12 Notes Explained in 15 minutes! 

The world doesn't deserve this guy. He is just such a nice dude, brilliant musician, and now he's like the best guitar tutor on the web to boot. Not to mention he does it for free...

Kiko, I have been playing for over 30 years and you are the best teacher I have ever seen. Thanks

I finally know where the circle of 5ths come from. Mind blowing.

I think some people dont really appreciate how awesome is having basically free music/guitar lessons from a great guitarrist such as Kiko on the internet. You channel is awesome kiko!

Great video, Kiko! Interesting about the first 7 notes making the Lydian scale. Running the fifths like that always reminded me of a Steve Vai sound, and now I know why. Thanks!

I kind of turned Bitter.. when my career didn't go as planned...to the point of dissing other musicians that got high profiled gigs..but when Kiko got the gig with Megadeth..I was Soo Happy for him...He really deserves all his success... and this is just the beginning... Congrats 👏

Kiko is a very capable teacher. I like how he refers to the natural relationships between notes (harmonics, the acoustic scale). Music theory is fascinating. People should understand that music theory is descriptive, not prescriptive.

When I first saw you with Angra for your very first gig in France (yeah I was there, lucky me😇) I already knew that you were a true guitar virtuoso.... And now with all these videos you share with us I know you are also a real great teacher ! Thank you so much for being what you are, bless you 🙏🏻🙏🏻🙏🏻 (can't wait for next episodes lol)

Thanks, of course we like them, please keep them coming.

I’m going to have to watch that a few more times. This is so great! I love these kind of interconnected music theory concepts!

Love you Kiko! You’ve become one of my favorite guitarists ever

Love how you relate them to physics, it's more of an eye-opener, keep them coming please!

Imagine if all 80's and 90's instructional videos were as well made as this. Wow!

That’s the kind of video I love. Explaining things, not just assuming everyone knows the foundations of whatever the video is about

This is the video where it "clicked" for me and I finally started to understand music theory and how things are connected. I used this video as a jumping off point to really go deeper into music theory and I have improved as a guitarist so much, it's crazy. Thank you so much Kiko, you have influenced me as a guitarist more than you could ever know

I am a bassist and i sat from curiosity....5 mins later i subscribed....Bravo !!

I love your non-technical approach to a technical topic.

Really like this series! -- you have a way of explaining and connecting things in a manner that really clicks for me. Thanks much...and please keep these music theory vids coming!

Thanks Kiko for making sense of the circle of 5ths for me. I would definitely like to see more theory videos.

I'm loving these music theory videos :D So much good information in them

The first 3 three minutes alone of explaining the intervals are pure gold

Very humble guitarist. Best regards from Indonesia country 🇮🇩

One of the things I dig about Mr. Loureiro's videos is how clearly joyful he is about music, and practicing, and performing. It's a lot of fun to get to share in his enjoyment of music.

When trying to understand music theory I found myself watching a beginners piano lesson (which actually really helped explain bog-standard music theory, because it's easier to visualise on a piano keyboard). This video has made that basic information so much clearer for me when trying to apply it to the guitar! I've watched so many videos that have just confused me even more, but after this I honestly think it's (finally) bridged that gap in my understanding. Excellent stuff as always! Kiko is an absolute legend

Kiko . Thank you for taking the time to make your videos and for giving so much back to your fans we are lucky! ! You sit are a guitar madman and an inspiration Took my son to his first metal concert to see Megadeth in Indianapolis a couple months ago and you have made a new tan out of him . I already was . You guys Rocked us out ! Thanks again for giving us these videos and being such a seemingly humble and thankful good natured person . A true professional

This is the best video ive seen in my life related to this and believe me, ive seen a lot. It's a must to thank for your content

Best teacher ever! Nobody, I have seen NOBODY before, explaining or concluding out these way about the Circle of Fifths.. This way, you can really make sense of it...not only for scales or sharps and flats....but to tell out the harmonic series, and relate the chromatic scale, the penta scale....or the Lydian "Joe Satriani" scale... I wish I could download this video, it' a real true compliation of Theory.. Love your video about CAGED from the Guitar Evolution Course.. You are the best..thank you KIKO!!

