Analysing Bass Clarinet Multiphonics

Together with bass clarinetist Chiara Percivati we are exploring the extended harmonic space of multiphonic fingerings. Using several timbre descriptors we obtain different visual arrangements of the multiphonics given these descriptors. One of the outputs of this ongoing process focuses on the development of a useful resource to survey the catalog and obtain useful information about the fingerings {read more].
