Adam Neely: How does vibrato relate to rhythm?

Vibrato is that natural oscillation of pitch that singers often use when singing sustained notes - music theorist Adam Neely points out in his latest video. He gives examples like Schubert's 'Ave Maria', and Duke Ellington's 'Caravan', and how much they lose without using vibrato. YouTuber/musician also offers some advice on the approach to music - "Take music very seriously, but maybe don't take yourself so seriously as you do it", and about a career in music - "You should be passionate about what you do and you shouldn't make any decisions out of fear".
