TreeWorks Chimes" Double Triangle is one continuous piece of hardened alloy steel. It combines a traditional 4-inch triangle with an 8-inch tall version of TreeWorks" unique Steeple Triangle. It can be hung with either triangle on top. This unusual combination encourages you to explore the many tonal possibilities from playing the closed vs. open sides, to the varied angles at the top and bottom. The sound of the steel alloy is refined with a high temperature heat treatment, which brings out the brilliant response. The ultra-thin satin finish protects the triangle but is so thin is does not impede the sound. Comes with a full size professional stainless steel beater. In the summer of 1996, TreeWorks Chimes was created by Mitch McMichen. It began in his garage in Nashville, Tennessee. The first set of chimes was made with a hacksaw and a hand drill. It didn"t look like much, but that was the first step to crafting the perfect set of chimes. When asked about the early days of TreeWorks, Mitch replies, "I wasn"t trying to start a company. I was trying to find a sound." Since then TreeWorks Chimes has grown to become the most respected chimes in the percussion world - used by top studio and touring drummers and percussionist as well as the top 24 drum corps. These instruments are still handmade in Nashville, Tennessee and are unmatched in craftsmanship and sound quality. (It is of note that Mitch McMichen has earned Gold and Platinum records for his recording work in Nashville.)
