The kuzhal is a traditional double reed wind instrument used in the south Indian state of Kerala.
It is similar in construction to a nagaswaram or a large shehnai, and has a very shrill and penetrating tone.
However, as prelude to melams, it is also used to present solo concert (with a couple of accompanying instruments), in which case it is called Kuzhal Pattu.
The instrument has a wooden body with a conical bore, at the end of which is affixed a brass bell.
The player, who is almost always male, blows through a double reed and closes small holes with both hands.
