Prof Tai acquired maple specimens from four Stradivari instruments and one Guarneri. Nuclear magnetic resonance revealed that all the historical maples exhibited hemicellulose degradation of around one-third over 300 years. Hemicellulos is the most hygroscopic component, and its degradation leads to reduced moisture absorption and reduced internal damping, allowing the wood to vibrate more freely.
