Two Simple Shapes UNLOCK the Pentatonic Scale EVERYWHERE - and make it MORE musical!

Use two simple geometric shapes to instantly find the major and minor pentatonic scales anywhere on the fretboard. In this video, you'll also learn how to make pentatonic scales sound like music rather than scales, how to instantly turn them into blues and hexatonic scales, and how to fluently move within these scales up, down, and across the fretboard. This video is jam-packed with useful insights. It really is the ONLY pentatonic scale lesson you will EVER need.

I have watched this multiple times. I can’t tell you how valuable this is. A perfect explanation that makes sense and opens up endless possibilities. Extremely well presented in voice, visuals and pacing. As good as it gets. Thank you very much.

[@fretscience]

Much appreciated, Tom! I’m so glad you’re finding it helpful 🎸🧪🤘

[@BluegrassPOV]

EXACTLY! I love this channel!

[@Chris_Nouvelli]

Within the space of four videos, Fret Science has quickly won my ‘Favourite New Channel’ accolade. What truly brilliant resources you’ve provided. I’ll certainly be going to buy the PDFs. Many thanks.

[@fretscience]

Thanks, Chris…your kind words are greatly appreciated! 🎸🧪🤘

[@chinapaulo]

I’ve been playing the guitar for 30 years, and this lesson has completely changed how I understand the geometry of the fretboard. Absolute breakthrough moment. The scale forms we memorize are “true”, but they’re derived from the underlying pattern!

[@chinapaulo]

It’s already changed how I approach improvisation. Instead of thinking, which form do I need to use?, I just find the first root that I want to center the melody around and use the stack+rectangle to move around it. It’s so simple, and it ends up sounding so much better. This lesson was a massively important moment in my musical journey.

[@fretscience]

This is fantastic to hear, and it exactly mirrors how I felt when it clicked for me. Cheers! 🎸🧪🤘

[@Trutzy]

I can't believe it! It's like finding the holy grail of guitar instructional videos. This is the video I was hoping for when I clicked on the last 50,000 KZbin guitar videos! I just bought the cheat sheet pack and now I'm ready to stop "searching" and start "working". Thank you Keith!

[@fretscience]

Thanks for your kind words! I have a feeling you’ll like some of my other videos too 🤣🎸🧪🤘

[@keithlamontdavis8047]

This is how I've viewed the fretboard for decades. I can't believe this isn't how it's always taught. People love to over complicate things.

[@fretscience]

I suspect most teachers pass on the knowledge in the same way they learned it, which is why, for example, the CAGED methodology hasn’t been significantly updated in 50 years. Cheers! 🎸🧪🤘

[@skippy6086]

@@fretscience- except CAGED is great at enabling mentally mapping scale patterns to chord voicings and arpeggios

[@fretscience]

@@skippy6086 you might want to check out the next video in the series. CAGED is great, but it’s not usually taught effectively…I’m trying to change that

[@justindensonvibes]

It was easier for me to just play all the patterns over and over again all over the neck until it worked itself out. To a jam track, of course.

[@LittleLunaFox]

Holy crap…someone give this man a medal or some kind of award! This is gold! Something you maybe want to point out in your videos that you kind of skip over is how your shifting up and down takes advantage of the fact that the top and bottom strings are both E strings, and will therefore always have the same “pattern” on them and that is how you can “fill in” the notes as you shift a pattern up or down. That took me a second to figure out.

[@fretscience]

Thanks! That’s definitely a good point for 6-string guitar. I’m always thinking of how the method applies to 4-, 5-, and 6-string bass and 7- and 8-string guitars, where that doesn’t work, but it’s definitely something most of us can use 🎸🧪🤘

[@fenderjazzbrian]

@@fretscience Yes, this works great with the 4-string bass as there is no warp. There was a video floating around that did something like this, but with 3 shapes. It was most useful in moving up and down the neck, but not as helpul as this approach using 2 shapes and moving vertically, and as a deeper learning tool as used with the companion videos.

[@jjolson2000]

This is so good. After 30 years of playing by ear in cover bands, I’m finally trying to actually learn the fretboard the way I should have years ago. This logical framework is brilliant, and so much better than rote memorization. The animations are excellent. I purchased every PDF you offer - keep this great stuff coming!

[@fretscience]

Thank you! There’s more in the works…I’m doing this alongside a non-music full time job, so it’s a bit slower than I’d like 🎸🧪🤘

[@SteveMeiers]

Ditto, everything you said jjolson!

[@fredtaylor9792]

Seriously, I cannot express in words how your method of teaching is infinitely better at showing us what is actually happening on the fretboard. Why do so many other "beginner" lessons fail to even explain that the notes of one string continue onto the next every 5 notes? That seems like the FIRST thing you'd want to teach! The visuals are a language that's universal. Please, please understand that, from the very bottom of this complete stranger's heart, I truly do thank you for sharing your knowledge in this manner. I know it takes work to do it!

[@BrettRhodesLCSW]

Brilliant! I've been studying guitar for a little over 2 years now and your approach to the shapes of the pentatonic scales is finally getting me over that hurdle of being able to visualize all of this information all over the fretboard while I'm playing. Thank you! It's just so good. On top of that, you've given me a whole new way to travel horizontally ("the other diagonal") that I've not seen or heard mentioned anywhere else. I'm really looking forward to jamming with that pattern to find out all the goodies hidden therein. Huge thank you for making this material available. You're on to something very powerful here.

