Pablo Nassarre (or Nasarre;[1] 1650–1730) was a Spanish priest, organist, and Baroque composer. His work, Escuela Música según la práctica moderna, made him an important theorist of the Baroque era.
Nassarre was born blind in Alagón, Zaragoza, in 1650. He moved to Daroca to be taught by Pablo Bruna, also a blind composer. At age 22, Nassarre became a Franciscan and joined the Royal Convent of San Francisco in Zaragoza, where he was the organist until his death.
He also opened a school of harmony and counterpoint, where José de Torres and Joaquín Martínez de la Roca were his students.
