Get Started


Say something, I'm giving up on you. I'll be the one if you want me to. Anywhere I would have followed you. Say something I'm giving up on you. And I am feeling so small. It was over my head and nothing at all. And I can stumble and fall-- I messed up the words. We had a stumble and fall. If this happened live, we would just keep going. Yeah. But right now-- Yeah. Let's take it again. Because some of the timing wasn't perfect in some of the-- what was it? It was the beginning though. And I (SINGING) know nothing at all. Wait, wait. I think it was "head." (SINGING) I'm feeling so small. It was over my head. It was something. Our timing was off on "it was over my head." (SINGING) And then nothing at all. And then I just, I had to stop because something in the "and I will." Right? And then we went into "stumble and fall," and just had to laugh. Because we stumbled and fell. But we wouldn't do that in a gig. No. But if we did do it on a gig, you just keep going. And it almost refocuses you to hone in more with your timing. Sure. So, right? OK. Take it again real quick. [PIANO PLAYING] (SINGING) Say something, I'm giving up on you. I'm sorry-- Oh, I'm sorry. It's OK. I'm actually sorry. Now what's happening is we start to overanalyze ourselves. And we start nitpicking our mistakes. And that's sometimes why I don't like to over-rehearse. Because it should feel good and organic. But yeah, take it again. Back to the top. (SINGING) Say something, I'm giving up on you. I'm sorry that I couldn't get to you. Anywhere I would have followed you. Say something, I'm giving up on you. It's almost like you have to keep it one, two, three. One, two-- (SINGING) And I-- One, two, three. (SINGING) Can swallow my pride-- Look. I'll continue the notes. So it's almost like you have to keep a one, two, three. One, two, three. Silently in your head. Pick it up here. (SINGING) And I-- One, two, three. One, two, three. One, two, three. (SINGING) Will stumble and fall. I'm still learning to love. And I was busy saying one, two, three. I forgot where it is. (SINGING) Starting to crawl. Momentum builds up in your head. (SINGING) Say something, I'm giving up on you. I'm sorry that I couldn't get to you. Anywhere I-- Shit. Now we're just all over the place. I would-- see, what happened just now was he went for the-- (SINGING) Anywhere I would have followed-- And I went for the ending. (SINGING) Anywhere I-- And that's why it's so important to know where we're at. But we stopped and started many times within this last take. So we got a little confused. I got a little, he did it right actually. I went for the end chorus and decided to wrap it up. How do you get back up from a mistake? You laug...

Your New Voice Teacher

Christina Aguilera teaches you how to expand your range, find your voice, and master the techniques that have earned her five Grammy Awards. In her first-ever online singing class, you’ll learn warm-up exercises, breath control, vibrato, her signature growls, and hear Christina break down her biggest hits. You’ve never had vocal lessons like this before.


Students give MasterClass an average rating of 4.7 out of 5 stars.

I only sing for fun, so a lot of this was well beyond what I needed to know, but it was so interesting. I've been a fan for so long!

The observations & lessons in this course can be applied to every area of life, not just singing. Well done.

I feel the class has empowered me in many ways. I love the fact that I could learn to expand my range and understand the experiences that make Christina Aguilera who she is today. What I need right now is a personal vocal trainer that can push me and motivate me to keep learning. I really enjoyed this class!

Love her, just wish she went a bit more into technique but great overall.

I really like the drummer guy very agreeingly nod his head hard xD But, I need to learn how to laugh it off mistakes!!!!! Thank you Christina >.<


I really like it when Christina sings softly and also do like it when she keeps it simple, she has natural talent, the less she tries, the better, I would love to see her one day, completely just NOT try at all. Completely stripped back vocals, no trills, no technique. Maybe that is a lesson for everyone...just sing, be yourself, don't try!

This rehearsal is a million times more raw and emotional than the song itself. Thank you for making me cry while tryna learn singing, Christina. haha

This lesson was so organic! It reminds me of rehearsal with my band. Incredibly important to have that connection with your performance buddies. You feel their movement and they react to yours. So wonderful

What a duo... My god. She's amazing – of course – but the guy is terrific too.

Patricia D.

This song kills me! So heartbreaking, and watching them practice and sing it together is amazing.

Stefano P.

It would be nice to have a track with Christina's voice and to be able to record a duet :)

Morgan D.

I missed several of the places they said they made mistakes while practicing. Goes to show... the audience doesn't catch everything you do. We NEED to get out of our heads!! I loved this lesson... THIS is why I love Masterclass! It's really fun to just be a fly on the wall, watching these experts do their thing.

Such a raw powerful performance, brought out the emotion and the vulnerability in the human condition. SO far what I am taking away is that it is the EMOTION expressed via the voice which adds the essential element. What a privilege to see these performers warming up, I had never heard this song until today - beautiful and soulful.
