Cheers erupted across the GrandWest Grand Arena on Saturday as 1,276 young marimba players officially smashed the Guinness World Record™ for the Largest Marimba Ensemble ever recorded — more than doubling the previous record of 505, set by Guatemala.
The historic performance brought together learners from over 70 schools across South Africa, as well as two schools from Zimbabwe. Themed “United in Harmony”, the attempt was the culmination of years of planning by Marimba Jam, a non-profit founded by Kiara Ramklass, with support from GrandWest’s Social Economic Development team.
“South African marimbas are tuned in C major – it’s almost impossible to feel sad when you hear them. They create this magical, happy energy. That’s what we’re sharing with the world on the 2nd of August,” said Ramklass, who fell in love with the instrument as a schoolgirl 18 years ago.
The ensemble, which ranged in age from 8 to 62, performed a ten-minute medley of “Waka Waka” and “Jerusalema”.
“This event is more than just breaking a record,” said Ramklass. “It’s about showing what’s possible when we come together across socio-economic divides – private schools, township schools, rural schools – all on one stage. It’s a loud, joyful message of ubuntu.”
The record was confirmed on site by an official Guinness World Records™ adjudicator who flew in from London. Every participant received a medallion marking their part in the achievement.
Western Cape Premier Alan Winde joined the celebration, posting:
“Today, Western Cape schools officially made history with the largest marimba ensemble ever recorded – 1,276 talented young people drumming as one! In a moment of profound unity, learners from Zimbabwe and South Africa worked together to achieve this stunning win. I’m incredibly proud of our province for playing host to this piece of history. To every learner, educator, organiser and supporter: this is your victory! Thank you for showing the world what’s possible when our youth rise to the occasion. Proudly Western Cape. Proudly record-breakers.”