Thank you SO much Kiko! I always knew where the 5th and the 3rds "came from", the harmonics, but to get the remaining notes I thought someone came up with the equal-temperament formula- the 12th root of 2. But now I understand they all came from that 2nd harmonic, just continuing the series. How cool it is to learn something new after all these years! I also love how you just kept going with, "And then you get this, and then if you go here..., etc." I can tell you love this stuff as much as I do!

TOOO COOL!! You just opened new doors for me after 40+ yrs of playing without lessons with a teacher. 👍👍. Thanx

The only rock star who cares about teaching something to his audience. I applaude you Kiko

One of the most down to earth, helpful and kindest guitarist I’ve ever seen! So wonderfully explained!❤️

Obrigado Kiko! Coming from a non-musical theory background as a self-taught guitar player, to me visualization is everything in order to understand what I’m playing instinctively. I work by way of shapes, shortcuts and patterns but I’m working hard to decypher the map I have in my head. This really helps!

As I’m mid watching the start of the video I must say I haven’t been sending comments of coolness lately because I’m taking your guitar stuff very seriously and it’s literally improving my playing- from last videos, I thank you lots! Now I’ll be getting back to this one and yet again learning in a good way! :)

Thank you very much for the great lesson. Please keep them coming. They are very appreciated.

iDol kiks, you are the best guitar teacher in the whole world..God Blesses you Boss!🙏

Amazing video! Very interesting! Love the theory. I don't get it all but I can watch the videos over a time or two and maybe I will.

I'm crying crying right now, Thank you so much !!!

Kiko is Truly an inspiring and a best Gift for our guitar players ❤️❤️ Gorgeous guitar 🎸 Awesome personality ❤️

I would like more videos of theory. The way you explain things make them more easier to learn. See you in Rockville Festival in Orlando on May 20.

Where was this kind of content when i was still a teenager? Learning so much from this guy great stuff

Único canal que eu já dou o like antes mesmo de assistir e nunca me arrependo.

I believe it is very important to appreciate and give credit to our fellow travelers that are doing something good. Kiko, you are simply the best guitar ambassador we could hope for. You have a very humble and easy going persona which is engaging - and special - due to your high profile and success. Of course you are a very accomplished player but also a musician's musician. Thank you for sharing your knowledge and being an example to others.

How lucky we are that you take the time do to this for us. Thank you thank you thank you.

Thanks, after 30 years of playing, I’m finally learning guitar theory. I’m a trumpet player so reading notation is a head start. I liked how you explain the 5th especially, easy.

Kiko,You know What?You Are A Great Teacher With simplicity,With A Lot Of Knowledge About theories, You're One Of My Inspirator,And Guitar Hero,Beside John petrucci,Dave Mustaine,James Hetfield, Matt Tuck, I Admit You As A Teacher, And Learned A Lot Of Things From You, I Wanna Be A Successful Guitarist Like You One Day, Lots Of Love From India ❤️

O que Kiko é um ótimo educador. Excelente aula!

WOW!! Kiko in 15 minutes you have taught and I mean explained in a way I understand!!! Thank you soo much!!

Finally I understood. Now it’s much easier to learn. Thx!

Wow super helpful!!! Thank you!!!

You expose the concepts in a really effective way! Maestro in the real sense of the word . Thanks!

This is the best, most clear description of circle of fifths I have heard. Thanks so much!

Science meets theory meets art. Always craving more!

Thanks Kiko! This is a great and easy to understand way of explaining something that's often a challenge to students.

Thanks Kiko, really is the first time i understand this, you make it soo easy to comprehend.......... and music, vivbation & light is how the universe its made !!!! tkns again

Really like your series about theory. It is delivered from a dofferent, much easier perspective. Thank you. I’ll be watching that video few times at least while learning.

I'm a Brazilian guy, I just know the very basic about music. I can only play the basic chords, some pop songs and stuff, and improvise some pentatonics and simple solos, but I love whatching these kind of videos. I learned to play by myself, I can learn some songs by ears, and I know that theory helps a lot. These videos help me not only with music theory but also with my English listening. Keep on doing this, Kiko! Big fan here from the countryside of Bahia (Jacobina-Ba).

Esse vídeo foi perfeito pra mim, estou num nível bem básico de conhecimento sobre teoria, e essas explicações me ajudaram a conectar melhor uma coisa a outra.

This might just have been the best music theory video I've EVER seen. Thank you Kiko, I would be really grateful if you did more of these, since I'm really keen of learning more. You're awesome!

