Andrew has always been excited by the colours, textures and aromas of the violin-making tradition. Leatherwood Bespoke Rosin evolved out of this passion, offering string players a means to directly inform and shape their rosin experience. Andrew believes the relationship between client and maker is just as relevant for rosin as for instruments and bows. With many years experience as a professional performing violinist, pedagogue, researcher and manager, Andrew wishes to continue contributing to the experiences of string players through a product that enhances their playing and indulges their senses.A graduate of Sydney Conservatorium of Music (performance) and the Australian National University (string pedagogy), Andrew has received numerous awards and prizes during his school years. He has lived and studied solo performance, chamber music and baroque music period practice in Amsterdam studying with some of Europes finest teachers. He has worked as Head of Strings and Director in regional conservatoriums, and as concert master and soloist with a number of orchestras in regional Australia. While contributing to the string-playing world through Leatherwood Bespoke Rosin, Andrew founded and leads Colour City Chamber Orchestra.
As much as we rely upon rosin as a vital ingredient in sound and response enhancement, it is hard to decipher exactly how, or in what way, a generic rosin recipe enhances your sound. Some rosin brands offer no description whatsoever on their sound and response characteristics, and for those that do, the messages are often general, generic and all encompassing. More importantly, the experience of a rosin is very subjective. Two players will find their experience with one rosin vastly different because, for example, of differing types of bow, strings, bridge, instrument qualities, and even differences in their technique or playing style.
The main sound and response characteristics rosin can affect are:
Varying these characteristics in your rosin can affect brightness and projection, the amount of surface noise (the clarity of the traction), the depth / warmth or richness of sound, and the overall effectiveness of advanced techniques such as triple stopping, sautille, spiccato and sostenuto.
If you need a rosin with a stronger initial, attack, a smoother feel, a brighter sound or less surface noise, how do you go about finding one that does specifically that? Which do you buy?
Differences in playing qualities of rosin depend almost entirely upon the species of the tree, environmental and climatic conditions of where it is grown, but more so on the method of extraction from the tree and how the rosin is distilled. Rosin can be extracted in two ways. It can be ‘tapped’ from a cut in the trunk (this is called Gum Rosin), or chemically extracted from tree stump pulp using a chemical-based method (called Wood Rosin). Very generally, gum rosin tends to be more brittle and powdery, and wood rosin more tacky. Rosin can then be distilled to varying degrees resulting in the different colours from clear to dark brown / black.
Raw resin ingredients vary to a such great degree that a rosin maker has a wide choice of ingredients, all of which feel and sound different. As rosin is the interface of bow and string, the stickiness and texture of the rosin will significantly affect the vibration of the string. So when choosing a rosin, the player must consider carefully what sound and response characteristics they wish to enhance, rather than simply looking for something that might just be a welcome change from their current rosin.
For the first time in rosin history, string players can enhance their sound and response to suite their instrument, style and playing contexts.
