Christina Aguilera
Teaches Singing
Christina teaches you her unique vocal techniques in over 3.5 hours of voice lessons and exercises.


I don't like to get too caught up on diction and enunciation, and all of those things. Because, then, you're getting into the area of kind of over-critiquing yourself in a way. Whenever I'm all about feeling-- I could use fighter, fighta, as a reference. You know, would I sit here and say, I'm a fighter, or thanks for making me a fighta? No, I'm not going to say it like that. But when you're in the mode of singing, you know, you take on a different shape, and a different form. That's its own sort of a feeling. That's a beauty of singing, because you use that to sort of escape, and become maybe somebody that you normally wouldn't have an easy time being in front of other people. Maybe there's an inside part of you that isn't secure. And that's the beauty of music and singing. It's because you can express yourself in ways that you normally couldn't in maybe everyday life, or in a conversation. You know, that's why song is so powerful and moving. For me, placement of, you know, oh, where does my tongue go, or how should I phrase this according to specifics, like, that's just not my style. I prefer to sort of be more loose with it. And in reference to, you know, Fighter, when I sing, I will go, (SINGING) thanks for making me a fighta. You know, and that's a feeling and that's an emotion. But if I changed it, and I was like, (SINGING) thanks for making me a fighter. Like, that just sounds kind of weird to me. And that's not natural. Off the top of my head, from recently working with Resa, I think she's kind of a good example of sometimes whenever you don't want to over-enunciate in the case of the fact that she wanted to sort of rock out a little bit, and sing Fighter. And Fighter is all about an attitude. She was very enunciated, and you can tell she's had some former training in making sure she's fluid, which is great. I mean, those are things that will come in handy when you're singing a variety of different songs. But in the case of Fighter, she was starting the song with-- you know, the first two words are, "Well, I," and it's not a two thing. You know, the way I sing it on record, (SINGING) Well-I. You know, it's kind of like a throw it out there kind of thing. And she was going, (SINGING) Well I, well I. And she was I-- you know, her pronunciation of that was sort of more an, (SINGING) Well I. You know, it was more of that. And we got her to the stage of coming back and putting more of a stylistic approach on it, throwing it away and having an aggression about it. (SINGING) Well-I. Like, I'm going to dive into this story, and I'm going to tell you. You know, it doesn't have to be so proper, I guess, per se, whenever you're trying to give off a certain energy, or a feeling in a song. There are points of reference within Fighter. When you're saying things in a repetitive line that way, and you're using multiple words to express ...

Love Christina's closing statement...I hope that she continues to learn the codified terms to communicate more detailed specifics to musicians. She is gifted!

My favorite teacher, and there are so many good ones. I am overjoyed at this course, and hope she does another one soon!!!

This Masterclass right here made me fall in complete love and respect for Christina Aguilera. She is such a powerhouse singer and her voice is pitch perfect and crystal. I learned a lot. Anyone who is interested in perfecting their voice should watch this. Anyone interested in singing should watch this. Definitely one of my most favorite Masterclasses thus far.

Focus more on actual singing and techniques and less on talking about herself.

Anyone find the cuts for each topic within the lesson with that damn music really intruding? Like jaysus, happens every 3/4 minutes. Enjoying the actual content tho

Thinking along the lines of playing a character, what are your thoughts on creating an alternate personality or stage personality for performance - like Sasha Fierce for Beyonce? And any tips for coming up with such a character for yourself?

Cara B.

It was really good and I think it will help later in life :). She is such a good teacher.


I have to say...the way the camera moves to the left and then that man appears behind her is REALLY creepy and VERY distracting. If it only happened once, then fine. But it happens over and over again! It's filmed this way in multiple episodes too. Very annoying to say the least.

How does diction serve the character in the story of your song? That is the question I took away from this lesson. There are a hundred different interpretations of correct diction, and it really comes down to what fits the song you are singing the best. Which, in turn, goes back to Christina's main point she hammers throughout the entirety of this course... SINGING IS ABOUT FEELING! I definitely will not just take a song and sing it anymore. I will always ask myself this question first. Because if you can understand the character in the song (I mean, REALLY get in their head), you can sing it with feeling and passion, and when you do that, your performance is drastically improved!

The generosity of your spirit is greater than anyone could imagine. You are very talented as a performer, teacher and a coach!

The most terrible thing I found is when I was giving my feedback, progress bar blocked submit button.

Terrific! She has really shown her range over these last few lessons. I'm very impressed. She mentioned Eartha Kitt. You might also look at Peggy Lee, especially when she sings "Is That All There Is?"
