Selected features of the timbre of stationary violin tones are studied and their spectral sources are sought. The sound recordings of five different tones (B3, F#4, C5, G5 and D6) played on a set of violins are used. Spontaneous word description of timbre of individual sound obtained in listening test [1] was used for the selection of words, which describe specific feature of timbre (sharp, clear, dark and narrow). The same signals were sorted and assessed according to these verbal attributes in a second listening test [2]. Signals with extreme value of an attribute were modified in frequency bands with significant correlation between their levels and verbal attribute magnitude. Sorting and assessment of modified signals was used for the recognition of a potential spectral source of a studied timbre feature. The frequency position of the main source for sharpness and narrowness is established and its pitch dependence is discussed.
