Dhyangro is a traditional percussion instrument that is commonly used in Nepali folk music. It is a two-headed drum that is played by hand, with one hand striking the larger head (called the "bass head") and the other hand stroking the smaller head (called the "treble head").

The Dhyangro is typically made of wood, with the two heads made of the animal hide (such as goat or buffalo skin) that are stretched over the top and bottom of the drum. The body of the drum is hollow, and it is often decorated with colorful patterns or designs.

In Nepali folk music, the Dhyangro is often played alongside other instruments such as the madal (another type of drum), the sarangi (a stringed instrument), and various wind instruments like the bansuri (flute). It is used to provide a rhythmic backbone for the music, often playing simple patterns or grooves that complement the melody and other instruments.

The Dhyangro is an important part of Nepali culture and is often played during festivals, weddings, and other celebrations. It requires skill and practice to play, and many musicians specialize in playing the Dhyangro as part of a larger ensemble.
