Toka (bamboo Clapper)
Code : P14156

Agrarian Roots: Emerged from the rural farming communities of Assam. It was originally used by farmers in the fields to scare away birds and wild animals before being adapted into a musical instrument.
Eco-Friendly Design: Reflects the deep-rooted Bamboo Culture of Assam, where almost every household item and musical tool is crafted from locally available bamboo species.
Evolution: Over centuries, it moved from a functional field tool to a refined musical instrument used in both Husori (village carolling) and stage Bihu. 

Simplistic Brilliance: It is one of the worlds most basic percussion instruments, consisting of a single piece of bamboo split down the middle.
The Sound of Bihu: The Clack-Clack sound is the definitive signal that a Bihu performance is about to begin. It sets the Tala (rhythm) for the singers.
Variations: It comes in three main sizes: the small hand-held Toka, the medium-sized Paati Toka, and the large Bor Toka (which is placed on the ground). 

Feminine Energy: While played by all, the smaller Toka is a signature instrument for female Bihu dancers (Bihuwatis), who use it to maintain rhythm while dancing.
Ritualistic Use: It is an inseparable part of Rongali Bihu. In some tribal traditions, the sound of the Toka is believed to awaken the earth for the spring planting season.
Manufacturing Hubs: Found in every village across Assam, but the finest musical-grade Tokas are crafted by artisans in Barpeta and Majuli. 

Base Material: Exclusively made from Bijuli Bamboo or Jati Bamboo. These species are preferred because they are flexible, strong, and do not crack easily under repeated impact.
Selection: A mature bamboo pole (usually 2–3 years old) is selected. It must have at least two nodes (joints).
The Split: The bamboo is split longitudinally from one end, stopping just before the final node, which acts as a natural hinge.
Hand-Grip: The unsplit node serves as the handle, while the two split halves strike against each other to produce sound. 

Fixed Pitch: The Toka does not have a variable pitch. Its sound depends on the thickness and length of the bamboo used.
Resonance: A wider bamboo produces a deeper, hollower thud, while a thinner, narrower bamboo produces a sharp, high-pitched crack.
Precision Cutting: The length of the split determines the springiness and the speed at which the instrument can be played. 

Surface Treatment: The outer green skin is often scraped off and polished to a smooth, pale yellow or light brown finish.
Etching: Many performers etch traditional motifs, like the Pepa or Japi designs, onto the bamboo surface.
Natural Lustre: Occasionally rubbed with a small amount of mustard oil to give it a slight sheen and prevent the bamboo from drying out. 

Action: Played by holding the base node in one hand and shaking or striking the split ends against the other palm, or simply squeezing the two halves together.
Lightweight: Its extreme portability allows dancers to carry it easily while performing complex footwork.
Speed: Requires wrist flexibility to produce the rapid, staccato beats required for fast-paced Bihu melodies. 

Cracking Prevention: Bamboo can crack in extreme heat or very dry weather. Keeping the instrument in a moderately humid environment is key.
Smoke Curing: Traditional players often hang their Tokas above the kitchen fire (Chulha) for a few days. The smoke cures the bamboo, making it resistant to pests and fungal growth.
Node Integrity: The hinge (the node where the split ends) is the most vulnerable part. Players ensure it is never over-extended to prevent the bamboo from splitting completely.
