What are the foundations for the oboe practice  Primary oboe to pay attention to four oboe exercises; they are: mouth type use, open flat chin, open throat, abdominal muscle support, these points will be very good to learn the oboe.Control of mouth type in oboe practice is important and we can do such an experiment to check whether our mouth type is correct.Do long tone exercises in the easier pronounced midone C1.Whether the whistle can be moved left and right in the playing, and the tone will not be affected.This experiment tells us that the truth of the mouth is loose, it can make the instrument vibrate so that the sound is full, relaxed and round.Assuming a candle less than a foot ahead of the practitioner, force (do not drum the cheek) to blow a very fine airflow to blow it, so that a roughly correct mouth shape is formed.The oboe is different from the oboe with whistles.The former has no mouth that can be used as a resonant cavity, so it must be used to resonate from the whistle in other methods, so it is very important to open the chin to form a resonance cavity in the mouth (this experience is like a big saliva in the mouth).After playing, the breath comes out of the throat, not directly into the whistle, but to the upper soft palate, to the nose, or even to the forehead.
