Learn to play flute with this interactive breathing app. With each exhalation you play each note from the scale and the app shows you the appropriate fingering positions. It trains users to make steady exhalations so they will be able to play steady notes.
Breathing apps are based on a breathing technique called Pursed Lip Breathing and they are designed to train kids to make exhalations longer. This is especially recommended for people with breathing related (asthma, emphysema, COPD) and stress related (anxiety, blood pressure) disorders. In general, medical doctors encourage people to perform Pursed Lip Breathing in order to get more oxygen, to gain more energy or to relax.
