The Low D Qwistle is a strong & warm sounding low whistle, pitched in the key of "D", and designed by Scottish musician & instrument innovator Donald WG Lindsay (donaldwglindsay.com).
The Low D Qwistle's simple construction also makes it one of the most lightweight low D's around, weighing in at only 5 ounces for the aluminum model.
Approximately 22 1/8 inches long.
The Low D Qwistle is tuneable within a range of +/- 12 cents, and combines a strong, assertive sound with good intonation, and warmth of tone.
The "Standard" is a comparatively strong low whistle, with solid low notes, and a "thick" tone with strong fundamental and good volume balance between octaves. Air efficiency has been improved for May 2018, and compares well with other professional standard low D's.
The "Pro" mouthpiece will take a little more "push", particularly in the second register, and has a little more of everything listed above (ie. everything that characterises the Qwistle), including a bottom D you can basically bounce off the wall.
Made in the UK, the Low D Qwistle is manufactured to a high degree of precision, using a combination of cutting edge 3D printing and traditional machining skills.
All Qwistles are personally finished, adjusted, tuned and tested by Donald WG Lindsay at the Lindstruments workshop in Glasgow.
