Musical collaborations occur when two or more artists work together to create a song or album. These partnerships can bring together different styles, genres, and influences, resulting in unique and innovative music. Collaborations can happen between singers, songwriters, producers, or even entire bands, allowing for a blend of talents and ideas. Such collaborations can be seen in various forms, from duets between vocalists to feature appearances on tracks. Notable examples include Beyoncé and Jay-Z, who have teamed up on multiple projects, and Elton John collaborating with Lady Gaga. These partnerships often expand an artist's reach and introduce them to new audiences.
