Founded in 1927 in the United States, Powell is a well-known brand whose hand-made flutes are considered the "gold standard" in the flute world, and are used by famous musicians such as Ian Anderson, Catherine "Cady" Coleman, Jethro Tull, William Kincaid and Roberto Alvarez. The Powell flute, played by renowned flutist William Kincaid, was successfully sold for $170,000 at Christie's. Powell is also the world's most used brand for professional orchestras, with its flutes featuring hidden adjustment screws, hand-crafted mouthpieces, and a patented Zinki(TM) sound sequence design technology that has been emulated by modern flute techniques. Powell flutes are mainly divided into Signature series, Conservatory and Powell Custom classic series, the representative model Signature HC, handmade mouthpiece and G sound hole inset discs, responsive keys, bright treble and thick bass, accurate and natural range switching, priced at about $7,000. In addition, the Sonare series made by Powell in Germany has similar material functions to the American ones, and the price is relatively affordable, so if you are a beginner and don't want to invest too much financially, then Sonare is also a good choice.
