The problem with so called "singer's formant" is not only limited to the name itself. But because terms determine the content of and set a limit to the practice of definition, to tackle the problem of the name/concept of "singer's formant" is the most urgent of these problems. Although in studies on various non-operatic singing styles, no evidence of such formant was found, this phenomenon has continued to be called singer's formant, and in literature there is no sign of disapproval in this regard. The act of singing is not unique to any given musical genre. The person who sings in any genre is a singer. But, although it was found only among the Western opera singers, to decorate this phenomenon with the prefix 'singer', intentionally or unintentionally, restricts one to be a singer of only the Western opera singers. What links music with science, or to put it another way, transforms music into musicology, is the application of scientifically defined methods on every musical matter. In this regard, in this study, an efford was made to offer a scientifically appropriate name to the acoustical phenomenon that called "singer's formant" until now. It was concluded that instead of "singer's formant", "Western opera singer's formant cluster" (FCwos) must be used for the peak found in the Western opera singer's.
