<P> Ultimately, it is difficult to categorize the band using a single genre only, since they bridge so many . This has been attributed partly to the fact that both Joseph and Dun are self - taught musicians, meaning that while producing their work they broke many musical conventions that they were not aware of, including staying confined to a single genre . </P> <P> Instrumentally, Twenty One Pilots bring a mix of piano (sometimes an electronic keyboard or a keytar), synthesizers, drums (sometimes mixed with electronic drums), vocals, and occasionally the ukulele and bass . Lyrically, their songs are written by Joseph, who incorporates both sung and rapped lyrics . Music journalist Carl Wilson has noted that Joseph's rapping is often compared to that of Macklemore, yet he wrote "but among the ranks of post-Eminem white rappers, I find Joseph more probing, sardonic, and expressive ." Joseph has stated that he never intended to become a rapper, but that when attempting to fit poetry which he had written with music, he found that rapping elements of it was the only way for it to fit within the song . </P> <P> Joseph came up with the band's name while studying All My Sons by Arthur Miller, a play about a man whose choice to send out faulty airplane parts for the good of his business and family caused the death of twenty one pilots during World War II . Joseph explains that the story's themes of moral dilemma and choosing between the easy and the right decision inspired the name and formation of the band . "Bicycle Thief" and "Chill Coat" were among some of the rejected band names . </P> <P> The band's name was originally stylized as "twenty one pilots" on their earlier cover art; however, by the time of their second album Regional at Best, the formatting was changed to "twenty øne piløts" with slashes through the O's . </P>
