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


So part of my process before any performance, while I'm in the vocal booth, there's a whole ritual thing that happens with my drinks. And even with interviews sometimes, I'll need my plethora, I call it, of drinks because I need my options. "Options" is a big word with me. So we have hot coffee, hot tea. I'm not a huge fan of Throat Coat. It's great for singers, I hear, not for me. I'm very tea taste picky. So we have my hot coffee, my hot tea, room temperature water, but really cold for after I'm done with a concert and straight off the stage. And during the performance, I'll go through just very quickly, just I need honey ready to go on a plate, already opened, ready-to-go Ricola throat drops. Sometimes I have my throat spray. It's always in the go-to vocal bag. So that's it. That's my weaponry of fuel to perform. So I have a system where I definitely have my side table, and I set it up on a stool. I don't care who sees it from the audience. This is my thing as a vocalist. And it's set off to the side where I literally will just use it during my performances while the audience is watching-- or in between songs, rather, not during the performances. But in between songs, as we're taking a moment and I go on to introduce maybe the next song and when the time feels right, I'll take a little swig of honey, just plain, raw honey. I have it set out on a plate with my throat drops just ready to go, unwrapped. No fiddling, fussing with the wrapper and the paper. Just boom, they're on a plate with the honey, maybe a little spoon on the side. But sometimes there's no time for that and I've just got to use my finger. And room temperature water. There's no time for sipping a hot beverage or a liquid and burning your tongue or whatever it is. You've got to go for the room temperature water. You don't want it too cold because that will tense up your throat. Although, at the end of a performance, give me the cold water. I just need something cold because you're hot. You're sweaty. You're done with the show. You don't have to necessarily have the room temperature anymore because the show's over and you can go ahead and breathe and relax and switch onto whatever other beverage you may want to decompress with. I myself am guilty of being excited for a show. You're in sound check. You're in your comfort zone of your own people behind you-- your band and your dancers-- and you're vibing. And sometimes just getting in that energy field of everybody coming together and doing material that you all love and know, it's a fun thing. There's no audience. There's no kind of pressure. And it's easy to sort of blow out your voice during a sound check because you might get so into it and you're fresh. It's the top of your day, whatever it is. But you've got to be really careful because if you overdo it in a sound check, yo...

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

Although I'm not a pro singer, I loved this masterclass for Christina's knowledge and her positive attitude. It was just a really fun class to attend!

Music is in my blood... Hence, I want to step forward in my singer career. This masterclass for sure will help me to reach an overwhelming success.

One of MasterClass' first MasterClasses offered is amazing for both singers and creative people alike. Lessons 19-23 were my most favorite lessons.

A fantastic life class... not limited to voice or music.

thank you its been useful to know the use of vocal cord warm up. the importance of posture and exercise.

Another thing I'd like to add to list of environmental things to avoid/be cautious with is DRINKING ALCOHOL: Alcohol is SO DRYING to your voice, and can dry your voice out within minutes of consuming it up to an entire day or two later, depending on how much you've consumed. Dryness will decrease your range, decrease your vocal power, the smoothness of your transitions, stifle your overall vocal endurance & stamina, and therefore decrease your confidence and vocal ability when you need it the most. Dryness of the throat/mouth is naturally likely to occur without any alcohol consumption due to pre-performance nerves before a performance, and all the water and throat drops in the world won't help you in the moment if you've been dehydrated for the past day or two. ALSO--singing while intoxicated THROWS OFF YOUR ABILITY TO ACCURATELY IDENTIFY me...all these things I've just mentioned are learned from personal experience. I don't drink alcohol until towards the end of the final set at a show, if at all. People will be wanting to buy the band shots/drinks throughout the show (especially if you're female, lol) so you really have to stay mindful and vigilant about what you're drinking and how much of it.

Why are you talking about how to perform at shows? We're not performing at shows. People who are taking this course want to learn how to sing. They don't need performance advice!


I forgot the power of warm-ups! I took voice lessons when I was in high school and it brought back a lot of the concepts. I especially like the discussion and the advice Christina gave about when you’re reaching the high notes, to look down on the note instead of trying to reach up for it. That was super helpful! I’m trying to expand my range.


I like this lesson, but as a beginner, I would truly appreciate a warm up recommendation (or few) instead of a link in the workbook to 243 vocal warm ups on Utube. Christina, you say you use a tape that you've had since you were 16. Could you kindly share it? Would love to hear you guide us through a warm up! Thank you, Holly


I'm struggling to finish this class. I love Christina, but this isn't a singing least so far. This is a class about performing after you already are recognized as having enough talent at SINGING to perform in front of people.

I love the lesson, however is there a vocal track that we can get or access to help with warming up? How do we know what vocal warm up exercise is good for our voice? How do we find one that helps improve and doesn't create bad habits or strain on our voices? I love hearing tips, but I'd love to get actual vocal warm ups, as I know for example if I go on youtube there are so many. Which one is best suited?

Andres S.

All you masterclass students be careful of your hair and makeup people. Don't be too hard on yourself when you're touring. I love all these relatable tips and tricks.

Rainy H.

Thanks for the great tips about the water temperature. I had no idea that honey was a good thing for singers to put in their throats. Thanks for the tip.

I notice in Christina's talking voice quite a bit of vocal fry which I've always heard can be damaging. I know it is for me, anyway. Christina, is this intentional or do you feel it has any negative effect on your voice? Have you ever been told to speak in a higher register instead of so much in your chest? Just curious.
