The polyphonic style was brought to Spain by the previous generation of composers led by Penalosa, and the mystical intensity of Ibérian music reached its maximum influence in the following generation with Victoria's tenure at Rome.

Morales occupies the intermediate historical position between these two, along with the contemporary keyboard music of Antonio de Cabezon; his music shows some influence of earlier polyphony as well as looking forward to functional harmony.

Morales' fame is also increased by the fact that his polyphony was performed in Mexico during the early days of the Spanish domination there. Todd McComb
