Marc'Antonio Ingegneri (also spelled Ingegnieri, Ingignieri, Ingignero, Inzegneri) (c. 1535 or 1536 – 1 July 1592) was an Italian composer of the late Renaissance.
Even though he spent most of his life working in northern Italy, because of his stylistic similarity to Palestrina he is often considered to be a member of the Roman School of polyphonic church music.
Not much is known about his early life, but he probably had family from Venice, and he likely studied with Cipriano de Rore at Parma, and Vincenzo Ruffo at Verona.
Ingegneri was close friends with Bishop Nicolò Sfondrato, later Pope Gregory XIV, who was intimately involved with the reforms of the Counter-Reformation and the Council of Trent, and this influence is present in his music, which usually shows the simplification and clarity of the Palestrina style.
His madrigals tend to be conservative, frankly ignoring the innovations of composers such as Luzzaschi and Marenzio who were experimenting with vivid chromaticism and word-painting around the same time.
