Wine glasses as multiphonic instruments forced to sound like monophonic instruments

Mehr zum Buch

The study explores the acoustic properties of different singing wine glasses, focusing on two excitation methods: finger-excitation and hit-excitation. Finger-excitation produces a clear monophonic sound, similar to that of monophonic instruments, while hit-excitation results in complex multiphonic sounds. The research provides insights into the unique sound characteristics generated by these traditional instruments, enhancing the understanding of their acoustic behavior.
