Mexican composer. Sumaya was born in Mexico City where he was a Priest Musician at the cathedral and eventually became maestro de capilla in 1714. He was highly rated in his day and is considered by many to be one of the great composers of New Spain. His move to Oaxaca in the last years of his life is still largely unexplained. It may have been precipitated by a conflict with the Cathedral Chapter. He seems to have been very happy with the set-up in the beautiful city of Oaxaca and wrote some of his finest music there. He had a choir of twenty singers and ten players. He also worked closely with Indian musicians.
