This video helped me figure out how to sing overtones literally in a couple minutes. The “whisper rollercoaster” prompt for getting a feeling for tongue placement was genius! Thanks Stuart!
Wow, this is the most awesome, comprehensive and informative video that I've found on this topic. Listening to You sing these dual tones, is so amazing!! They didn't teach this technique in classical voice training, or in opera workshop or in any of the music classes and training that I've had over the years. You make it look so easy. I'm trying really hard not to be jealous (lol). Thank you for sharing the wind sound blowing exercise, because that helped me understand my tongue placement and how to move the pitch of the harmonic tone - and thanks for explaining that it's best to sustain the base note for as long as possible to have more time to harmonize. I could get the polyphonic whistle tones after a couple of attempts! I'm going to practice to make sure that my harmonic frequency sounds like a whistle sound - rather than like a Didgeridoo. Thank you for sharing this fantastic video!
I am coming back to this video again and I am really impressed by one of the best overtone singing tutorials in the world wide web. Thanks Stuart. Greetings, yours Jens
I was shocked. Ive spent a lot of time trying to figure this out and i was so skeptical at the beginning, but when you taught how to change the pitch of the overtone and i did it and it WORKED?!?!? And i could hear it???? I was floored. Great video.
Wow. I've learned the little I know about overtone singing by myself. I used to change the pitch of each harmonic by moving the lips, but I didn't know that doing it with the tongue is the right way, thanks a lot for the lesson and excercises, greetings from Honduras.
Thank you very much for sharing your skills. I can use your vocal training to help me with my movement trouble. I have a rare neurological condition and I am learning how to control my vocal cords and breathing. I use to practice meditation with breathing and singing helps my breathing skills. I have a natural ability to sing well too because of my mom. She was a musical genius. Sadly drug addiction caused her to lose everything and she wasn't able to achieve her dream to be a singer. Instead she passed on her ability to my brother and I. We use to sing together for fun and we even had a band and I was a DJ for years for small events. Mom passed away from cancer in 2016. I am autistic and I am trying to figure out how to get my artwork noticed. I have a feeling art is over done and I might be stuck. 🤷🏻♂️ I am okay with it. I've never been able to work because of my handicappies. I thought practicing my singing again can take my mind off my anxiety so here I am. ❤️ You are amazing.
Oh my gosh, I am loving this video! I found three other people teaching overtone singing, but wasn't able to get the overtones after a couple months' practice (once I thought I heard it a tiny bit)...then I found this video last night and I got it! So happy and excited!😁
Omg ive watched a dozen videos and have been trying soooo hard and watching this video - I JUST GOT IT! ITS SO WEIRD! What a great breakdown! Thank you!!!!
I really wanted to learn to overtone sing and figured it out on my 50 mile Commute home from work last night lol now to master controlling it like you and being able to move the pitch!
THANK YOU sooo much for sharing !!! Well summarized, clear and precise :-) LOVE IT - although I'm 3 years late to find it … it's my christmas present :-) Blessings, love & light
You remind me of Brian Wilson, which makes you a musical genius by default:) I'm still not 100% sure where your tongue is placed during all of this, and how much it's moving around to get the different overtones. Thanks for this VERY helpful tutorial. I'm an old musician, trying to learn Hu Mai and overtone singing. Never too late.
@@TheStuartHinds Thank you. I'll watch all of them. I'm on the verge, but just struggling with tongue placement. Wish I could get a small camera inside the mouth of someone doing this😆. I AM starting to hear faint overtones every so often.
Since I haven't seen anyone else mention it; was the melody you demonstrated the english horn solo from Dvorak's "New World Symphony"? It hit me out of nowhere as an oboe player! Also, thanks for this wonderful video, I have to learn overtone singing for a class of mine and this is a great start!
A very good vid, thank you. One crucial part I am missing is the 'visualizing what the tongue is doing' part around 4 min's. Since I can make the whooshing sound several ways I don't know what you mean. What should the tongue be doing?
Yes, you have to feel it. To oversimplify, raise the mid-back of the tongue for higher overtones and lower it for lower pitches. That kind of movement is used to make the 'roller coaster' effect.
