Instruction: These three sounds are mostly made with the nasal pathway. For M, press the lips together and make a sound blowing air out of the nose. For N, press the tongue on top of the upper portion of the mouth and blow air out of the nose. And for NG, press the very rear portion of the tongue and upper mouth together and blow air out of the nose.
These three sounds are made the same way using the air you breath out of the nose. The only difference is the lip and mouth position. If you plug your nose and try to make this sound, it will not be correct.
