Common problems

Squeaking is usually occurs if you are not covering the holes completely or you are blowing way too hard. It is possible to make the flute jump up in pitch (by and octave) by blowing harder while covering all the holes. Sometimes this is desirable but usually not while learning.

Flat notes are caused by blowing too softly. Sharp notes are caused by blowing too hard.

Deteriorated quality of play after a short/long time, maybe fifteen minutes plus. This is usually caused by the flute wetting out. This is caused by the heat front your breath creating moisture as it makes contact with the cooler surfaces withing the SAC chamber and along the bottom of the block. To remove the moisture easily place one finger over the sound hole in front of the block and make a short, sharp blow into the mouthpiece. This will dislodge the moisture and allow you to continue playing for a while. This will only work upto a point. You will then have to stop playing that flute and play another one (one benefit of having more than one flute).
