The Instrument Maker Who Sources Wood from Fallen Trees Only

Luthier William Cumpiano, based in Northampton, Massachusetts, builds guitars exclusively from wood salvaged from naturally fallen trees. His commitment began after witnessing the environmental cost of tropical timber harvesting and hardened into a practice producing over five hundred instruments, each made from wood traceable to a specific fallen tree.

The acoustic argument for salvaged wood is compelling. A tree that has fallen naturally and seasoned on the forest floor for years offers tonewoods of exceptional stability. The slow drying produces wood with lower residual stress than kiln-dried timber, resulting in tops and backs that vibrate more freely and produce warmer, more open sound.

Sourcing requires a network of foresters and arborists who notify Cumpiano when significant trees come down. A fallen Sitka spruce in Oregon or a windthrown walnut in Pennsylvania each represents potential instrument wood, but only if harvested promptly before decay organisms compromise structural integrity.

Salvaged timber earns its reputation through how it is converted and dried. Billets are quartersawn so the growth rings run perpendicular to the face and the medullary rays show as silk, the orientation that gives the greatest stiffness across the grain for the least weight. Air drying follows the old rule of roughly a year per inch of thickness, and the wood is then held in the shop at about forty-five per cent relative humidity until it settles near six to eight per cent moisture content, the point at which plates can safely be joined.

Cumpiano's instruments challenge the convention that great guitars require exotic tropical hardwoods like Brazilian rosewood. His work with domestic species including black cherry, red maple, and American walnut demonstrates that tonal excellence depends more on the individual piece of wood and the maker's skill than on the species name.

Sourcing is now a legal question as well as an ethical one. Every species in the genus Dalbergia, which covers the rosewoods, was placed on Appendix II of CITES in January 2017, and Brazilian rosewood, Dalbergia nigra, has been on Appendix I since 1992. A 2019 amendment exempted finished musical instruments from most permit requirements for non-commercial travel, but a vintage guitar with a Brazilian rosewood back still needs pre-Convention documentation to cross a border, and instruments have been seized for want of it.

The ethical dimension extends beyond sustainability. By proving exceptional instruments can be made from locally sourced, naturally fallen wood, Cumpiano undermines market pressure driving illegal logging of endangered species. Each guitar from a windthrown tree is a quiet argument against exploitation of tropical forests.

Cumpiano is also the co-author, with Jonathan Natelson, of Guitarmaking: Tradition and Technology, first published in 1987 and still the standard workshop manual in English. It explains why his influence exceeds his output: a builder who never handles one of his instruments may nonetheless be working from his jigs, his neck joint and his sequence of operations. That the book is still open on bench tops nearly forty years after publication is the practical measure of it.

If commissioning a guitar, ask your luthier about wood sourcing practices. Consider specifying sustainably sourced or salvaged tonewoods, and accept the longer lead times ethical sourcing may require. The instrument will be no less beautiful for the consciousness behind its materials. Learn more at https://www.cfrguitar.com
