Lumen ad revelationem (dated 1610) shows him to have been at least a competent contrapuntist. Gomes moved to Évora Cathedral, where he rose to the position of treasurer. On the title-page of a manuscript volume of chants edited by him, he is described as having been at Vila Viçosa, where the chants had been sung. A Libera me and several villancicos also survive in Évora, though it is uncertain whether these are by him or by another João Gomes listed as second organist at Évora Cathedral in 1651. A six-part motet ascribed to João Gomes, Subvenite sancti Dei (now lost), was in the library of João IV.
