You get vibrato in your voice by slightly backing off the tension applied to your vocal chords. This causes them to relax slightly and begin to oscillate between two pitches quickly - creating the vibrato voice effect.
A person who sings or plays any form of music that can have vibrato, and adds a lot of vibrato to their playing to make it sound better to hide how bad they suck, because that is all they know how to do.
Woah, look at her play the violin, it sounds so good
No, she sucks. All she is is a vibrato slut.
Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
