This article details some of the work involved as well as the final outcome.  \nWe have come to know Leonardo’s character  \nthrough his notebooks which express the unlimited curiosity of a man whose interests ranged from comparative anatomy to painting, and from musical instruments to hydraulic engineering and all kinds of machines. He was a scientist, artist and inventor who did not perceive contradictions between the various aspects of knowledge. His explorations, encompassing  \nevery type of knowledge, were achieved through  \nresearch into new methods and new contents derived from experimentation. He thought that research should be done using mathematical demonstrations and he emphasized the importance of experience. For him, a b s t r a c t concepts  \ncould not be considered real unless they w e r e proven by experimentation.  \nIn his manuscripts, Leonardo writes about the concept of musical mechanisms as applications of mechanical parts of instruments which were not originally mechanical. He first designed rotating cylinders with teeth between 1490 and 1495. The mechanical drum joined this category through the use of the nailed cylinder used in moving the drumsticks (Figure 2) . This mechanism’s evolution led to the development of complete families of instruments.  \nApproximately five hundred years ago Leonardo recorded his design of machinery and his thoughts on how to facilitate man’s work and activities. This way of thinking was new, just as were some specific objects he studied as part of mechanics. Many of his ideas were too advanced for his era and were only constructed many years later. The roots of this current project date back to that time in the late fifteenth century when Leonardo thought of how to avoid that hundreds of drummers (who accompanied the army with the rhythmic sound of drums) died during the battles. So why not make a mechanical device that, pulled by a horse or two men, replaced at least a dozen of traditional drums? Leonardo imagined a system that would make it possible to produce the rhythmic sound with the movement of the wheels by using a crank positioned on the axis of the wheels.  \nFigure 3.
