An increased version of the standard jaw harp with the preservation of all its advantages and a decrease in the frequency of sound. The brightest features are a soft, light reed; transparent, chirping timbre and high sensitivity (minimum effort leads to maximum sound). Thick frame arms make you open your mouth a little wider than usual; in terms of mechanics, the instrument is not the most versatile - it is good for a measured playing with simple beats. A great jaw harp for those looking for pure sound for simple play, but not mechanical sensations.
