Listeners often appreciate how the tabla does not merely act as a percussive element but rather interacts dynamically with the music, enhancing the overall performance. Yet, what makes the tabla’s ability to carry melody so extraordinary is that it defies the conventions of physics that govern percussion instruments.

For many years, traditional views held that circular drums lacked the capability to create distinct musical notes associated with melodies. Despite these beliefs, Indian artisans managed to craft these ‘singing’ drums well before any scientific exploration could explain the phenomenon.

Acoustic Properties of Drums

Most drums are, in strict acoustic terms, considered to be flawed in their ability to produce harmonious music. When a drumhead is struck, the skin vibrates in a chaotic manner, resulting in multiple overlapping vibrations called modes. Each mode produces sound at distinct frequencies, which can lead to dissonance rather than harmony.

This complexity is less of an issue for string instruments, where tones align in an orderly sequence known as the harmonic series. In these instruments, harmonic overtones complement the primary note, creating a rich, melodic sound. However, the sound produced by circular drumheads, like those of the tabla, does not conform neatly to such structures, making it ostensibly unsuitable for melodic purposes.

Traditionally, physicists believed that percussion instruments could only serve to maintain rhythm and could not carry melodies due to their inherent acoustic limitations. The case of tabla, however, challenges this understanding, signifying that something unique was at play within the tradition of Indian drumming.

C.V. Raman’s Groundbreaking Research

In 1919, C.V. Raman, a notable physicist based in Calcutta, set out to explore the acoustic properties of Indian drums. Attending concerts, he observed that the tabla and mridangam produced pitched sounds, with their higher notes blending harmoniously with string instruments. This observation led him to embark on a systematic study of their acoustics.

On January 15, 1920, Raman’s findings were published in the journal Nature in a paper entitled “Musical Drums with Harmonic Overtones.” Raman concluded that Indian drums, contrary to established belief, could produce overtones that fit into a perfect harmonic series. This revelation not only validated the expertise of Indian artisans but also posed further questions about the underlying mechanism.

The secret to the tabla’s unique sound lies in the syahi, a dark paste of iron oxide and starch applied in layers on the drumhead. This added weight and careful distribution of material redistribute the vibration patterns, allowing selected frequencies to reinforce one another, hence producing clear musical tones instead of chaotic noise.

Despite the absence of formal acoustic theory in its development, the craftsmanship behind the tabla represents a sophisticated understanding of sound acoustics that was achieved through generations of meticulous listening and refinement. Modern analyses have confirmed Raman’s initial discoveries, demonstrating the enduring accuracy of this traditional technique.

“I am planning to make a law that horns of all vehicles should be in Indian musical instruments so that it is pleasant to hear. Flute, tabla, violin, harmonium,” Gadkari was quoted as saying by news agency PTI.

Similar proposal by Gadkari earlier

This is not the first time that Gadkari has proposed such a law in the country. In 2021, the minister had said he was planning to introduce a law to make sound of Indian musical instruments mandatory as a horn for vehicles.

India earning significant revenue from automobile exports

Gadkari also highlighted the strength of India’s automobile industry, noting that the country earns significant revenue from the export of two-wheelers and cars. He shared that the industry, valued at Rs 14 lakh crore in 2014, has now grown to Rs 22 lakh crore.

Furthermore, he announced that India has overtaken Japan to become the third-largest automobile market globally, after the United States and China.

Govt of India trying to reduce air pollution caused by transport sector

Gadkari also highlighted that the transport sector is responsible for 40% of the country’s air pollution. To combat this, the central government is actively promoting the adoption of green and biofuels such as methanol and ethanol for vehicles.
