DESC: 44 bar single row Studio Chimes made by TreeWorks. In studio settings or for acoustic performances you're looking for a less aggressive sound and clear resonance. TreeWorks' Studio Chimes utilize the same T-6 tempered, custom aluminum/ titanium alloy bars in a thinner, .25" diameter. Has a black walnut mantle, and features TreeWorks CordLoc cords which are very strong, hand tied, locked, and sealed so that they won't break or affect the sound.
