I place a pair of bones (Black grooved ones) between the fingers on my right hand. The one with the black ends goes between my 3rd and 4th finger. The stationary bone goes between my 1st and 2nd finger. Now I put a pair (Red grooved ones) between the fingers on my left hand. I settle my fingers into the finger grooves in the middle of the bones and relax. As I begin to click, I hear the Bois d'arc bones giving 4 separate clinking sounds. I pick up the rhythm and the beat of the song and then begin adjusting the base/treble sound of the clinking bones. With my middle finger I apply pressure to the stationary bone, holding it against the heel of my thumb. The greater the pressure the more base the sound; less pressure gives more treble. Now I have 4 clinking sounds and an infinite range between base and treble. The finger above my pinkie finger keeps the clicker bone in line with the stationary bone. Consistency in one’s holding of the bones is the key to clicking. Having 4 striking surfaces; with the left hand pair having a different sound than the right hand pair and the ability to vary the tone between bass and treble, moves my bois d'arc bones, with finger grooves, from a primitive instrument into a highly developed musical instrument. It is possible to pick out every note with the piano as the pianist plays a slow gospel number; something not easily done with conventional bones. Just as easy are the complex rhythms of today's country music.
