ELI5: Why do we find vibrato to be pleasing?
gpt
So, it's actually really interesting—if you listen to pieces from the Baroque or Classical periods, vibrato is never used because there was more of a focus on perfect harmony. In the late classical and Romantic era of music, these rules were broken for the sake of expression. IMO, it tends to add a warmth to longer notes especially because of the fact that hearing the slight wavering of a note with vibrato is perhaps less drone-like than a perfect sine tone.
