Sankyo is a flute manufacturer founded in Japan in 1968. With its exquisite design and rigorous workmanship, it is favored by world-famous flutists such as Alain Marion, Langson Wilson, Marzio Conti, Antonio Arias and others. Sankyo was not only a pioneer in the use of high-purity silver alloys, but also the first manufacturer in the world to introduce a 24-karat gold flute. Sankyo has designed all of the flute's mechanical systems, mouthpiece joints and specialized system equipment, including the provision of split E mechanism, needle-free system and NEL design, creating the revolutionary Gema system and complete multiphonic pore device. It also produced a D'amore-style A-key flute that fills the gap between the alto and the regular C-key flute, and its mouthpiece is also quite distinctive, offering a total of 6 options of ST1, 2, 3 and RT1, 2 and 3, with the RT1 being the most representative. Sankyo's representative model Aritist CF401, priced at about 56,000 yuan, sterling silver handmade mouthpiece, pipe body and buttons, the new built-in E key split, flexible and accurate high-bass conversion, soft and pure timbre, is a high-quality choice for soloists. It is worth noting that the three-piece flute is very exquisitely crafted and has a beautiful design, but its volume is generally on the low side, which is not suitable for playing with a wind band.
