An instrument air compressor controls the application of air for operating valves in pneumatic instruments.

The barometer is the instrument that is used to measure the air pressure.

The latest weather forecasting instrument invented was the barometer. This instrument measures air pressure.
Plant air refers to compressed air used for general plant operations and equipment, while instrument air is a specific type of compressed air of higher quality used to operate pneumatic instrumentation and control devices that require clean and dry air. Instrument air typically has lower moisture content and fewer contaminants than plant air to prevent issues with sensitive instruments.

To play a musical instrument by blowing air through it with your mouth, you need to position your lips correctly on the mouthpiece or reed of the instrument. Then, blow air steadily and adjust the pressure to produce different notes. By controlling your breath and finger movements, you can create music on the instrument.
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."
