From a perspective, Paolo Cherubini emphasizes the value of dendrochronology – an objective and non-destructive method – to assess the authenticity of musical string instruments. Stringed instruments, especially those created by luthiers from northern Italy in the 17th centurye and 18e centuries, especially the Stradivari family, are among the most beloved and beloved works of art in the world. Widely regarded as superior in tonal qualities, these instruments have been the preferred choice of musicians for centuries. However, it can be difficult to verify the authenticity of these musical instruments – a simple examination of their style and design, both subject to counterfeiting, is often insufficient to confirm the manufacturers. Thus, the authenticity of certain instruments has long been contested. Here, Cherubini discusses the use of dendrochronological methods to establish the age and provenance of these valuable works of art. Dendrochronology uses the characteristic patterns of annual tree growth rings – features clearly visible on the wooden facades of stringed instruments – to determine the age of the wood used in its construction and the potential region from which it originated. Unlike carbon dating and isotope analysis, dendrochronology is the only objective, non-destructive method that can provide a date after which an instrument could have been manufactured. While the approach is useful, Cherubini stresses that it is important for musicians and art collectors to understand the limits of dendroecological authentication. The method does not give an exact date of construction but rather a date before which it was certainly not made; it may still be limited by the availability of reference chronologies of tree rings. “Dendrochronology allows objective verification of date assignments made on the basis of art history and stylistic criteria and offers a nondestructive and scientifically sound analysis technique when properly applied,” writes the author.
