The low whistle is an instrument highly appreciated in traditional music circles and particularly Celtic music. However the noise level is often considered insufficient, especially in sessions.
To increase the sound volume I was inspired by the Quena flute which is well known for its sound volume. The combination of a low whistle in aluminium with a notch style embouchure gives the whistle extra volume. The characteristics obtained are remarkable with excellent dynamic performance and subtle tones and variations giving a sound going from pure and round to a one which can be altered at will. The sound is similar to that of the low whistle whereas its playing technique is close to that of the flute.
I have called this new instrument the Open Whistle.
The embouchure may seem like an obstacle in the beginning but in fact with a little practise you will soon be producing a full and powerful sound.
