Concerto is Leatherwood’s super-premium rosin, developed for soloists who require exceptional projection, clarity and power. Created for demanding concert performances and international competitions, it delivers a focused sound with outstanding articulation, while producing minimal dust and maintaining consistent performance throughout extended playing.
Developed after years of research and refinement, the Concerto formula is designed to meet the highest expectations of professional string players. It provides an immediate, confident grip on the string, allowing it to vibrate freely from the very start of each bow stroke.
The result is a powerful yet refined sound with excellent projection, rich tonal warmth and impressive sound stability, even during long performances.
