All my bridges are designed and cut based on original models, developed by me, and are individually conceived for each contrabass.
Throughout the course of my career, either as a musician or as a luthier, I have used almost all types of bridges. I’ve always liked the French and Belgian bridges most, both for their timbre and aesthetic qualities.
There are some substantial differences between bridges of the Belgian style and the others, whether French or German, to mention the most popular. Bridges of the Belgian style have a small body and legs that are quite long and thin. The others have bodies that are relatively larger, and shorter legs. The French bridges have eyes that are larger and more elongated, the German ones have smaller, rounder eyes. All these are details that make a big difference in how the instrument ends up sounding.
I’ve always verified the thesis that there is no such thing as the definitive bridge for any instrument, for all situations. In fact I’ve found that it’s quite the opposite. Sometimes it is necessary to exchange the bridge when the instrument changes hands, perhaps because the musician needs a another timbre for a repertoire different than the previous owner’s, or in order to compensate for differences in playing technique.
Whatever the function of the instrument, it is always necessary to achieve the maximum output and I like to do this by tying captivating lines with proven technical choices. In my view, it is vital that the bridge be beautiful, that it has sufficiently long legs and a balanced and elastic center, in order to produce a powerful sound and to adequately filter the harmonic content of the strings. I guarantee that I work with various thicknesses and proportions, and it is possible to drastically alter the timbre and sometimes the general output of the instrument.
I truly believe that working with different thickness and proportions is possible to dramatically tweak the sound and whole feeling of an instrument.
My model bridge was conceived initially using the same construction tools that I use for my contrabasses. Therefore, it is easy to find in it elements of the golden ratio and Renaissance notions of equilibrium. This side image shows a sketch, from my model template, demonstrating how simple it is to find this information in my design...
Each line is intersected by a point that precisely demarcates the golden section.
It is possible to notice how carefully I work to harmonize the eyes with the body of the bridge, even when using a conventional design and in this case the Belgian style. A perfect circle tangentially intersects the principal points of the form: the center of the table, the nubs of the legs, the upper border ot the eyes and the crest of the heart.
Para obter o melhor resultado possível, para cada contrabaixo estúdo as medidas e as formas mais oportunas. Às vezes, é oportuno esculpir dois ou até três cavaletes para uma única montagem, para descobrir o cavalete mais adequado.
A madeira joga um papel fundamental nisso, e sempre tenho um vasto estoque de acero (maple) para esse propósito. Procuro a melhor madeira disponível para isso, e costumo ter três tipos distintos de madeiras:
