Hans Erich Pfitzner (5 May 1869 – 22 May 1949) was a German composer, conductor and polemicist who was a self-described anti-modernist. His best known work is the post-Romantic opera Palestrina (1917), very loosely based on the life of the sixteenth-century composer Giovanni Pierluigi da Palestrina and his Missa Papae Marcelli.

In music, a serenade (; also sometimes called a serenata, from the Italian) is a musical composition or performance delivered in honour of someone or something. Serenades are typically calm, light pieces of music. The term comes from the Italian word serenata, which itself derives from the Latin serenus. Sense influenced by Italian sera "evening", from Latin sera, fem. of serus "late".
