What is the most common mode of Mongolian folk music?

Mongolian folk music can be described as rich and colorful, which is closely related to Mongolian people's nomadic life in the northern grassland of China since ancient times. In modern times, many nomadic tribes gradually settled down and engaged in semi-agricultural and semi-pastoral labor, and also formed a musical and cultural system in which grassland culture and agricultural literature coexisted. China's music system is adopted by Mongolians, with pentatonic scale as the main part and few tone sandhi. If it appears, it mostly constitutes a comprehensive seven-tone scale mode. Feather mode is the most common mode in Mongolian folk music. The instruments commonly used in folk instrumental music are flute, Ma Touqin, Sanxian and Hu Si. Instrumental music mostly comes from folk songs, such as pastoral songs and long-tune folk songs, and is often played with flutes. Their rhythm is slow and free, and their music style gives people an open, long and unrestrained feeling. Herdsmen can't live without horses, and the works reflecting the life of herding horses in Mongolian music and dance are also very common, which makes people feel the galloping horses and the brave character of Mongolians. The flute often uses the sound of spitting when expressing this passionate emotion. Xu Lian's "Three Spits" effect can simulate the sound of horseshoes, and there is also a special air finger technique to simulate the neighing of horses. When playing adagio lyric tunes or loose boards and intros, the flute often uses an eraser to imitate the effect of Ji Ma Touqin, and the fingers must fluctuate smoothly. Generally, the slow speed begins to accelerate gradually, and the fingers turn into vibrato.
