Legato is a musical term that describes a smooth and connected style of playing or singing. In legato, notes are played or sung in a way that minimizes any gaps or breaks between them, creating a flowing sound. This technique is often indicated in sheet music by a curved line connecting the notes, signaling the performer to maintain a seamless transition. Musicians use legato to convey emotion and expressiveness in their performances. It is commonly found in various genres, including classical music, where composers like Ludwig van Beethoven and Wolfgang Amadeus Mozart employed legato to enhance the lyrical quality of their melodies.
