I've been thinking about vibrato and straight tone in singing. My main focus is on what we call classical techniques.
I recently started taking singing more seriously (like an amateur) and it seems that in classical singing you have people who are more trained in using more vibrato or more straight tone. Some people are trained in using both straight and vibrato, I think.
I know of one opera singer who also sings the music that Frank Sinatra sang. I hear a lot of vibrato on some notes. I find it unnecessary.
He sounds like this:
I find that singing with a more straight tone (which does include vibrato at times) to be easier for me. We also speak with a straight tone, I think.
To me vibrato feels like a natural thing but the vibrato you hear in classical singers like Jussi Björling sounds unnatural. Jussi singing:
This is the straight tone (with less vibrato):
I would say that the straighter sound feels easier although it takes much practice to do it well.
Could one say that the straighter classical tone is more natural than the classical vibrato tone?
