At Milagro we implement our own technologies for the manufacture of musical instruments, using composite materials that we have devised from scratch, developed through acoustic engineering. From materials to the instrument, from matter to shared emotion. Where there is music there is community.
At Milagro we are luthiers by vocation. Our aim is to produce the best musical instruments, in an unyielding quest for acoustic and functional excellence.
As a result of our ambitious mission and our curiosity, and bearing in mind the constraints of working with wood, we uncovered the advantages of composite materials. Today, we implement our own technologies for the manufacture of musical instruments, using composite materials that we have devised from scratch, developed through acoustic engineering.
Our ambition keeps us at the forefront of innovation, especially in three key areas, which are the essence of Milagro:
1) Acoustic research and engineering. Our UHMAA measurement technology gives us an understanding of the acoustic behaviour of materials, enabling us to use our own composite material formulae to create, ensuring we have the best materials for the manufacture of musical instruments.
2) Redesigning musical instruments to extract the maximum acoustic and functional potential from these new materials.
3) The traceability and consistency of our advanced processes for manufacturing composite materials, guaranteeing the excellent acoustic quality of the musical instruments we create.
Wood has traditionally been the most widely used material in the manufacture of stringed musical instruments. After centuries of technical improvements, luthiers have taken the acoustic performance of wood to its limits.
Nothing new can now be expected from wood which, on the other hand, still presents manufacturing drawbacks due to its intrinsic characteristics:
– Low traceability in production and purchase due to irregular growth of the trees and physical differences between one trunk and another This causes variations in quality between different instruments of the same model and makes repairs difficult.
– Wood is highly sensitive to changes in humidity or temperature, which can cause it to physically alter, shrinking or swelling, resulting in loss of tuning and even breakage of the instrument. If wood travels to different climates, an instrument can take up to 48 hours to acclimatise and recover its original state.
Composite materials are the product of blending two or more materials into one, to achieve a combination of their properties that would be impossible to obtain from the original materials on their own.
Our composite materials, Carbon Fibre Acoustic Spine and Linen Fibre Acoustic Spine, are very close to theoretical perfection for the manufacture of acoustic instruments. Their high rigidity and low mass are ideally suited to manufacturing very lightweight sound conducting surfaces that need less energy to vibrate.
In addition, our UHMAA measurement technology gives us a comprehensive insight into the acoustic behaviour of instruments and their materials. This affords us an understanding of any defects and enables us to correct them, to imagine the ideal sound and to achieve it. Through acoustic engineering, we adjust our materials and instruments, working with our own composite formulae, to achieve precisely the acoustics we are looking for.
Greater sustain, volume and sound projection
Our musical instruments optimise the transformation of vibration into sound. So the notes played last longer, and the volume and projection of their sound is greater.
More durability and convenience of use
Our musical instruments are not affected by changes in humidity or temperature. They do not shrink or swell, always maintaining their measurements, so their risk of breakage, bulging or degradation is reduced, and their pitch remains stable under any weather conditions.
Likewise, the string height (or action) on our stringed instruments can be conveniently adjusted, avoiding the usual excessive tolerances caused by the instability of wood, and helping to reduce performance failures and injuries from overexertion.
Composite materials allow for consistent and repetitive manufacturing processes that iron out acoustic differences between units, ensuring homogeneous quality between units of the same model, unprecedented in the world of wood-based acoustic instruments. Our musical instruments always attain the quality we are looking for.
The use of composite materials helps avoid over-exploitation of natural resources. We contribute to sustainable development by using composite materials rather than exotic woods, avoiding the mass felling of centuries-old trees whose noble wood is currently used by the classical instrument manufacturing industry.
