Distilling the expertise gained through 30 years of triangle making, Grover created its new Bronze Hammered Lite Triangles. BHL triangles are hand-shaped from a special 3/8-in diameter alloy. The proprietary alchemy of these highly resonant triangles is integral to the sonic properties and is a closely guarded secret. Each BHL triangle is hand-hammered in a randomized pattern, which enhances the production of primary and secondary harmonics. The tonal properties can best be described as resonant with a very wide array of audible harmonics. These instruments produce a lighter sonority than Grover Bronze Pro Hammered series, yet they retain the distinctive and complex harmonic spectrum for which Grover hammered triangles are renowned. Available in sizes 4? – 9?, BHL Triangle is ideal for professionals and percussionists who desire a triangle with a full overtone spectrum, yet lighter and more sensitive sound profile
