After more than two decades of observations at several factors implied in Classical Guitar Technique, Humberto Bruni developed several devices that help develop finger independence. 

Finger independence is a success key factor for playing the uttermost difficult works written for the instrument. Some of those pieces are simply unreachable for thousands of Classical Guitar players around the World.


Right now, those inventions are in the process of Research, Development and Testing.


The most conspicuous of those inventions is the "CG-Pal", which according with the scientific data acquisition during strictly controlled experiments, have proven great efficiency with satisfactory statistical significance.

In a near future, (end of year 2022), the results as well as the first working prototypes will be shown in this section.
