Tonic Solfa is a musical notation system that uses assigned syllables to represent the different notes in a musical scale. The system was developed in the 19th century by Sarah Ann Glover and was later popularized by John Curwen in the 1860s. Tonic Solfa is also known as solfeggio, solfa, or solfege, and it is widely used in music education to teach singing and sight-reading. This system simplifies the learning process of music by using a series of memorized sounds that represent specific notes. Other synonyms for Tonic Solfa include movable do, solmization, and Kodály method. These various terms refer to the same basic concept of using a system of syllables to represent musical notes.
