word which means the vibration of sound in voice

[alpacinou]

Hello

What is a word which means the vibration of sound in voice when someone is singing a song? I mean when a singer goes from low-pitch to high-pitch and low-pitch again and they vibrate their voice like a bird is singing?

example: You have to sing this song with...... (noun)

You have to .......(verb) when you are singing.

I mean you can't just sing it in a normal voice you have to go up and down and vibrate....

I found "warble" but Oxford says it is humorous.

I'm not musically literate, but I wonder if "trill" is the word you're looking for.

Are you thinking of vibrato?

For a demonstration of vibrato, go to 1:08 in this video and listen for about 8 seconds. I don't think that's what you mean though. That's not someone going from low pitch to high pitch and vice versa.

I really think you need to post a video/audio clip in order for us to know what you mean.

Is that Michael Palin's picture in the video?

That's strong vibrato or, if the singer is alternating between distinct notes in the scale, trilling. The singer is using a technique that isn't normally used in the European classical tradition in which those terms originated, though, so it might be better to use its name in your own language, along with a description.
