Dhol (Bihu Dhol)
Code : P14159

Historical Context: Dates back to the late medieval era, particularly flourishing during the Ahom and Koch dynasties. It was historically patronized in the royal courts (such as Sukaphas court).
Indigenous Evolution: Evolved from ancient tribal log drums into a sophisticated barrel drum specifically designed to accompany the fast-paced Bihu dance.
Geographic Centre: While played across the state, the highest concentration of traditional manufacturers is found in Nagaon, Sivasagar, and Guwahati. 

Double-Faced Asymmetry: Unlike many standard drums, the two faces have distinct functions; the Kobani (right side) provides high-pitched sharp strikes, while the Tali (left side) produces a deep, bass resonance.
Volume-to-Size Ratio: Despite being relatively compact, the Bihu Dhol is famous for its high decibel output, designed to be heard across open festival grounds.
Regional Variants: Apart from the Bihu Dhol, Assam also features the Jay Dhol (used in religious/folk dances) and the Bar Dhol (a larger, more sombre version).

Spiritual Status: Referred to as Deva Vadya (Instrument of the Deities), believed to have been brought to Earth from the heavens by mythical figures like Narada.
The Lifeline of Bihu: It dictates the pace of the Husori (caroling) and the Bihu dance. No Bihu celebration is considered complete without the Dholar Chap (the beat of the dhol).
Symbol of Pride: A Dhol player (Dhuliya) holds a position of high respect in Assamese rural society. 

The Shell (Dima or Khola): Carved from a single block of Jackfruit wood (Kanthal) or Sham wood, chosen for their superior resonance and durability.
Animal Hide:
Tali (Left face): Usually made from thicker Goat skin for a deep bass.
Kobani (Right face): Made from thin, high-tension Parchment or Calf skin for a sharp, high-pitched sound.
Lacing (Barati): Sturdy leather thongs made of cow or buffalo hide used to provide tension between the two heads.
The Band (Maluwa): A bamboo or cane ring that holds the drumheads in place.

Pitch Contrast: The right head is tuned to a significantly higher pitch than the left, creating the signature Tak-Dhum rhythmic contrast.
Tension Adjustment: Tuned by tightening or loosening the Barati (leather straps). In humid weather, players often warm the drumheads near a fire to tighten the skin.
Resonance: The hollowed interior is carefully shaped to ensure the sound reflects perfectly from the wooden walls.

Traditional Covering: Often wrapped in a Gamosa (traditional Assamese cloth) when played, which serves as both decoration and a protective layer.
Lacquer Work: The wooden body is often polished with a reddish-brown or dark natural finish.
Decorative Straps: The shoulder strap (Tikani) is sometimes braided with colourful threads.

Sticks & Hands: Played using a bamboo stick (Dholar Mari) in the right hand for sharp accents and the bare left palm for bass beats.
Posture: Suspended from the neck/shoulder using a strap, allowing the Dhuliya to dance and move vigorously while playing.
Rhythmic Patterns (Chewa): Requires mastery over complex time signatures that accelerate as the dance reaches its climax.

Temperature Control: Drastic changes in humidity can cause the leather to slacken or the wood to crack; it is typically stored in a dry, shaded place.
Skin Conditioning: Occasional application of mustard oil to the leather straps (Barati) keeps them supple and prevents snapping under high tension.
Pest Protection: Since it is made of organic wood and skin, it is often kept in high, well-ventilated lofts to protect it from dampness and wood-boring insects.
