The difference between the eighth five-year plan and the double-tube eighth five-year plan

The most remarkable difference between Bawu and the double-tube Bawu is that the traditional Bawu is made of bamboo tubes, with a narrow range, which is only suitable for playing five-tone national music. Double-barreled Bawu is a new type of wind instrument, which is improved in recent years. It is composed of two Bawu with different lengths and different tones by tying strings, which greatly broadens the range of Bawu. The traditional Bawu can only play alto 6, and the improved double-tube Bawu has three more notes than the traditional Bawu, namely alto 7, treble 1 and 2. The commonly used double-tube 85 has the following two key combinations, namely, the combination of F key 85 and bB key Xiaobao, and the combination of G key 85 and C key Xiaobao. When playing a tune in F or G, Dabawu plays with the fingering of 5, and Xiaobao plays with the fingering of 1. Playing music with the double-tube Bawu can master Bawu's various fingering skills skillfully, and also increase Bawu's artistic expression. At present, 80% of the music can be played with the double-pipe bawu.

The difference between Bawu and Hulusi is the same as that between Bawu and Hulusi. The cucurbit silk plays vertically and horizontally. Gourd silk takes the gourd as the sound barrel, which plays the role of * * * when playing, while the double-tube eight-five is played with the mouth wrapped and the mouth as the * * * cavity, and its principle is the same as that of gourd silk. I hope to take my advice, thank you.
