Angel making music.

Bartolomeo Caporali was a Perugian painter and illuminator whose career in the 1460s–90s makes him an important figure in the formation of the Umbrian school that would produce Perugino and ultimately Raphael. His Angel Making Music belongs to the type of altarpiece spandrel or predella panel depicting heavenly musicians that Umbrian workshops produced prolifically for the numerous ecclesiastical commissions flowing from Perugia's churches and confraternities. Such angels were simultaneously decorative and theologically functional, representing the perpetual celestial liturgy mirrored in earthly worship.

Caporali paints the angel in the Umbrian tradition's characteristic pale, soft palette — the rosy flesh, pale gold hair, and pastel robe tones that would become the signature look of Perugino's angels. The musical instrument is rendered with careful accuracy, the fingers positioned on the strings or keys with the documentary interest of a painter who had studied actual performance.
