You don't need just scale boxes.
You need an effective system to:

  • know what scale to use
  • see it quickly wherever on the fretboard in all keys

This part of the DCLS course will teach you major scales and how to find them fast on the fretboard, but also how to identify keys and key changes in chord progressions. 

Combining an improved caged system and major pentatonics, DCLS will get you to major scales with incredible ease. And with 10 scale boxes in total!

You will learn:

  • Major Scales
  • How to find them on the fretboard in all keys
  • Analyze a chord progression
  • Know what key to play in
  • Play on key changes
  • Diatonic harmony theory 
  • Easy 10 boxes DCLS system

Why DCLS works

To be a fluent improviser you need 3 things:

  • Be able to see scales fast on the fretboard
  • Know what scales to use on different chord progressions
  • Have the technique to express yourself  

My "Diesels" system will not only help you memorize the scale boxes and know which scale goes where, but also to see them at a glance on guitar.

10 boxes for all scales

You want a single simple system for all your scales.

DCLS improves the CAGED system and combines it with pentatonics and major scales to map the whole diatonic fretboard. 

So with 10 boxes and a simple system you will cover Pentatonics, major scales and modes.

All 3 essential sounds of modern improvisation clearly visible and interconnected on the fretboard. 


  • Master Major Scales
  • Learn to decode chord progressions
  • Learn how keys work
  • Learn to navigate key changes
  • Almost 3 packed hours of video
  • 21 step by step lessons10
  • 10 video backing tracks with a real band 
  • Downloadable PDF with support material
  • Clear explanation of all concepts
  • Innovative and easy DCLS (diesels) approach
  • Online - yours forever

The DCLS approach works best when you take it from start to end!

Even if you know pentatonics, you might want to solidify your foundations and apply the system to easier concepts first.

Brush up major and minor pentatonics on Part 1 then master major scale and move up to Modes on part 3

Don't just take my word for it

Lovely students, lovely words.
Alberto's DCSL 1 - Pentatonics Course is very straightforward & digestible.  I wish I'd had these handy & dynamic insights at my disposal 56yrs. ago!  It would have saved me a lot of floundering.

I first found Alberto's lesson on "Little Wing". It was a great lesson!... I would not hesitate to recommend any of his instructional videos. 

Bill W.

"The courses are REALLY GREAT! I learned with much ease because the teaching style is very thorough. And I love the arrangements, to me it's like being at a concert! 


Alberto is not only a masterful guitar player, but also a wonderful teacher. What stands out is his systematic approach, paying attention to the details, and presenting the material in a very accessible way. Lessons are structured cohesively and designed in the right volume to ensure steady progress without overwhelming the learning experience.

I have known the Minor Pentatonic scales for years, but have never been able to make them sound any good until I went through your course DCLS. The backing tracks are fantastic! I continually go back to them and try new things!

John T.

The lessons are not only informative but also engaging... incredibly helpful, especially for a beginner like me. I've made significant progress in a short time, and that's largely thanks to a perfect balance between being clear and patient. 

Alon M.

I love the guitar courses I registered for.. The split screen is very helpful.I am a better guitarist, thanks to your guitar courses.. A fantastic arranger of various genres for the guitar.

Jimmy H.

Il metodo DCLS offre un’ulteriore punto di vista su argomenti spesso trattati in modo troppo “scolastico”. Ciliegina sulla torta le basi in tutte le chiavi suonate dal vivo.

I know Major scales, why should I take this course?

  • It is possible that you know the scale patterns but not as in depth as you would with DCLS system.
  • Learning major scales with DCLS helps you visualize them much faster on the fretboard
  • This course also teaches you to understand what key a chord progression is in, therefore what scale to play
  • The course also explains how to deal with key changes, a very challenging subject
  • It is quite common to use only a couple of boxes and not even across all strings. Sometimes you feel like you're using always the same few notes in the same 2 boxes. This course helps you play on all the fretboard, on all the strings, in all common keys. 

I know Major scales, can I just go to part 3 on Modes?

DCLS is a modular approach, and learning or re-learning the major scale this way will help you a great deal to learn modes on the fretboard.
Nonetheless if you have a very strong knowledge of the diatonic harmony, harmonic analysis and major scales all over the fretboard, DCLS part 3 provides a full recap of the system and you can start directly there.  

What does DCLS mean?

DUAL CAGED LAYERED SYSTEM - and it's pronounced Diesels

What is DCLS?

DCLS it's a complete improvisation system that starts from pentatonic scales and works its way up to modes. It's an improvement of the CAGED system. There are a few areas where CAGED is a bit uneffective, especially on minor scales and DCLS fixes that. But unlike CAGED, DCLS is designed to work with modes as well.
It's modular, so you will have only 10 basic boxes, and everything else will build on these just by changing a few notes. 
This is unique and speeds up the process of understanding scales and modes, recognising them on the fretboard and learning their sound. 

Is it better than CAGED? 

CAGED has limits, especially in minor keys. The Diesels system builds on CAGED but improves its effectiveness, making finding pentatonics, major and minor scales, including modes...a piece of cake. 

What are part 1 and 3 about? 

Part 1 is about the Pentatonic Scale, Major an Minor. You also learn the basic of the DCLS approach to fretboard visualization.
Part 3 is about modes. The DCLS system is great with modes, let's say it makes them as easy as memorize and as usual to see on the fretboard. Modes is where the DCLS system really shines! 
Part 4 Still in the works, when released will be about more complex scales, like modes from the melodic minor, altered scales and superimpositions of pentatonics and triads. 

Will I have a discount if I want to get the full course? 

Certainly! The full course is available as a complete bundle HERE. But if you prefer to start with just this part, and then decide to purchase the entire course bundle you will have a proportionate, substantial discount!
