Donald Duck in Math Magic Land - Music

Mathematics? That's for eggheads. Eggheads? Now, hold on, Donald, - You like music, don't you? - Yes. Well, without eggheads, there would be no music, Come on, Let's go to ancient Greece, to the time of Pythagoras, the master egghead of them all, Pythagoras? The father of mathematics and music, Mathematics and music? You'll find mathematics in the darndest places, Watch, First we'll need a string, Stretch it good and tight, Pluck it, Now divide in half, Pluck again, You see? It's the same tone, one octave higher, Now divide the next section, And the next, Pythagoras discovered the octave had a ratio of 2:1, With simple fractions, he got this, And from this harmony in numbers developed the musical scale of today, By golly! You do find mathematics in the darndest places. You can imagine how excited Pythagoras was when he shared his findings with his pals, a fraternity of eggheads known as the Pythagoreans, They used to meet in secret to discuss their mathematical discoveries, Only members were allowed to attend, They had a secret emblem, The pentagram, Let's see what the topic is for today, What's going on? lt's a jam session. Give me something with a beat! So from these eggheads, the Pythagoreans, with their mathematical formula, came the basis of our music of today,
