Double-pipe Bau is based on the traditional Bau, through the combination of two Bau, on the basis of not destroying the natural and most beautiful sound of Bau, to expand the range and performance of Bau.
For many improved Hulusi and Bau, in order to expand the sound range, the quality of the main sound of Bau before the expansion is usually reduced. The Bau does not make any changes to the traditional Bau tonic, but only expands the vocal range through combination, thus ensuring the quality of the original Bau tonic.
As mentioned earlier, the fingering of the Bau is based on the difference in the tuning of the drum, and the two main heads are combined to achieve the purpose of expanding the range. Therefore, the traditional Bau's fingering is used when playing, and the combination can be done. It is not like adding a key Bau. fingering. As long as you get used to the fingering combination and switch between the two heads reasonably, it is easy to play the double-pipe Bau.
The bass 6 to treble 3 is the most beautiful when the traditional Bawu tone is 5. The tone of the other sounds is slightly worse, and the treble volume is also weak. The double-pipe Bau combines two supervisors, which can be switched and replaced between the two supervisors, avoiding the two weak tones of the traditional Bau—treble 5 and 6. best performance.
