In music, a serenade 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".

Music is the arrangement of sound to create some combination of form, harmony, melody, rhythm, or otherwise expressive content. However, definitions of music vary depending on culture, though it is an aspect of all human societies and a cultural universal. While scholars agree that music is defined by a few specific elements, there is no consensus on their precise definitions. The creation of music is commonly divided into musical composition, musical improvisation, and musical performance, though the topic itself extends into academic disciplines, criticism, philosophy, psychology, and therapeutic contexts. Music may be performed using a vast range of instruments, including the human voice to sing, and thus is often credited for its extreme versatility and opportunity for creativity.
