Largest cumulative attendance for a singing lesson at a single venue

The largest cumulative attendance for a singing lesson at a single venue is 1,881,100 and was achieved by KBS Busan Singing Class (Republic of Korea) in Busan, Republic of Korea from 13 August 2013 to 24 June 2026

Launched in 2004, the KBS Busan Singing Class is an annual cultural programme organized by the regional broadcasting hub KBS Busan. The aim is to engage local citizens through singing - a project that has expanded in size and reach over the years.

At the heart of it all is instructor Sung-hwan Yim, who has led the classes with infectious enthusiasm for years. "This is a job I was destined to have," he told Guinness World Records adjudicator Mingyoung Sohn. True to form, when KBS Busan dedicated the annual record to him personally, he immediately redirected the honour. "The participants are truly the record holders," he insisted.

The record - plus a second title, for the largest annual attendance for a singing lesson at a single venue (210,989 people in 2025) - was revealed at the opening ceremony of the programme's landmark 100th batch, giving organizers, staff and thousands of loyal participants the chance to celebrate together. Guinness World Records' Mingyoung described the atmosphere as electric. "The energy from the crowd was incredible," she said. "The deep connection between the instructor and participants was plain for everyone to see."

Designed to boost community morale, and open to all Busan citizens, the class has become a cherished weekly ritual, particularly among the city's elderly residents. Acheiving these two Guinness World Records titles is their reward for showing up, week after week, and singing their hearts out.
