High and low

Before naming anything you need to hear one thing: whether the sound goes up or down. That is pitch, and it depends on frequency — how many times per second the air vibrates. Faster means higher. The ear does not compare frequencies as numbers but as ratios: if one note vibrates twice as fast as another, we hear them as “the same but higher”, and we call that an octave. That is why the scale repeats every eight notes and not every ten or twelve.
