In Celtic music, whistle players begin to appear in 11th Century literature and art. There are numerous names for Celtic whistles, including, but not close to limited to: Pennywhistle, Irish Whistle, Tin Flute, Feadan and more. Without regard to the name, they all have six holes and are played by blowing through a mouthpiece. The Pennywhistle is a frequent accompaniment in most Celtic Bands today. They can be simple, or ornate, light in weight and relatively easy to play whether marching or stationary.
