Founded in 1954, Aulos is a brand of Toyama musical instruments in Japan, and its products are sold in more than 50 countries and regions such as Britain, France, Germany, Italy, Australia, and the United States. In 1966, Aulos produced the world's first ABS resin flute, followed by the world's first bass resin recorder in 1983. In addition, Aulos has creatively created a recorder specifically designed for people with disabilities, with adjustable recorder holes. Aulos and Yamaha are on a par with the rubber flute, just like MOECK and Mollenhauer are to the wooden flute, taking the recorder as an example, Taiwan is highly developed and moving towards specialization and symphony, and the two brands with the highest frequency and best evaluation in the straight flute orchestra and straight flute solo are Japan's Aulos and YAMAHA. Aulos' 503BE tweeter and 509BE alto flute are both very cost-effective and more expensive than YAMAHA.