Excellent video! I memorized the 5 minor pentatonic boxes in a very “rote” way. The not-so-good news is, I use them the same way …always starting from the sixth string even if I don’t play a note.

Innovattive attempt at increasiing the joy of sounding good, better, and best on the instrument. I have seen many and this one is definitely unique. Anything that simplifies a students conceptualisation on the dynamics of phrasing single notes into a cohesive musical moment up, down and across the neck is genius to me. The key is practice, practice, practice.

[@fretscience]

Thanks. Unique isn’t always better, but I’ve observed that this framework combined with my approach to modes, triads, CAGED, and 3nps does speed up the learning curve quite a lot on the path to improvising freely and musically.

I use two patterns as well, but they’re grouped together different. The same mindset is involved,, though. Two patterns are all you need and you always know where the scale tones are because they always come out in the same place within the patterns, of which again there are only two. And then, minor 7th arpeggios; Same thing, just leave out the 4th.

I have a couple of guitars tuned to perfect 4th. With no 3rds tuning, I can play triads with only 3 shapes vertically or horizontally. Makes it very easy to visualize an infinite number of frets or strings with the same 3 shapes. Simplifies everything! Thanks for posting.

4ths tuning makes it quite hard to play a lot of classic riffs, but it’s definitely a lot simpler conceptually!

[@iljunjang]

The video that changed my 40-year guitar life. Absolutely original and fantastic. Keith is a genius. Now for the first time in 40 years, I'm gliding up, down, and across the fretboard. I even decided to memorize the fretboard (finally!) to take even more advantage of the stack and the rectangle (and of course as the result of Keith's advice). I've memorized 4 strings (it was easier than I thought) and just 2 to go. Keith, thank you absolutely. In the future, would you be able to tell us the rules of stacking the stacks and the rectangles laterally and vertically? I've figured out that the stacks are connected diagonally at the corner point, stacks and rectangles alternatve vertically, going up the fret one fret per pair. These are in your videos and cheat sheets. Then there are more rules which have not yet been explained. I've figured out the rules for the stack and the rectangle connecting laterally (rectangle's and stack's top are aligned when rect connects to stack's left side, bottom aligned when connecting to stack's right side). Then I got completely lost on how the rectangles (by themselves) connect laterally -- I eventually figured it out (there's a 2-fret overlap) but it would be terrific to hear the master himself explain these rules. This is so useful because now I see the shapes and I can see INSTANTLY where I can play. Thank you in advance.

[@fretscience]

Thanks for your kind words! In the video and cheat sheet, I laid out the connections that I use most often. For other movements, I tend to jump from root to root. If you want to find other ways of moving around the lattice of rectangle and stacks, I’d recommend drawing out an “infinite fretboard” of 12-18 frets and ~10 strings. Ignore the “warp” and use the rules you know to fill in rectangles and stacks. Then look for relationships that you think might be useful and practice applying them on the real fretboard. It’s a little more work, but you’ll find the connections that work best for you. 🎸🧪🤘

​@@fretscience Got it, Keith. I kinda did that, I think, and nearly had a stroke - but thankfully didn't. In the process, I found a couple of interesting'useful rules... I would love to be able to get around to writing it up one day for you and that could be a topic for another video for you down the line perhaps.

You can also send me a sketch if you find something useful that’s hard to put into words. I do enjoy visualizations 😅

I don't normally comment on videos but what a great tutorial I will be watching this a few more times.

Glad you’re here! 🎸🧪🤘

So many "aha" moments in one vid... thanks!

Iv been stuck in the intermediate level for years. This is exactly what I need to proceed Thanks for this

[@fretscience]

That’s great to hear…definitely check out my other videos…several of them build on this in interesting ways, and you don’t need to master each piece before learning about the next one because they all work together. 🎸🧪🤘

Very helpful, only wish I had sounds (some playing) so I can connect the head knowledge to the music. Knowing how all the notes sound in relation to the root seems super helpful while learning these. At least for a beginner with little ear training.

[@fretscience]

I agree, and I’ve started including more live demonstrations in my newer videos, but it’s also essential to do this with your own guitar. In addition to connecting shapes to sounds, it also ties in the physical movement. Glad you found it helpful! 🎸🧪🤘

This is a true game changer way to look at it. With the minor pentatonic you instantly have your 1 b3 5 and b7 all within the rectangle stack. And to have all those plus the 4th in the square shape. Amazing. Thank you for this 🙏

Glad it helped! 🎸🧪🤘

I recognize this voice from Waay and you are the best music teacher on the internet.

[@fretscience]

I don’t get the “Waay” reference, but I appreciate the sentiment! 🎸🧪🤘

[@WLVBS]

Great content! Very simple but powerful, and masterfully explained. Thanks, and looking forward to the next video!

[@fretscience]

Thank you, Julián!

[@mattcwatson]

Super helpful video! Mapping the fretboard with shapes makes so much sense, especially because I’m a bassist and don’t have to deal with the “warp.” Also, how is the first time I’ve ever heard of the hexatonic scale!? I love the 2nd/9th interval and try to incorporate it wherever I can.

Glad it was helpful! 🎸🧪🤘
