Trainor, Fallon and _Tonight Show_ house band the Roots performed the track on classroom instruments: a xylophone, a triangle, tambourines and even some plastic hand-clapper things. (Hi, Questlove. We see you.) We were already pretty into the song, which celebrates big butts and positive body image, but man, adding a kazoo makes it so much better. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3273928/jimmy-fallon-meghan-trainor-the-roots-perform-all-about-that-bass/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3273928/jimmy-fallon-meghan-trainor-the-roots-perform-all-about-that-bass/"},"headline":"Jimmy Fallon, Meghan Trainor and the Roots Perform \"All About That Bass\" On Classroom Instruments","datePublished":"2014-09-05T16:14:31.000Z","dateModified":"2026-04-13T07:13:00.263Z","description":"Entirely on classroom instruments","url":"https://time.com/3273928/jimmy-fallon-meghan-trainor-the-roots-perform-all-about-that-bass/","keywords":["Newsfeed","Television","Music","jimmy fallon","The Roots","meghan trainor"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt0f8c25e493a9662a/6986a228adae444379544d16/screen-shot-2014-09-05-at-11-14-55-am.png?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Samantha Grossman","jobTitle":null,"url":"https://time.com/author/samantha-grossman/"}],"articleSection":"","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt0f8c25e493a9662a/6986a228adae444379544d16/screen-shot-2014-09-05-at-11-14-55-am.png?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Screen Shot 2014-09-05 at 11.14.55 AM","caption":"","creditText":"","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/tag/time-section-newsfeed/","name":"Newsfeed"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/3273928/jimmy-fallon-meghan-trainor-the-roots-perform-all-about-that-bass/","name":"Jimmy Fallon, Meghan Trainor and the Roots Perform \"All About That Bass\" On Classroom Instruments"}}]}] ```
