Debjit Mahalanobis was just another name in Quashik Mukherjee’s Facebook friends list. That is until the Bengali filmmaker popularly known as Q came across a video of Mahalanobis playing the double bass in jugalbandi with the sitar in November 2018. Q was intrigued. He was searching for theme music for his web series Taranath Tantrik. “I always try to work with whatever is available around me,” he said. “I was thrilled to find out that someone plays the double bass this well in Calcutta.”

Two weeks later, they met at a studio in Keyatala Road in South Kolkata – Q’s “usual spot”, where he has recorded almost all the music for his films. “He was generally fiddling with the instrument when he played what is now the main melody of the title track,” recollected Q. “We recorded it right there.”

The teaser trailer of Taranath Tantrik, released on January 7 on YouTube, gives a glimpse of the title track, which is heard every time the protagonist Taranath, an occult practitioner, appears on screen. “It’s the track that announces that Taranath is embarking on an otherworldly expedition,” said Q.


The three-and-a-half-minute title track features five layers of double bass. A double layer of melody is bowed in on a setting of low drones and short, sharp arcos. “This phrase [dual melody] actually [refers to] the same melody played in two different pitches,” explained Mahalanobis. “When heard together, they sound a little out of tune, creating the ominous effect.” There is no pizzicato, or plucking, in the piece. The entire track creates a sense of impending doom, which is heightened by the jerky nature of the often-eerie visuals of the series. Taranath Tantrik is the first Bengali series to feature a double-bass-driven title tack.

The web series is based on a character created by Bengali novelist Bibhutibhushan Bandyaopadhyay in the 1940s and carried forward by his son Taradas Bandyopadhyay. “The character Taranath is less haunting and lighter in the book than in this adaptation,” said Mahalanobis. “The way Q introduced him led me to this dark melody that we recorded around midnight.” The evening when Q described his vision of Taranath to Mahalanobis, the two were seated in the garden outside the studio, talking about black magic and aghoris, as a light bulb flickered in a dark corner. Taranath Tantrik, which features 10 episodes, was released on the video-on-demand site Hoichoi on January 19.

The double bass is the largest of all stringed instruments – almost double the size of the cello – and there are very few professional artists playing it in India. Mahalanobis’ love affair with it started in 2006 when he was 17. “I used to play the bass guitar in a band in school,” he said. “The double bass, which is considered the toughest to play because of its size, felt like a challenge to me. I took it up because I wanted to understand the roots of bass.”

For about six years, Mahalanobis had no instrument of his own because it wasn’t being imported to India. He would go to the home of his teacher, celebrated music conductor Abraham Mazumder, every time he wanted to practice. This changed when he met a luthier who agreed to make the instrument with the bridge and neck adjustments Mahalanobis needed. It took them three years to get the combination of wood right to make sure that the fretless fingerboard doesn’t bend due to moisture.

Though music was his passion, the luxury of making it his day job came much later. After a master’s degree in computer application, he joined a private school in Kolkata as a physics teacher in 2013. “I don’t come from a family of musicians,” he said. “It was important for me to earn a living after finishing college, and I didn’t want to become an information technology professional.” The teaching job came as a blessing because not only did he enjoy it, the school holidays and convenient timings gave him ample free time to practise his music.

For about three years, his life followed a predictable but busy routine. He would finish teaching at school, practise the instrument, learn music reading and writing at the Abraham Mazumder Academy of Music, and perform with his orchestra. “I felt like I was leading a dual life,” he said. “After a point, I realised my true calling is music. I didn’t want to regret not being serious about it when I’m 40.”

Mahalanobis quit the teaching job in 2015. The following year, he formed a jazz band called Cadenza with two musicians he had met at the Calcutta School of Music. This marked the beginning of his experimentation with other genres, and since then, Mahalanobis has been infusing the rich, demanding sound of the double bass in electronic music, folk music, Bollywood music and compositions of Rabindranath Tagore. The most unique of his experiments, however, are with Indian classical music. In a couple of collaborations with sitar player Snehesh Nag, Mahalanobis played the taanas on the double bass complementing the sitar, just like in a traditional jugalbandi. He never deviated from the note structure of the raga, and often filled up the pauses of the sitar. “I want to use the double bass prolifically as a dhrupad instrument,” he said. “It has suitable depth and patience.” In a bid to expand his musical repertoire, Mahalanobis started studying Hindustani classical music with sarod maestro Prattyush Banerjee last year.

Innovative sounds

His unique place in the music world – Mahalanobis is the only full-time professional upright double bass artist in Bengal – has afforded him the opportunity to pair up with a cross-section of artists and create some innovative music.

In 2017, Mahalanobis appeared as a guest on the popular music reality show Sa Re Ga Ma Pa on Zee Bangla. The same year, he gave a sufi performance on television with the music collective Murshibadi Project. Another achievement was playing the double bass with a Bangla song for Friday Night Originals, a YouTube channel that tries to “bring independent music into the limelight”.

In 2018, Mahalanobis formed a group with electronic music producer and sound synthesist Varun Desai called Strings and Circuits. They were joined by Dibyakamal Mitra on the violin/mandolin. Their music explores the intertextuality of digital and analogue. They say they are working on an EP, which has got “sounds that are very emotive and would fit well in a film score with an electronic ambience,” said Desai.

One of Mahalanobis’ most memorable compositions, a collaboration with vocalist Malini Banerjee, featured a song written by Tagore. This was the first time a Rabindra Sangeet was arranged with just the double bass. This collaboration finally culminated in a bolly-jazz band called Mixed Signals, which performed in December 2018 at The India Story 4.0, the fourth chapter of a yearly exposition that brings together lifestyle, food, design, arts and music performances. The band continues to recreate popular Hindi numbers by giving them a jazz twist.

Taranath Tantrik is Mahalanobis’ first big project, and it made him realise he is on the right track. “I used to put up music recordings on Facebook after working on it for 3-4 months and get around 30 likes,” he said. “It would leave me feeling a little unsure, but thankfully I never gave up.”
