Shape notes are a musical notation designed to facilitate congregational and social singing. The notation, introduced in late 18th century England, became a popular teaching device in American singing schools. Shapes were added to the noteheads in written music to help singers find pitches within major and minor scales without the use of more complex information found in key signatures on the staff.

In music, solfège or solfeggio, also called sol-fa, solfa, solfeo, among many names, is a music education method used to teach aural skills, pitch and sight-reading of Western music. Solfège is a form of solmization, though the two terms are sometimes used interchangeably.
