The process of designing a model takes many stages, a process which has evolved over the past 30 years for Tim Jansma. He studies in depth by making exact copies of many of the most beloved historic instruments, including instruments from makers such as Stradivari, the Guarneri family, Gofriller, the Amatis, Guadagnini, etc. Tim is grateful to all the musicians, collectors and dealers over the years who have graciously made these exquisite instruments available to him.
Modification is equally important in understanding proportion, balance and volume of the airspace within the belly of an instrument. When Tim designs his models, he spends months making drawings of outlines, adjusting by fractions of a millimeter here or there for the sake of performance and beauty, all the while applying his knowledge of proportion and resonance.
