Leatherwood Bespoke Rosin is proud to celebrate a decade of craftsmanship and innovation with the launch of our 10th anniversary special edition rosin, "The Golden Ratio."
This special edition reflects our enduring commitment to harmony, precision, and artistry—qualities that the golden ratio has long symbolised in classical music and violin making. Just as master luthiers and composers have embraced this divine proportion to create masterpieces, we too have woven this mathematical elegance into our bespoke range. Our "Golden Ratio" rosin features a unique 61.8% Supple recipe, further enhanced to capture the perfect balance of grip, texture, richness, and tonal clarity. This recipe intensifies rich, deep, bold, and warm sound colours, while maintaining strong focus and soloistic qualities.
We have chosen an elegant and colourful 'Cherry' timber for the casing, with a rich burgundy Australian leather wrap, embossed in gold with the Golden Ratio symbol. These luxury materials are sourced from Australian suppliers and hand made in our workshop.
For years, we have explored the bespoke range spectrum from 100% Supple through to 100% Crisp in search of a truly balanced recipe. The Golden Ratio asks a simple question: could this be the perfect rosin? More than a formulation, it is a tribute to timeless proportion and the pursuit of musical perfection.
"In modern playing there can be a tendency to favour power, clarity and volume, which sometimes comes at the expense of depth and colour.
In exploring our bespoke range, we were very curious to hear the sound of 61.8% Supple - The Golden Ratio - and found it to be robust, rich and colourful in sound. We wanted to intensify these characteristics for a sound that was more profound, as bold as can be, and allows the full colour range of the instrument to sing forth.
We found an ingredient balance that allows these qualities to be central to sound, while still maintaining soloistic qualities, good projection and strong core to the sound."
- From Andrew Baker, Director and Founder.
The Golden Ratio (1 : 1.618) is a proportion that recurs throughout nature, art, architecture, and design, long associated with a quiet sense of balance and beauty. When a whole relates to its larger part in the same way the larger part relates to the smaller, this harmonious relationship emerges—one that the human eye and ear seem to recognise instinctively. Across centuries, artists and makers have drawn upon this proportion, consciously or intuitively, to shape works that feel naturally complete and aesthetically satisfying.
In classical music, the golden ratio often reveals itself in the architecture of a composition. Climactic moments, transitions, and thematic developments frequently occur at points that closely correspond to this proportion of the work’s total duration. The result is a musical journey in which tension, movement, and release unfold with an organic inevitability, lending the listener a deep sense of coherence and emotional poise.
In violin making, this same proportion can be discerned in the instrument’s form and internal geometry. The relationships between body length, bouts, stop length, f-hole placement, and bridge position in many fine historical instruments align strikingly with these principles. Such proportions contribute not only to visual grace but also to acoustic refinement, guiding the way the instrument vibrates, resonates, and projects sound.
In both sound and form, the golden ratio serves as an unseen framework for harmony, beauty, and balance—the qualities at the heart of great music and masterful instruments.
Leatherwood’s ‘Golden Ratio’ rosin has truly impressed me with its remarkable balance of warmth and clarity. It retains and enhances the complexity of tone on my violin, whilst also delivering a crisp and articulate response. The result is a sound that projects with richness and strength, yet retains brilliance and focus. Thank you Leatherwood Rosin for producing a fine, soloistic rosin which I am extremely happy to use!
Rosin is to a performer what tires are to a race car driver — an essential key to great performance. I have been a long-time user of Leatherwood rosin, and I am truly impressed by their 10th anniversary release, the Golden Ratio. It gives my playing both power and a wide range of tonal colors, allowing strength and nuance to coexist effortlessly. This is truly a product that lives up to its name.
Especially when your instrument has been given a very good tonal setup, the difference between various rosins becomes particularly striking. The bow can be guided more relaxed and with greater precision, and the range of expression is significantly expanded as a result. The very high overtones produced by this high-level rosin act as carrier waves and create a completely different quality of sound projection. This allows you to fill even very large concert halls with your sound.
