The present article focuses on the question of whether the timbre difference of two sounds with harmonic spectra, produced by natural musical instruments or the singing voice, may influence subjective assessments of the pitch of one sound in relation to the pitch of the other. The authors administered a series of perception tests to a group of professional(More)
Singing teachers sometimes characterize voice quality in terms of "forward" and "backward" placement. In view of our traditional knowledge about voice production it is hard to explain any possible acoustic or articulatory differences between the voices so "placed." The analysis of the teachers' expert opinions demonstrates that, in general, a voice placed(More)
This research describes the strategy of singers in reacting to the pitch deviation from equally tempered (ET) value in their ensemble partner's part in singing two-part a cappella music, and the ability of professional musicians to identify such deviations. Professional singers preferred to maintain the purity of melodic intervals in their own part and to(More)
Singing teachers sometimes characterize voice quality in terms of 'forward' and 'backward placement'. In view of traditional knowledge about voice production, it is hard to explain any possible acoustic or articulatory differences between the voices so 'placed'. We have synthesized a number of three-tone melodic excerpts performed by the singing voice.(More)
Fifteen professional singers sang simple vocal exercises at different pitches. The sung excerpts were recorded, and seven modified versions were created from each recording. The modifications were then played to the participant and (s)he had to assess the similarity of these stimuli to the perception of his/her own voice during the act of singing.(More)
The paradigm of Signal Detection Theory (SDT) was used to analyze the ability of professional pianists (N = 16) and string players (N = 15) to discriminate small F0 differences between consecutive musical tones, presented in pairs, with identical and with different (bright and dull) timbres. The sensitivity (d') and response bias (c) were heavily dependent(More)

This work aimed to investigate glottal adduction in the case of the singing of diatonic D major ascending scales with different dynamic shapings on vowel [a:] by 10 classically trained male singers. The parameters obtained by inverse filtering-closed quotient (CQ), normalized amplitude quotient (NAQ), and the level difference between the first two partials(More)
