The jawbone of a horse or mule that was the prototype of my first invention,
Vibra-Slap®. It wasn't until a few years AFTER I created Vibra-Slap
I saw the original version. The creation came about by trying to duplicate
what drummer/ percussionist, Bob Rosengarden described as the way that
the jawbone created the sound. Quijada de Burro, from the collection of
Nicolas Quintana, friend of Fernando Ortiz.
