28 (song)

A song is a musical composition intended or suited for performance by the human voice. Often featuring lyrics, songs typically combine melody, harmony, rhythm, and timbre to create a unified and expressive whole. The performance of a song can be a cappella (voice only), or it can be accompanied by musical instruments.

Songs serve various purposes across cultures and throughout history, including entertainment, storytelling, religious expression, political commentary, and personal expression. They can be simple and folklike, or highly complex and orchestrated.

Key elements of a song include:

• Melody: A sequence of musical notes that forms the primary tune.
• Lyrics: The words of a song, which convey the song's message or tell a story.
• Harmony: The combination of notes that support the melody, creating a richer sound.
• Rhythm: The pattern of beats and accents in a song, which gives it a sense of movement.
• Form: The overall structure of a song, which may include verses, choruses, bridges, and other sections.

Songs exist in a wide variety of genres, including pop, rock, classical, folk, jazz, blues, country, and many others. The term "song" is often used interchangeably with "tune" or "number," although these terms may have slightly different connotations depending on the context.
