Even though Irish flutes have been around for centuries, they still haven’t their touch because of they’re enduring qualities that differ them from more contemporary instruments.
Most Irish prefer the simple-system flute, especially a wooden flute type. However, recently, others have developed a liking for flutes of Boehm-system type, which is somehow reminiscent of a contemporary metal flute.
The Internet is a rich source for manuals and tips on how to select and use the right kind of simple-system flute. Such manuals and tips also contain instructions on the appropriate keys and tuning depending on the applicable factors.
