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.
