Eight professional singers sang scales including their passaggio range on different vowels, applying two formant tuning strategies as found in (Citation) classical and (Citation) non-classical singing. Formant frequencies were measured using inverse filtering. Results revealed differences between the two strategies. For the classical formant tuning, systematic changes of formant frequencies with pitch were observed. For the highest note sung on /a/, was below the second partial and in the vicinity of the third. Similar spectrum characteristics were achieved by different and values between singers.enAtribución-NoComercial-SinDerivadas 4.0 Internacionalinfo:eu-repo/semantics/openAccessartículoformant tuningmale singersspectrumharmonics
