To play the instrument, the player (called a bagpiper or a piper) will inflate the bag and will place it under his left arm when the bag is fully inflated. The piper will now keep the pressure in the instrument with his arm. When he has to stop breathing in the bag, he’ll use his elbow to press the bag and keep the pressure on. This way of playing gives the opportunity to the player to play music during a long period of time without stopping for the need of breathing. Once the instrument is inflated, the piper have to tune one of the drones to match the chanter and, after that, he'll tune drones to match them together. If the piper do this operation carefully, he will be able to have a perfectly balance instrument. Once it's done, the player can start playing his instrument.
