The pitch of a note IS the frequency the pressure wave oscillates from positive to negative. A guitar string and vocal chords will vibrate faster in a less dense medium.
The frequency of a wave is a fundamental property of the wave and is constant regardless of the medium it's travelling through. Because of this, the frequency remains the same, even though the speed and wavelength of the sound wave may change.
@Blackdragon595 . Tune a string in air to 100 Hz . Play the string in a vacuum, and it will vibrate faster than 100 Hz. Play the string in water, and it will vibrate slower than 100 Hz. Drag is the cause.
@@George.Andrews.OK...so why can sound travel through solids like walls? By your explanation the massively increased drag of a solid should stop it completely.
The important word is "impression". He is there to pretend being a bit daft. It just proves he's a good actor, being very intelligent and knowledgeable. 😊😊

@Blackdragon595 . Lead can be used to soundproof a room. I've seen it used in a hotel wall.
So I guess it'd blow your mind when I tell you sound travels faster in solids?@George.Andrews.
Alan sometimes gives the impression of being a hairs breath away from being a flat earther.

Is that a hare’s breath or a hair’s breadth?
@JohnHirstUK if a hair is breathing it must be the definition of smaller than a quark😁
