LP Granite Blocks are the modern-day version of ancient Chinese temple blocks, tuned to a pentatonic scale for playing melodic accent rhythms. With the included mounting hardware, the blocks can be set up five across or in an over/under configuration. The entire unit mounts to nearly any stand that is ¾” diameter or greater. This set does not include the original mallets or the bracket that secures the "five across" set up. One of the mounting screws was lost and replaced with a Rhythm Tech screw that functions perfectly.
