I have had singing lessons for a while now. My teacher has said on numerous occasions ‘don’t worry about your vibrato, it is fine’. I still have to work the technique don’t get me wrong, but it is there.
I can’t help but notice, naturally, other singers vibrato.
Some are very fast, it sounds like an engine, I think this sound is better to be honest, and some are more looped, like you can hear the actual waves within the vibrato pitch more clearly. Opera singers I have found tend to have this ability. To really make it sound as whole and as full as possible.
Everyone’s voice is different yes, but should all vibrato be the same? Is a quicker vibrato used for certain songs or styles? Likewise the other way round? What is the goal for vocal vibrato in a modern world where volume and large amphitheatres are (broadly speaking) no longer a problem.
