A melody is a sequence of musical notes that are perceived as a single entity. It is often the most recognizable part of a song, consisting of a series of pitches arranged in a specific rhythm. Melodies can be simple, like a children's song, or complex, like a classical composition. They are typically created using various musical instruments or the human voice. Melodies are essential in many genres of music, including pop, jazz, and classical. They can evoke emotions and tell stories, making them a fundamental element of music. Composers and songwriters carefully craft melodies to engage listeners and create memorable musical experiences.
