Annotation: Pythagoras and his cousin Octavius want to win a music contest but first they must figure out how to play their musical instruments in unison, something that's never been done before. Pythagoras makes an important discovery-notes that sound pleasant together have a certain mathematical ratio. When Pythagoras applies this ration to his cousin's pipes and lyres, the result is music to his ears.

Publisher Description:
Julie Ellis and Phyllis Hornung Peacock team up once again to explore Pythagorean ratios in this humorous sequel to WHAT'S YOUR ANGLE, PYTHAGORAS?

Pythagoras and his cousins want to win a music contest, but first they must figure out how to play their instruments in tune, something that's never been done before.
While trying to fix the problem, Pythagoras makes an important discovery--notes that sound pleasant together have a certain mathematical relationship. When Pythagoras applies this ratio to his cousins' pipes and lyres, the result is music to the ears.
