The flute is the most basic instrument in the woodwind family. It is a reedless wind instrument, otherwise known as an aerophone, which creates sound from the flow of air from an opening. Flutes are often made of wood in Europe while silver is the main flute construction material in the United States.
The acoustic guitar is hollow-bodied and uses only acoustic techniques to produce sound which means it does not have electric amplification. Its name is a retronym of the electric guitar to differentiate them from each other. Its strings could be made of steel or nylon while its top plate could be made of cedar or spruce. At the top is a circular hole with a diameter of 3.25 inches to 3.5 inches which strengthens and reinforces the produced sound.
The bagpipe is an aerophone, a musical instrument class, and uses enclosed reeds to vibrate by movement of stored air in a bag. It is more commonly referred by pipers as “pipes”. You might be familiar with the Irish uilleann pipes or the Scottish great highland bagpipe but there are also varieties of bagpipes coming from regions all around the Persian Gulf, Northern Africa, and Europe.
