What Clac does

CLAC vzw is a Belgian non-profit percussion music school headquartered in Rumst (Terhagen) with an additional training site in Antwerp. The organization delivers rhythm-based music education to children, youth, and adults using a proprietary pedagogical approach branded as 'The Language of Rhythm' (CLAC Method), which treats rhythm as a universal language rather than relying on traditional music notation. Founded more than ten years ago by percussionists Chryster Aerts and Bart Van Aken, CLAC currently operates from leased training facilities at DKO muzische school in Antwerp and Sportcentrum 'Uitgedekt Schoor' in Terhagen, with an additional venue at Vrije Basisschool Sleutelhof in Rumst for its vacation camps.\n\nThe service portfolio centers on weekly djembe and drum lessons structured in trimesters of ten sessions each. Adjacent revenue lines include a broad workshop catalog covering West African, Arabic, Brazilian, Latin-American, body, and ECO percussion styles; corporate teambuilding sessions priced from €15 per person; three-day Easter and summer vacation camps for children aged 5-12 priced at €90 per child; custom pedagogical projects for schools and organizations; an instrument repair service for djembes and doundouns; and an online video lesson library. Artistic output is delivered through three sub-brands: Kaboon (a world-percussion ensemble established in 2010), the CLAC Streetband (mobile event animation), and Young CLAC Band (youth ensemble).\n\nCLAC's go-to-market is community-led and event-driven. The organization maintains active organic social channels on Instagram, Facebook, and YouTube and circulates an email newsletter for course promotion. Public visibility is reinforced through recurring performance engagements at marquee Belgian events including the Brussels Marathon, Antwerp 10 Miles, Antwerp City Drops, and C-Mine Genk. CLAC employs approximately 15 instructors supported by administrative and communications staff; no external funding, M&A, or institutional ownership is disclosed.

Regional players

• Koninklijk Conservatorium Antwerpen: Royal Conservatory of Antwerp (part of AP University of Applied Sciences) is a broader music education institution serving the same Antwerp region as CLAC, offering instrumental and ensemble training. Comparable as a regional music education incumbent, though it operates at a much larger academic scale.
• Academie Hoboken: Municipal music academy in Hoboken (Antwerp region) where CLAC co-founder Chryster Aerts serves as artistic director. Operates a broader instrumental curriculum within the Flemish DKO system that CLAC supplements with percussion-focused programming.
• Percussie Punt: Belgian percussion retailer and workshop provider serving the Flemish market with djembe, conga, and world percussion retail plus lessons. Comparable as a regional competitor in the Belgian percussion-instruction niche, though anchored in retail rather than a dedicated school.
• Drumschool.nl: Dutch online and in-person drum school offering lessons and workshops. Comparable as a regional drum/percussion instruction provider in the Benelux, though broader in style (drum kit focus rather than world percussion).
• Muziekschool.be: Aggregator platform listing Belgian music schools and instructors across all instruments. Comparable as a regional distribution channel for music instruction in Belgium, though it operates a marketplace model rather than direct instruction.

Direct peers

• TaKeTiNa: Austrian-origin rhythm education method developed by Reinhard Flatischler that teaches musical rhythm without notation, focused on group learning. Highly comparable to CLAC's 'Language of Rhythm' pedagogical philosophy and group-workshop delivery model, though operating internationally as a method-licensing organization rather than a single local school.
• Drum Café: South Africa-origin company offering interactive drumming events and team-building using African djembe-style percussion. Directly comparable to CLAC's teambuilding offering and event-animation sub-brand (CLAC Streetband), though Drum Café scales internationally through franchises.
