“Find, find the value of pi — starts 3 point 1 4 1 5 9.
A good ol’ fraction you may hope to define, but the decimal never dies ….”

— from Larry Lesser’s American Pi”, winner of the National Museum of Mathematics’ Pi Day of the Century song contest

ABOUT THE MATHEMUSICIAN:  To support his mission to motivate learning, Professor Lesser integrates two great loves – math and music!  As the Mathemusician (some say “the Weird Al Yankovic of math ed”), Lesser incorporates song and guitar in interactive classes and keynotes, facilitating explorations and performing songs spanning content such as infinity, pi, and worldly contexts such as the lottery!

Lesser has won a score of awards for educational STEM songs and song videos in recent national contests (NSF, ASANational Museum of MathematicsCAUSEQL-SIGMAA) and has given presentation-performances for national audiences ranging from mathematics teachers (e.g., an SRO audience of 800+ to open the 2009 NCTM conference in Nashville) to mathematicians (e.g., 2008 MAA MathFest banquet or the 2014 Bridges meeting) to statisticians (e.g., 2013 USCOTS banquet) to general audiences (e.g., 2015 MoMath event and 2018 NSF video showcase). Some of his STEM songs have even been played on TV (6 songs) or radio (5 songs).

His songs yielded meaningful learning gains in an NSF-funded randomized experiment and helped land an award-winning followup NSF grant to write and assess interactive statistics songs (see our JSE paper), which launched a spinoff STEM song network/conference, VOICES, which was featured in Forbes.  Lesser’s work has been featured in print media (e.g., Australia’s largest paper), institutional media (e.g., college newsletter or the closing story of university newscast), STEM songwriter media, and mass media (from El Paso to Jamaica!). While he focuses on secondary and postsecondary levels, Lesser has also produced math-and-music material for younger audiences, ranging from an appearing on a regional PBS-TV children’s show to writing an issue of the syndicated feature The Mini Page read by 20 million people in 500+ newspapers).

Lesser has published about 100 math/stat lyrics (and 70 STEM poems) and pioneering papers (e.g., in J. of Statistics Education, Mathematics TeacherTeaching StatisticsEJSMEJ. of Mathematics EducationJ. of Mathematics and the Arts, VOICES,  and eCOTS) on using music in math/statistics class, as part of broader  work on educational fun.  He’s also had success (awards, airplay, album cuts) for his non-STEM songs, including being a Finalist for Best Album in the 2021 New Mexico Music Awards.
