On the top platform of Pilatus in Switzerland, there is a grandfather wearing a traditional Swiss costume to blow a very special and special long name. This trombone is a traditional instrument that is circulated in the Swiss Alps. It is shaped like a long-length horn. The so-called "long" means that the horn is 3 to 4 meters long. Later generations improved the traditional trombone and turned the horn into a detachable 3 or 4 knots. After the performance was completed, it was able to be loaded into the pocket when unpacked; and the sergeants shoulder sling appeared as a hunter. Shotgun. My curiosity ran out at this time, and quickly went up to ask the old grandfather for advice~ spurt the gang to blow hard, the strength of the milk is coming out, you guess I finally blew out, no haha ~ This is my first time trying this novel instrument, and my grandfather gave me a thumbs up without hesitation~
