ELi5: What actually causes vibrato when singing?
In: Biology
Vibrato is a style/quality of singing, and it’s something you consciously choose to do, so I don’t know that I’d phrase it as “causes vibrato”, but to add vibrato to a note being sung you simply slightly tighten and loosen your vocal chords to fluctuate the note being sung so it’s not just a constant flat note.
In the same way you would add vibrato to a violin or cello note by slightly moving your finger to shorten and lengthen the string to change the pitch a slight amount to the same effect.
