The methodology adopted for instrument building is the result of an intense collaboration between a luthier and an engineer, i.e., Mario Garrone and Dr. Giuseppe Cuzzucoli, respectively.

It was conceived to address the construction with a scientific approach as much as possible, by monitoring board resonances with the aid of appropriate equipment and dedicated computer programs.

These resonances indeed embody the chromosomes that describe the behaviour of an instrument as an acoustic resonator. The verification of their features such as amplitude and position in the frequency spectrum represents a powerful tool to engineer the guitar construction and optimize its final performance.


In order to acquire information on resonances, an acoustic gavel is used to hit the top and back in correspondence of the saddle. Gavel-induced oscillations generate a sound that is recorded and processed by a software. The latter performs the FFT (Fast Fourier Transform) of the signal, determining its spectral content both in linear scale and integrated over one-third octave bands.

Additional figures of merit, which are calculated and assessed, are the sustain of each resonance and the spectrogram so as to analyze how the harmonics vary in time.

The aforementioned analyses are done during each phase of the construction.
