A small, hard, high and vociferous harp. The cod is practically invisible, but on a relatively even background there is a rustle of the finger and springy high-frequency sounds when striking the tongue. The timbre is not harmonious - the overtones are mixed in random proportions into one, beautifully sparkling, mass. The volume rises smoothly and is well controlled from small to very high; with the approach to its upper limit, the voices begin to shift into some kind of general trembling. If you do not find fault, then for your price, the combination of the basic parameters is unique. Instrument for expressive, constantly colorful playing without using much of overtones.
