# bio (long form, separated for readability)
bio: |
  Guido was a Benedictine monk who began teaching around 1013 at Pomposa Abbey, where his antiphonary and staff notation methods earned him the resentment of colleagues who distrusted the new system. He left for Arezzo in 1025, finding patronage under Bishop Tedald and teaching cathedral singers with a speed that startled Italy—large repertoires learned quickly because the notation worked. His treatise Micrologus became the most widely distributed medieval music text after Boethius, and Pope John XIX summoned him to Rome to explain the methods to the clergy. Sickness cut the visit short that summer, and he withdrew to a monastery near Arezzo, likely Camaldolese, where the trail goes cold after 1033.
