Saxophone Quartet
PROFILE
Founded in 2007, Quatuor B brings together Sadahito Kunisue (soprano), Masaya Yamaura (alto), Sumichika Arimura (tenor), and Gentaro Koyama (baritone). The name reflects a shared coincidence: all four members have blood type B. The quartet performs throughout Japan and abroad, presenting repertoire from classical masterworks to approachable concert programs for schools and communities.
