The guitar solos originated from Barnard's brief tenure in Genesis. Hackett modified sections that Phillips and Barnard had written while adding his own arrangements to the song. He realised that neither member had made a sound that resembled an actual musical box, so he took the opportunity to record a guitar lick that is heard before the lyric "Here it comes again". Gabriel, a big fan of The Who at the time, pushed for Rutherford to come up with a "ballsy, attacking" section in a similar style to their guitarist Pete Townshend. Gabriel incorporated themes of violence and sex into the lyrics. Collins was inspired to play a rolling drum part during the middle section from hearing "The Weaver's Answer" by Family, and put it to the rhythm. "All of a sudden", speaking about "The Musical Box" at this point, "It's 'wahey we're off!'".