Actually, whistling uses similar vocal tract positions to overtone singing. The difference is that in whistling there is no vocal fold vibration. Ha! That is the topic of one of my upcoming Overtone Minute videos
Thanks for the helpful tips! I definitely have the overtones working but am having trouble getting them louder relative to the fundamental note. Is that something that just gets better with practice or is there something I might try differently? This is just so cool, thanks again.
You have it now. Just feel the vibrations in the head, not the throat, and focus your mind on the sound, not the effort. Keep going and let me know if you need more help.
just focus on feeling the vibrations in the soft palate area, not the throat, make sure your breath support is strong, and remember that I have been doing it for overo 20 years. @@joek292
@@TheStuartHinds thanks, I seem to have trouble with feeling anything in the soft palate but did get a bit more volume thinking of aiming the vibration in the harder palate above the back of my top teeth where you would put your tongue for a ‘T’ sound
Thank you so much for sharing your wisdom ! This is very helpful ! I have one question what happens if you don't keep the energy or the vibration only in the soft palette, what if it's strongly vibrating in the throat ? thank you so much i love this channel and all the excercises ! much love !
Of course, the vocal folds in the throat are the source vibrations for a vocal sound, but the magic happens higher in the vocal tract. In general, overtones are brought out more strongly when the soft palate is vibrating strongly. Keep going!
@@TheStuartHinds Thank you so much! I was asking because I practiced overtone chanting last weekend and the vibrations get very strong, so I feel them in my whole chest area vibrating up to my head and sometimes it's not the most comfortable feeling i was wondering if that's a 'good' thing you know? I'm also still figuring out how to relax while doing the deep tones, chants, maybe you have some suggestions. with love, Janine
@@janineninger13 yes, discomfort while singing is a sign that something is not right. Often, beginning singers make excessive and extraneous efforts trying to bring out overtones. Remember that overtones are an intrinsic part of the sound, not something you are adding; the overtones come out with proper positioning, not greater effort - forcing never helps, it just makes you fatigued. If you post a short video of yourself singing I will view it and tell you what I observe. Use the "ng ~ ee" exercise from the video.
Thanks for asking. The basic technique is given in this video. Focus on keeping the energy of your singing in the soft palate area of the vocal tract. If you are having difficulty, make a short video and I'll help you.
Thanks, that was helpful. A different question: are you reading the text? If so how did you organise that. I'd like to know because it seems very helpful when doing a video. Thanks.
Don't worry and don't force it. Make sure your breath support is strong and focus your mind on vibration in the soft palate area. Check out my Overtone Minute videos, too. Thanks!!!
I really love the way you teach. Do yoy accept students? I am serious. I have fallen in love with this art very recently and would be great to find someone who can help with practicing it.
The best way to improve is to practice MUSIC and improvise a lot. My book MAKING MUSIC WITH OVERTONE SINGING has songs, lessons, and exercises for overtone singing that will give you plenty to work on (definitely get the recordings too). After that, I will help you if needed. www.stuarthinds.com/store/ Also, check out my #shorts from the last few months. Let me know how it goes.
@@TheStuartHinds can you put some review of your books? My problem is I am not sure one can learn this from a book. Even from these videos I have not been able to reproduce what you do exactly. Can't see how the tongue should move.
Also I have no background in music so I have no idea how to work on "fundamental" "pitch" "harmony" because I don't know what it means. Please help still interested as before.
@@mrh4742 yes, having musical experience certainly helps, but is not necessary. Just think of the vowel and the tongue will be in position for the highest overtones. When doing the exercises in the video, you should hear a difference between the "ng" and the vowel. Also make sure the sound is bright, not throaty, feeling the vibration in the soft palate area.
@@mrh4742 Don't eworry about the lingo for now. Just mimic what I'm doing in the video. If it just isn't working for you, post a short video of you doing the 3 exercises and I'll watch it to see what might be going wrong. Thanks for your comments!
Thanks for this amazing tutorial! In your method, does the tip of the tongue actually touch the roof of the mouth? Or is it just sort of facing upwards but not in contact with the palate?
Thanks! For this /ng/ exercise, let the back of the tongue touch the roof of the mouth to demonstrate the location of the soft palate where you should focus the vibratory energy of your singing. Of course, the tongue drops back when producing overtones. Keep going!