I’m going to watch, study and practice with this video for hours.. everyday. Thank you Kiko aka Tesoro 😂

Love the different perspective Kiko. Been learning theory for 2 years and that first statement the note E contains all the notes of its harmonic sequence blew my mind but its soooo true. Great work thanks

I’m loving rekindling my understanding of music theory after many years of “just playing”, and it’s really opening my eyes to the art of the possible. Your theory videos are some of the most practical I’ve seen, thank you, would love to see more of them 😎🤘

Yes! This is great 😃 I'm watching all your lessons. Thanks a lot for sharing!🎉

👍That was interesting! The harmonics and the circle of fifths. Now I understand! Thanks for sharing!

Wonderful! Can't wait to learn about 3rds!

You leveled up my guitar playing immensly! Thank you /m/

Keep these music theory videos up! I've been playing guitar off and on for 15 years, but never jumped into music theory.

Thabk you so much for sharing music theory concepts! you explain in simple terms and easy to understand

I think the guitar must be one of the few things in the universe that can be picked up, used, made to sound, made to mesmerise...without actually having a knowledge of the discipline that governs its sound....just a reflection. I think music theory is fascinating, but mainly and simply a structure, a framework....that can be explored and seen from different angles. Thanks for the video bro. Yes this stuff is interesting!

KIKO MUSIC-MASTER!!!

I might be thinking.. this is too amazing to be true! A free lesson, from you, like this one is top top top Obrigado Kiko!!

I can't believe I get to learn this for free. Thanks so much, Kiko.

tritone...it sounds like Hegel's dialectic and very interesting. I love it.

Amazing stuff Kiko. Super clear explanation, thanks a lot

Keep them coming Kiko, I always have to play something on guitar every time you post a new video 🎸

Mind blown.. thanks kiko!

Fantastic Kiko, please keep doing this kind of videos

Thanks so much for these lessons! I never heard anyone teach the way you do. You make it very easy to understand very difficult concepts.

Thanks Kiko, I appreciate the time you take to give your fans/subscribers some theory, which always makes me extra knowledgeable. 👍

Great lesson, loved it all. Thank you Mr. Loureiro

Thank you so much for sharing such simple yet comprehensive understanding directly into valuable practice. I can't wait to afford your courses and academy. You are truly a legend in music let alone metal.

i play jazz, I know theory and still I learned a new way of looking at things:)..Thanks Kiko

Great lesson. Kiko is awesome!

Kikooo..genio!!!..se entendio perfecto man!!!...segui con estos videos estan buenisimos!..abrazo desde Argentina!

I'm still a learning, aspiring-to-be-mediocre guitar player. This short video cut through a few things I've had trouble getting my head around, and brought some important pieces together. Thanks so much and keep it up please! And I'll see you in Sioux Falls at the end of April! 🤘

thank you kiko. you are great. just keep doing this videos. 🔥😃

Great video Kiko, amazing subject, very good edith, I personallyt didn't have any music fundamental and you make it so simple I'm now diggin it! Big love from Chubut Argentina!

Primera vez que veo interesante la teoría musical👍

You are really helping me start to make sense of this. Thank you!

Amazing video Kiko! Understood a lot thank you!! And the XFiles music haha very funny.

Thanks so much for taking the time to educate us!🙌🙌

Great advice Kiko awesome for progressions✌️🤘🇦🇺

Yeah, we like videos like this. Very good info here! It started to get kinda complicated, but I was able to understand most of it. I like it when you explain it, then demonstrate it on the guitar. You are a great teacher! Thanks for the video, I hope you do more lessons like this one.

thank you for this 🙏🙏🙏🙏

One of the best music lessons I ever saw in my life! Easy going and pratical! Valeu Kiko!

Thank you for this video Kiko, it helped me a LOT. I am one who fears theory and now I'm not so intimidated.

Love this stuff Kiko! I don’t know anything about music theory and always thought I didn’t need it but I’m starting to believe that not knowing how things work is holding me back on improving or moving forward playing guitar. Thank you for this video! It’s a little over my head but still informative.

Interesting. Thanks for the explanation.

This is just awesome. Learning what I've never learned from the lead guitar of my favorite band. 😎

Kiko, your lessons are amazing! The way you teach really makes you *understand* what you're actually learning

Woah! Mindblown! Thank you so much
