TreeWorks Made In the USA Studio-Grade Triangle Set with Beaters & Bag - TreeWorks is a small company in Nashville, Tennessee that specializes in handcrafting chimes for drummers and percussionists. They used their extensive knowledge in metallurgy and heat treatment, plus many hours of testing prototypes to create these studio-grade instruments. They even experimented with the radius of the bend for changes in timbre. Their triangles begin in a raw bar stock form. This ultra-hard high carbon steel alloy is needed to create the clear tone. The sound is further refined by the heat treatment which brings out a shimmering spread of frequencies. A satin chrome finish protects the triangle and is intentionally thin in order to not adversely affect the sound. Three full-size professional triangle beaters are included. They are made of solid stainless steel and have a non-slip color coded grip. Each is a different weight, from light (3/16") to heavy (1/4"), allowing you to create just the right volume and tonal color. The set includes three triangles: 4-inch, 5-inch and 6-inch, four full-size professional stainless steel triangle beaters with non-slip grips and a compartmentalized bag to keep it all organized.
