“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 2 great loves – math & 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’s won 20+ awards for educational STEM songs and song videos in national contests (NSF, ASANational Museum of MathematicsCAUSEQL-SIGMAA, STEM Art and Film Festival) 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 or the 2024 NMMATYC meeting) 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 or the 2024 El Paso Science Festival).  A dozen of his STEM songs have even been played on TV or radio!

His songs yielded meaningful learning gains in an NSF-funded randomized experiment and helped land an award-winning follow-up NSF grant to write and assess interactive statistics songs (see our JSE paper), which led to his co-founding the VOICES STEM song conference (featured in Forbes).

Lesser’s math-and-music work has been featured in print media (e.g., Australia’s largest paper), institutional media (e.g., newsletter or newscast), STEM songwriter media, podcasts, 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 a regional PBS-TV children’s show to a newspaper syndicated feature The Mini Page (with 20 million readers in 500+ papers!).

Lesser has published 100+ STEM lyrics and pioneering papers (e.g., in J. of Statistics Education, Mathematics TeacherTeaching StatisticsEJSMEJ. of Mathematics Education (or here), VOICES, eCOTS, Primus, and one of the most-viewed papers in the history of J. of Mathematics and the Arts) on using music in math/statistics class, as part of broader work on educational fun.  His songwriter cred is not limited to STEM: he’s also had awards, airplay, album cuts, etc. for his non-STEM songs, including being a Winner and 4-time Finalist in the New Mexico Music Awards!
