The Club of Song, or COPA, is an international organization that promotes the use of music as a tool for social change. It was founded in 2002 by a group of musicians, activists, and educators who wanted to use music to bring people together and create positive change in their communities. The organization works to support local music initiatives, provide resources for musicians, and promote the use of music as a tool for social justice. COPA also works to raise awareness about the importance of music in society and its potential to bring people together.
