Aerophones: Air-based instruments
The whistleblowers
Any instrument with a vibrating column of air is an aerophone. Humans have been using this method for ages to create very loud tones and send them as warning signals over long distances.
Pitch depends on the length of the pipe. The human voice is also an aerophone.
