The E segmentation key structure of the flute The E segmentation key structure (E-mechanism) divides the G and G# keys and adds a linkage structure to the E key. When the E is pressed, the G# key will also close simultaneously, making the pronunciation more stable when playing the treble E.Due to the increase of the E structure and the burden of the key axis, oblique G. is recommendedFlute of inline key structure, flute of winding-line key key structure.The half hole form of E segmentation half hole (E-facilitator) is a metal ring in the sound hole of G# in order to reduce the airflow release of G# bonds, and is the frugal production method to solve the stable tweeter E pronunciation.C# trill key The C# trill key is strange to many players, but it is useful institutions and we should all understand and be familiar with it.The G key straight line flute, if the E structure is attached, the burden of the key axis also increases, when the Pinliness needle-free structure must be increased to relieve the burden of the key axis.But because the Pinliness needle-free structure requires special manual machining, it is also very expensive.In-line flute and E segmentation is generally solved by the above half hole, which is simple and economical and practical.How to play out the notes clearly?—— learned to use the tongue.Each note starts with the tongue, and you must correctly repeat the correct movements of the tongue in the same way, like saying "TA" or French pronunciation "TU".It is to be explained here that the French TU "spit" and Chinese pinyin is by no means a pronunciation, the French TU is equivalent to "special" and "circuitous" combination, Chinese characters cannot replace this pronunciation.If you feel not good, you can read this "special" and "circuitous" quickly, and this sound naturally comes out.Please pay attention to the position of the tongue again!Point: If you can correctly say "TA" or "TU", plays the flute.Repeat the tongue practice and try to keep your lips undisplaced while practicing.
