These are musical instruments where the music is produced by blowing air through the holes on the instrument. The flow of air is controlled by the finger movements of the player. Holes are made on bamboo, wood and metal and air is allowed to pass through them smoothly. The air that emanates is controlled with the fingers to produce melodious music. And some of the major wood/wind instruments of Kerala are Sanku, Kuramkuzhal, Kombu, Nagaswaram and Odakkuzhal.
