John Pyke Hullah was an English composer and teacher of music, whose promotion of vocal training is associated with the singing-class movement. He worked with Charles Dickens and Felix Mendelssohn.

Tonic sol-fa 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 note is given a name according to its relationship with other notes in the key: the usual staff notation is replaced with anglicized solfège syllables or their abbreviations. "Do" is chosen to be the tonic of whatever key is being used. The original solfège sequence started with "Ut", the first syllable of the hymn Ut queant laxis, which later became "Do".
