This is especially true for younger students, whose lung capacities aren't on par with adults yet. The flute itself also does require a lot of air to produce sound, because only half the air you blow goes inside. The rest goes to waste. This is why breathing techniques are among the first things that students learn when studying the flute. Aside from these techniques, there are also tools such as the breathing bag and breath builder which will improve one's lung capacity over time. So don't fret if you feel like you can't blow enough air into the flute at first. It takes time! Why not jump to our flute technique page to find out more ways to improve.
