Hamilton: An American Musical is a sung-and-rapped-through biographical musical with music, lyrics, and a book by Lin-Manuel Miranda as well as choreography by Andy Blankenbuehler. Based on the 2004 biography Alexander Hamilton by Ron Chernow, the musical covers the life of American Founding Father Alexander Hamilton and his involvement in the American Revolution and the political history of the early United States. Composed over a seven-year period from 2008 to 2015, the music draws heavily from hip hop, as well as R&B, pop, soul, and traditional-style show tunes. It casts non-white actors as the Founding Fathers of the United States and other historical figures. Miranda described Hamilton as about "America then, as told by America now."
