Shape note singing is a unique musical tradition that uses a system of shapes to represent different musical notes. Each note is assigned a specific shape—triangle, circle, square, or diamond—making it easier for singers to read music, especially those who may not be familiar with standard notation. This method helps participants quickly learn and sing hymns or folk songs in a group setting. Originating in the early 19th century in the United States, shape note singing is often associated with Sacred Harp music. It emphasizes community participation and is typically performed in a square formation, encouraging a sense of unity among singers. This tradition continues to thrive today, with gatherings held across the country.
