Henry Madin (7 October 1698 – 3 February 1748) was a French composer at the Chapelle royale and music theorist.
[2] His first music studies took place in Verdun, among the children singing in the cathedral school.
After having directed church choirs at the cathedrals of Meaux, Verdun, Tours, and Rouen), Madin moved to Versailles in 1736, where he was first active for the King's service, relieving the duties of Charles-Hubert Gervais and André Campra.
In 1738, after having ensured membership in the royal chapel, he became "Sous-maître de la Musique de la Chapelle du Roi" – the highest position for a musician at the French court – alongside Esprit Antoine Blanchard.
In 1742 Madin published a treatise on counterpoint, Traité de contrepoint simple, which was inspired by Louis-Joseph Marchand's earlier 1739 publication Traité du contrepoint simple, ou Chant sur le livre.
