Fa, round or oval Sol, square or rectangle La, and diamond Mi; the major scale ascending runs Fa Sol La Fa Sol La Mi Fa (often with variant spellings Faw and Law).
The 4-shape system used by Andrew Law does not position the notes on a staff, and reverses two of the shapes, so that the rectangle is Faw and the triangle Law. This system did not become as popular, and is found only in Andrew Law's own publications, for instance The Art of Singing.
A third type of 4-shape notation was used by Charles Woodward in his Ecclesiæ Harmonia, but this, too, did not become popular.
The Norristown Musical Teacher was designed as a bridge between 4-shape and 7-shape notation, and includes options for several sets of alternative syllables, and note-head shapes that follow easily on from the 4-shape system (in fact they are readable as 4-shape notation). However, there is no known further usage of this intermediate system.
This list is not complete, and will continue to grow as works are added to IMSLP. The list also includes some books that were published in a or in standard 'round' notation as well as 4-shape, even if the 4-shape version has not yet been uploaded.
N.B. The 4 syllables (derived from the Guidonian Gamut) were commonly used in British music instruction between the 17th - 19th centuries. For an early example, see Playford's Introduction to the Skill of Musick. It was only in the nineteenth century that the British 4-syllable system was termed the Lancashire Sol-Fa (see Greenwood's Lancashire Sol-Fa) to distinguish it from the newly introduced Tonic Sol-Fa.
