SUMMARY
The aim of this study is to present the use of phonetics in non-linguitic researches and sciences such as music and singing. Sung Lyrics of Slovenian songs/poetry have not been investigated phonetically, taking into consideration their quality (vowel formant frequency). The word is about musical art (lyrics), paying attention to the phonetic realization based upon the Slovene language and its norm, which show excellent articulation of the sung vowels.
