established in 1999, quatuor de saxophones diapason is headed by yan kuo-cheng and composed of 4 distinguished musicians in taiwan, all of whom were awarded with the first prize performance diploma of the advanced class by french conservatoire de rueil-malmaison. the band is led by yan ching-hsian with three other members: chang chia-hung, wang tzu-hao, and chen cheng-yu.
due to the increased population in studying and appreciating saxophones, there are a great number of professional ensemble bands of saxophones in the globe, some of which have been well-established and highly regarded for years. it's a pity that asia has a late start in this kind of development so that there is lack of saxophones musicians, instructors, and of course, professional saxophones bands. under this circumstance, the four professionals decided to form a high-standard quartet band of saxophones, aiming at "promoting the musical level in saxophones and marching towards the international stage of musical performances" and hoping to make some dedication to those in love or study of saxophones.
diapason has performed around the globe in such countries as singapore, korea, china, france, united states, and so on. both the artistic depth and the broad scope of their performances have gone beyond the general categories of classic and modern saxophones quartets. in addition, many renowned song writers, after listening to their performances, composed their own quartet creations for diapason to perform. they included the famous conductor and composer across the straits, qu chun-quan, leader of taipei chinese orchestra, chung yiu-kwong, the best musical arranger winner of golden melody awards, chung hsing-min (jay chou's special musical arranger), and so on. the inventory styles range from the classic, chinese traditional music, taiwan native and folk music, modern avant-garde, and popular jazz, to those exquisite pieces of cross-over music.
diapason has recently accepted many invitations for performances in the announcement campaigns on behalf of such celebrated brand names as cartier, mercedes-benz, volvo, and others for their famed products like the panthere de cartier jewelry collection, cls model, musical banquets, and so on in 2004. it is proved that the exquisite art of quatuor de saxophones diapason has been confirmed by world-class brand names.
