Giuseppe Ottavio Pitoni (1657 - 1743) was an Italian composer born at Rieti. He came to Rome as a boy and sang in the choir of SS Apostoli. Foggia gave him instruction in counterpoint, and he became maestro di Cappella, first at Terra di Rotondo and later (1673) at Assisi. In 1676 he went to Rieti, and in 1677 to Rome, where he held various appointments, dying as maestro di Cappella at St Marco, where he was buried.
Pitoni appears to have devoted himself exclusively to church music, and although he did not disdain the modern style with instrumental accompaniment, he is best known for his Masses and other works in the manner of Palestrina.
