The Boy Who Heard Music is a rock opus that began life as an Internet novella written by musician and songwriter Pete Townshend. Townshend wrote in the foreword to the novella that he typically sketches out his opera in this way to lay out the plots and storylines, but in this case he published the material on an Internet blog site in 2005 and 2006, opening an interactive discussion with readers. The work was later released as a maxi-single and album by The Who and adapted as a rock opera.
