Pythagoras's cousin Octavius wants to win the music contest, but his pipes are out of tune. Pythagoras compares the faulty pipes to his own perfect set. Together the cousins find a relationship between the longest and shortest of Pythagoras's pipes, which gives them an idea for how to fix Octavius's set. The answer's not so easy when cousins Reyna and Amara ask Pythagoras to fix their lyres so that they can join in the contest, too. Will Pythagoras tune in to the solution in time?
