The GPC Air Bag allows the wind musician to practice inhalation and exhalation. To use the Air Bag, practice emptying and filling the lungs by slowly rebreathing air several times in a row. An air bag can also be used as a rough gauge of a person's vital capacity on their instrument. After a full inhalation, exhale into the bag filling it as much as possible. Hold the air in the bag with a finger over the tube. After positioning the instrument for playing inhale from the bag and start playing the instrument. The bag then displays a visual quantity of air. This model is a 5-liter capacity rubber air bag. NOTE: Due to the manufacturing process, the bag will have a greasy/slippery residue upon shipment which will need to be washed off before use.
