Compared with the former, the pentatonic cross fingering method can play a complete seven-tone scale with the aid of the cross combination of sound holes, usually with the full pressure of 1, the highest note to the high note of 1, and the bass area is completed by leaning and blowing. Playing semitone needs to be achieved by combining fingering with leaning and blowing, and the overall operational performance and convenience are slightly higher than that of the pentatonic open fingering.
At present, Yin Qi Kong Yu's main works are the works of musicians Cao Jianguo and Fang Pudong, and the works of musician Cui Tao.
The seven-tone holes adopt the traditional circular mouthpiece design, which are all set at 1 and arranged into seven tones, with one tone for each hole, which means that the range of the hole is an octave, so it has a relatively unified timbre and intonation. The setting of the alto 4 semitone hole makes the semitone performance of the seven-tone hole very convenient. With breath and prone blowing, a relatively complete 12 average law can be played.
Eight-tone Kong Qiu fingering, teacher Zhang Ronghua adopts the traditional circular mouthpiece design, all of which are based on the bass five tones, one hole and one tone, and seven tones are arranged, with the highest tone being alto 6; All notes are alto 1, and the highest note is treble 2. Because of the combination of semitone hole, fingering and breath control, the average law of 12 can be played more conveniently.
Introduction to Blowing: Fingers naturally bend, fingers press holes. Press the small hole tightly with your fingers to avoid air leakage. It is not advisable to raise your fingers too high or too low when opening a hole. Too high will affect the performance speed, too low will affect the pitch. Generally, you can lift your finger to 2-3 cm above the sound hole of the instrument.
There are 8 holes and 10 holes, and 8 holes are divided into single cavity and double cavity. 10 hole is divided into treble 2 and treble 3. One of the more commonly used fingering (all five fingering), the range is from bass 5 to treble 2 (excluding prone blowing). The second commonly used fingering method (all fingering methods are 1) ranges from alto 1 to treble 5 (excluding prone blowing).
Aerial performance skills
Blowing methods include long sound, air vibration sound, lip vibration sound and so on. Among them, the long note is the basis of Cui's aerial performance skills, which must be full, round, loud, stable and noiseless.
Xun's commonly used skills can be classified into three categories: Qi, Finger and Tongue: including long tone, Qi trill, Finger trill, Lip trill, Slippery, Vomiting, Beating, Empty Beating, Cyclic Ventilation, Cyclic Ventilation and Virtual Blowing. These skills are necessary when playing.
