Tuotilo (died 27 April 915) was a Frankish monk at the Abbey of Saint Gall. He was a composer, and according to Ekkehard IV a century later, also a poet, musician, painter and sculptor.[1] Various trope melodies can be assigned to Tuotilo, but works of other mediums are attributed with less certainty. He was a student of Iso of St. Gallen and friends with the fellow monk Notker the Stammerer.[1]
