the lower the sound
None. The column of air inside the instrument vibrates. Compare this to a string instrument -- the string vibrates, of course. With the reed instrument, such as a clarinet or bassoon -- the reed vibrates. The vibrating reed causes the column of air inside the instrument to vibrate. However, the brass instruments do not have vibrating parts. What makes the column of air vibrate is the buzzing of the player's lips!
Music, like all sound is made up of sound waves traveling through the air. On a string instrument, the sound wave originates with a wave (actually many waves) on a vibrating string. Wind instruments don't have a string, and the sound you hear doesn't sound much like the vibrating reed of a woodwind or the vibrating lips of a brass players. We hear a wave that is established in the air inside the instrument. Of course, air moves through and out of an instrument, but the wave doesn't leave the instrument. A corresponding sound wave, which we hear, is created outside the instrument, but the wave inside the instrument doesn't leave the instrument any more than the wave on a string leaves the string. We need a term to describe the air that is inside the instrument - the air where the wave is established and that term is "column of air."
The flute is related to the physics of a vibrating column of air. The violin is related to the physics of a vibrating length of string, and the resonance of a sound box. In a drum the membrane vibrates which in turn produces sound. If I walked through an orchestra pit I'm sure I could find other instruments related to physics.
Pitch is determined by the frequency of a sound wave. On a guitar or piano, the wave is established on a string, but in a wind instrument like a trumpet, flute or tuba, the wave is established in the column of air inside the horn. The longer the column of air, the slower the wave will be, and slower waves produce lower pitches. It's just like on a guitar, where the longer portion of a string that's allowed to vibrate, the slower the wave and lower the pitch will be. All that piping in a tuba encloses a very long column of air, so its pitch is low, while the short pipe of a flute produces a high pitch.
Well actually, thereisn't any vibrating. When you blow through the emboucer the air hits the keys. You would look at it like blowing into different bottle where each one is filled with more beans or water

By vibrating, which induces vibration in the air, and sound is vibrations in the air.
You change the pitch by lengthening or shortening the vibrating string, or column of air that is producing the sound. Can be done by fingers against a string (stringed instruments), plucking or hammering shorter or longer strings (piano/harpsichord/harp) opening or covering holes (woodwinds) or changing the length of tubing (brass instruments).

When it is on the guitar, the vibrating string makes the guitar vibrate with it.
No. The bow makes the string vibrate making it produce sound.
A short air column produces a shrill note of higher pitch than a longer air column.

A high-pitched sound results when a string or a column of air vibrates rapidly.
