First corrected by TheSamuelWells A few people have noted that the "clarinet" is actually a "soprano saxophone". I am very sorry to all the music nerds. Let me know if you spot anything else! Filming and editing by Alex Genn-Bash Written and performed by Matt Parker and Ayliean MacDonald Blocky animations by Willow Marler Produced by Nicole Jacobus Music by Howard Carter Design by Simon Wright and Adam Robinson All soprano saxophone music was recorded live on location.
