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...

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.

Edward D.

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.

A fellow student

I absolutely love this lesson! It's raw, it's real. It's showing most importantly, that professionals practice! Professionals mess up! I get so bogged down by trying to be perfect all the time, when it's the imperfections that sometimes MAKE the song. :) I feel like I'm getting that fly on the wall opportunity that I think you never ever think would be possible.


take me back to 2001 when singers could actually sing. Great job, Christina

Cassandra K.

Such a beautiful song! Had me in tears at the end of the lesson. Eye contact really makes that quality difference in connection and feeling.

Duets double the fun, but mistakes are gonna happen. If, we are well rehearsed, strive to be and do our best, make the slip, pause, laugh, regroup, recover and move forward and give the audience all they deserve.

Nastasia M.

I love the little lessons and reiterations of how to move past mistakes, how to work with counterparts and find space to yourself, space with your partner, and space with your wider audience all at the same time.


I love Christina's voice. Her tips on this one were great and practical. Her masterclass is improving with every chapter
