Would you like to play some indie pop? What about our piano sheet music for Say Something, the best-selling single by American indie pop duo A Great Big World in collaboration with Christina Aguilera? What a great ballad to start learning on the piano! Begin with our easy piano music Level 1 and if you are having trouble with reading the notes, try our music sheets with the note names instead of symbols. Christina Aguilera contacted A Great Big World after exposure of Say Something on the American reality TV show So You Think You Can Dance? and subsequently released her own cover version in November 2013.
