Patent filed by Sempiternus Snare Drum by Sergio Giovagnola
VAT ID: 01942620434
The innovative Sempiternus Italian brand snare drum with its patent guarantees uniqueness and protects the unmistakable craftsmanship of luteus Sergio Giovagnola. It is a technology that has never been realized b
efore, according to which, with heat generated by water steam, a solid wood board is manually bent, thus obtaining a perfectly cylindrical drum that does not require the use of glue. After bending, the stem can be considered finished so the fibers and the grain of the wood do not undergo any other type of work stress such as, for example, internal and external turning. Subsequently, in the snare drill, bent by 45 °, solid wood tiles are placed in the same process as described above. They provide strength to the edges of the stem, where strength is fundamental since, during tuning, the skins force those areas to deform in diameter due to the strength and weight of the tie rods. Once the internal reinforcements are installed, 12 "SOULS" are placed, 10 for the tuning tie rods, and 2 for the Throw-Off mechanism, previously selected based on the perfect verticalness of the grain. The "SOULS" are used to connect the resonance ring with the resonant, just as it works in the harmonic case of arched instruments, where the "SOULS" connects the table with the bottom. They also send the sound wave from the skin to the resonant as if it is guided on track, without any decrease in intensity and frequency variation. The harmonic case vibrates homogeneously across the entire perimeter of the stem thus generating a unique timbre note obtained precisely from this unique construction method that allows in this way to "extrapolate" the specific "voice" of the essence with which are constructed the barrels. The so produced note, powerful and dominant by volumes without equals, enriched by attractive harmonic nuances, make the excellent SEMPITERNUS snare unmistakable.
