According to statistics data in 2009, the Hmông people in Vietnam had a population of over one million people, making them one of the larger ethnic minorities in northern Vietnam. The Hmông reside mostly in the provinces of Hà Giang and Lào Cai. They have diverse folk music and folksongs. The khèn (or also known as kềnh) is an aerophonic instrument made up of six bamboo tubes of different lengths. These tubes are put through a wooden resonator. The upper part of resonator is small, connecting to another bamboo section that forms a blowing pipe. A small bronze reed is attached at the part put through the wooden resonator on each horizontal bamboo tube. The shortest and the longest bamboo tubes have two parallel reeds, producing unison sound. Pressing holes are outside the resonator. The player covers the pressing hole of the section and then blows air into it to make the reed vibrate and produce sound. Each tube creates a different sound depending on the length and size. The Hmông playing and pressing techniques include clapping, tremolo, and staccato as well as simultaneity, chord, and harmony. Kềnh of the Hmông people is a polyphony instrument with a bit cracked sound. The register of Kềnh is about an octave. The Hmông people blow the Kềnh during entertainment activities, at funerals, or on the way to the market. Traditionally, the instrument is only for men to accompany singing.

In the folksongs of Tày-Nùng in Cao Bằng, Hà lều (also called as Lượn Phủ) of the Nùng Inh people are the most attractive melodies. Hà lều is often sung during fun activities, but most commonly on the occasion of January and February—the season of festive singing—the season of lồng tồng. Hà lều is sung in pairs by alternating two men and two women. When one side stops, the other side responds immediately. If both sides respond well without interruption, the song will be very smooth. With Hà lều, we can hear that one sings with a low voice, and the other sings with a high voice, and one waits for the other person for a harmony. This is a unique feature in comparison with many other folk songs. The lyrics of Hà lều usually use a style of a seven-seven word meter poem; the fifth syllable of the second sentence must rhyme with the last syllable of the first sentence. This type of rhyme finding is a typical characteristic of Hà lều.
