Koor&Stem vzw

What Koor&Stem vzw does

Koor&Stem vzw is the Flemish choral federation headquartered in Antwerp, Belgium, operating as a non-profit association (vzw) under Belgian law. It serves choirs, conductors, primary schools, people with dementia and their caregivers, and individual singers across the Flanders region, functioning as the recognized sector organization for collective singing under the Flemish government's Participatiedecreet. Previously known as Koornetwerk Vlaanderen, the organization rebranded and operates an integrated portfolio spanning the Twizzit cloud-based member management and CRM platform (with Piano, Forte, and Fortissimo add-on modules), the Koorklank digital sheet-music platform, a webshop selling sheet music and educational materials, and a calendar of 945+ training and event listings.

The business model blends recurring membership fees (four tiers: non-insured, BA-insured, LO-insured, and BA+LO-combined) with one-time webshop sales (sheet music, CDs such as the De Stem van ons Geheugen dementia series, Doewap school materials), paid training and workshop fees, festival and event revenue (Koor&Stem Festival, Start to Sing, ZINGMAMEE, Europa Cantat Junior, beVOICEd), and government subsidies. Signature programs include De Stem van ons Geheugen (singing with people with dementia, reaching over 75% of Flanders' 855 residential care homes), Doewap (school singing), Unmute (singing in special-needs youth care), and koorcoaching services. Distribution is primarily direct-to-member and direct-to-consumer via the website, supplemented by regional ambassadors deployed across Flemish sub-regions since early 2025 and partnerships with BOZAR, A Cœur Joie, Födekam, Expertisecentrum Dementie Vlaanderen, SEMU, De Federatie, and music publishers.

Scale indicators5 records

Recent moves7 records

Expansion highlights6 records

Emerging players

• Zangzaam (Stichting Zangzaam): Dutch foundation promoting healthy singing across age groups, with notable programs in singing and wellbeing for older adults. Comparable in mission to Koor&Stem's wellbeing-focused De Stem van ons Geheugen initiative, though operating at smaller scale and without the broader federation scope.
• Sing Up: UK charity driving school singing with structured curriculum materials, teacher training, and the 'Sing Up Award' for schools. Closest international analog to Koor&Stem's Doewap program and a useful peer for benchmarking how a singing-in-schools program scales into a national movement.

Direct peers

• A Cœur Joie: Belgian Francophone choral federation serving Wallonia and Brussels with a parallel mission to Koor&Stem — choir membership, training, festivals, and repertoire support. The two federations already co-operate on the Let's Zing Ensemble and Singing Brussels projects with BOZAR, making them direct structural equivalents in the Belgian choral ecosystem.
• Musique & Santé: French nonprofit developing singing and music programs in healthcare settings — including hospitals, retirement homes, and dementia care. The most direct international analog to Koor&Stem's De Stem van ons Geheugen program, addressing the same singing-with-dementia niche with research-backed methodology and caregiver training.
• Sing for Pleasure: UK-based choral charity running conductor training, festivals, and youth choir development with a comparable training-plus-events business model to Koor&Stem's conductor formation and Koor&Stem Festival offerings.
• Vlamo vzw: Flemish federation for amateur music ensembles (instrumental and other vocal groups), operating an overlapping constituency in Flanders. Collaborates with Koor&Stem on SEMU licensing and COVID-era advocacy, and shares the same member-management, insurance, and training value proposition for amateur music groups.

Regional players

• Koorplein / Koornetwerk Nederland: Dutch national choral network supporting amateur choirs, conductors, and repertoire in the Netherlands. Highly comparable in mission and operating model to Koor&Stem but serving a different linguistic/geographic market, making it a structural cross-border peer rather than a direct competitor.

Broad incumbents

• Chorus America: US national service organization for choral groups, providing advocacy, research, professional development, and convening. Closest structural analog to Koor&Stem outside Europe — comparable federation-plus-services model serving amateur and professional choirs within a defined national/linguistic constituency.
• European Choral Association - Europa Cantat: Pan-European umbrella for choral organizations, of which Koor&Stem is a member through its Europa Cantat Junior hosting role. Comparable in mission (cross-border choral development, festivals, youth) but operates at international rather than regional level and does not run day-to-day member services for individual choirs.
• De Federatie (Vlaamse Federatie voor Amateurkunsten): Flemish umbrella federation for amateur arts organizations, of which Koor&Stem is a member. Coordinates cross-sector advocacy, surveys, and government dialogue — comparable in its federation role but broader in scope (covering music, theater, dance, visual arts) and complementary rather than competitive with Koor&Stem's choral specialization.
