India has a rich musical tradition, and while leather is not commonly used in the construction of the primary classical musical instruments, it is employed in some musical accessories and folk instruments. Here are a few examples:

Tabla Covers: Tabla is one of the most popular percussion instruments in Indian classical music. While the main body of the tabla is made of wood and metal, leather covers, known as puris or tabla heads, are essential components. These leather covers are used to create the distinctive sounds of the tabla.
Dholak and Mridangam Heads: The dholak and mridangam are two other percussion instruments commonly used in India. They have leather drumheads on both ends that are struck with the hands or sticks to produce sound.
Leather Straps for Sitar and Tanpura: In some cases, leather straps or strings are used to secure frets or maintain tension on stringed instruments like the sitar and tanpura. These straps help in fine-tuning the instrument.
Leather Accessories: Leather is used in the making of various musical accessories such as straps for holding the harmonium or other instruments, carrying bags, and cases to protect instruments during transport.
Folk Instruments: In some folk and traditional music contexts, leather may be used in instruments like the dhol (a large double-headed drum) and various tribal drums. These drums often have leather drumheads that produce specific sounds.

It’s important to note that in the context of Indian classical music, instruments like the sitar, flute, sarod, and veena do not typically use leather in their construction. These instruments primarily consist of wood and metal or brass components.

In summary, while leather is not a primary material in the construction of most classical Indian musical instruments, it is used in some accessories and folk instruments, especially for drum heads and straps. Leather is valued for its acoustic properties and durability in these applications.
