Juan Bermudo OFM (c. 1510 in Écija, Province of Seville – c. 1565) was a Spanish Friar Minor who is best known as a composer, music theorist and mathematician.
[1] Bermudo entered the Franciscan Order in 1525, belonging to the Province of Andalusia.
A subsequent long period of illness led Bermudo to retire from his service as a preacher.
[2] Bermudo's first published work resulting from his studies was his Libro primero de la Declaración de instrumentos (1549), dedicated to King John III of Portugal.
