As the vocal and performance powerhouse MAMAMOO approaches their landmark 10th anniversary, we reflect on their journey. This journey has been marked by countless iconic performances, chart-topping releases, and a deep connection formed with their fans. Consistently, MAMAMOO has been acclaimed for their energetic stages and robust live vocals, earning them the nickname "BeLisMAMAMOO" (Believe and Listen to MAMAMOO) from the Korean general public right from the start.

The industry insiders, from fellow musicians and MCs to the general audience, all agree: MAMAMOO's live vocals are exceptionally stable and have only improved over time. Their natural talent is evident, but it's the relentless practice behind the scenes that contributes to their consistent vocal excellence.

In an intimate revelation on "MAMAMOO Drinking Season 2," leader and main vocalist Solar shared the group's pre-debut struggles, "Before our debut, we faced skepticism due to our appearance. Critics would say, 'They’re going to flop because they’re short and don’t look like idols.'" She continued, "The pressure to be perfect was intense, with many predicting our failure unless we delivered flawless performances." This only fueled their determination to excel live on stage, where giving anything less than 120% was never an option.

The secret behind MAMAMOO's extraordinary vocal control is rigorous practice, combining full choreography runs with intensive vocal drills. This included singing while engaging in physical activities like running, squatting, and lunging to ensure they could maintain control under any circumstance.

Years of dedicated training are showcased in their practice videos, where they perform complex choreography while nailing every note. Recent behind-the-scenes footage from Wheein and Moonbyul exhibits their training regimen, singing live and on key while exercising. This commitment was spotlighted when Solar expertly regained her vocal composure after a brief slip during their "Queendom" performance of "Good luck" – a testament to their unwavering dedication to vocal mastery.

MAMAMOO's commitment to vocal excellence is further evidenced by the practices of their youngest member, Hwasa. She has previously shared in interviews that her training regimen included singing while engaging in physically demanding activities, such as running or performing lunges. This rigorous training was on full display during an encore stage of her hit song "Twit," where Hwasa maintained flawless vocal stability even while carrying the weight of the other three MAMAMOO members on her back, not missing a single note or key.

The group's leader, Solar, echoes this dedication to practice. She has taken the concept of singing under duress to new heights, as demonstrated during the group's 2018 tour. Solar showcased her ability to deliver live vocals while performing complex physical tasks, such as singing the cover of "Despacito" while hanging from a pole, proving that MAMAMOO's vocal stability remains unrivaled, even in the most unconventional of situations.

The cornerstone of MAMAMOO's vocal prowess is not so much a secret as it is a universally acknowledged truth in the pursuit of excellence: consistent practice, ideally under the guidance of a vocal coach. It is well-known that since their debut, the members have dedicated themselves to refining their vocal skills both individually and with the aid of professional coaches. The group's rapper, MoonByul, has openly shared footage of her vocal coaching sessions, especially during her stint on the survival show "Second World." Her commitment to vocal development was rewarded when she emerged victorious in the show's vocal competition. She has candidly attributed her ongoing vocal evolution to her continuous work with a vocal coach, a fact she proudly reiterates in her 2024 album "Starlit of Muse."

Beyond dedicated solo practice and expert guidance from vocal coaches, MAMAMOO has cultivated a unique harmony since their debut that extends outside of formal performance settings. Whether it's during rehearsals, fan meetings, karaoke sessions, or simply impromptu gatherings, the four members seize every opportunity to blend their voices in harmony as if it were their final performance. This instinctual synchronization ensures that any member can seamlessly adopt another's part in a song, maintaining impeccable pitch even amidst the roar of the largest concert venues.

So, while the secrets to MAMAMOO's live vocals may not be that big of a secret anymore. The group's vocal talent in the 10th year of their debut anniversary has never been better.
