# Resonance and formants

Every object and every hollow space has frequencies at which it vibrates most easily. These are its resonances. When a sound contains those frequencies, the object picks them up and makes them stronger. Your mouth and throat form a space like this, and their resonances are called formants. When you change from ee to ah, your vocal folds keep the same pitch, but your tongue and lips move the formants, and that is what changes the vowel. The wooden body of a violin and the gourds under the keys of a balafon do the same job for their instruments.
