Start playing the solos you hear in your head.

You know the feeling.

It’s your moment to solo. All eyes are on you – and out comes… the same lick. The same blues line you’ve played a hundred times before. Reliable. Safe. Maybe a little bit disappointing, if you’re honest with yourself.

You’ve heard what you want to sound like. Scofield twisting a phrase just far enough outside the changes that it makes your head turn (and maybe do the “stank” face). Robben Ford landing a note that shouldn’t work, except it does. Oz Noy, Larry Carlton, Jimmy Herring – that “wonky,” slightly off-centre sound that makes a solo feel like a statement instead of a scale exercise.

You’ve probably even tried to get there. Maybe you dabbled with side-stepping, or looked into the diminished scale, or messed around with melodic minor. And what happened?

It sounded wrong. Not “outside and interesting” wrong – just wrong wrong. So you backed off, and went back to the pentatonic box, because at least that sounds like music.

That’s not a talent problem. It’s a systems problem – and it’s exactly what this course fixes.

You're stuck inside the pentatonic bubble

You’re confident in the first box. Comfortable enough in the other four. Maybe you know Dorian and a few “outside” scales. You can find the intervals in a chord if you take a second to think about it. In other words – you’re not a beginner. You’re stuck.

And that’s a more frustrating place to be than being a beginner. You have the technique. You have some of the theory pieces. But something isn’t connecting, and it shows up in a few familiar ways:

Here's the part most guitarists never figure out on their own

Playing “wrong” notes on purpose is not a note-choice problem. It’s a confidence problem.

A note played with hesitation always sounds like a mistake – even if it’s theoretically correct. 

The exact same note, played with commitment and resolved deliberately back into the changes, sounds like intention. Like a choice. Like the “head-turning” moment you’ve been chasing.

That’s the gap. Not more scales. Not more theory. A system that gets the sound into your ears, the shape under your fingers, and the confidence to commit to it when soloing – every time.

Mastering the Diminished

Beautifully Twisted Sounds for Blues, Fusion & Beyond

A strategic roadmap for intermediate guitarists to level-up their outside playing

This isn’t yet another lick pack that you’ll never use in the real world. It’s not a theory dump. It’s a comprehensive system for using the diminished scale – and the concept of tension and release underneath it – to permanently expand what you can do in a solo.

You’ll move from running scales to what the best players actually do: singing through your instrument. Phrasing. Chord-tone targeting. Deliberate practice built specifically to isolate and strengthen the skills that don’t show up when you’re just noodling.

What you’ll walk away with:

No more disconnected theory concepts or aimless practice.

With Mastering the Diminished, alongside a commitment to practice, within weeks you’ll be able to start playing beautiful, twisted solos using the sounds of the diminished scale and its harmony.

This isn’t a course you binge in a weekend and forget by Friday. Mastering the Diminished Scale is built as a 90-day pathway – seven modules released progressively, giving you time to actually get the techniques under your fingers before the next stage builds on it. Rushing through scale theory without practicing it is how most players end up right back where they started. This course is designed so that doesn’t happen to you.

By the end of the 90-day course you’ll have the tools to tackle static grooves, II-V-Is, blues and jazz progressions – all with more freedom than you ever thought possible.

You’ll also go in-depth into the harmony so you can improvise with a whole new set of colourful chords and even start writing your own chord progressions.

A 90-day journey, not a data dump. Modules unlock every 30 days so you build real technique, one stage at a time.

A taste of what's inside Mastering the Diminished

These aren’t a bunch of dry lessons – every concept is taught through the lens of beautiful back tracks that you’ll love playing over time and again. Shuffle Blues, Rock Fusion, Jazz Fusion, Latin Bossa, Slow 12/8 Blues, Funk and more – all with lashings of groove and real instruments – designed to inspire you to improvise with real pocket.

Is Mastering the Diminished right for you?

  • You’re confident with blues and pentatonic playing

  • You’ve got at least the first box down cold (and you’re fairly comfortable in the other four

  • You’re confident finding the intervals in a chord (even if it takes you a second)

  • You know the notes on the neck without much struggle

  • You listen to guys like Robben, Scofield, Henderson, Jimmy Herring or Oz Noy and think, “I want some of that outside sauce in my playing!

  • You’ve tried to play “outside” but it sounded wrong

  • You’re ready to stop saying “this is the year I’ll learn how to improvise more freely”
  • You’re a relative beginner – this course assumes a foundational knowledge of blues soloing, chords and intervals and builds on top of that
 
  • You’re looking for a shortcut or “hack”. This course is a comprehensive system – it’ll take real, deliberate practice. If you’re after a 15-minute fix, this isn’t it. If you want a genuine lasting shift in how you solo, it is
 
  • You want a pack of licks to memorise and copy – licks get you one sound in one context. This course teaches the system underneath them, so you end up generating your own lines
 
  • You’re not willing to put in 2 hours a week (spread out)
 
  • Outside sounds don’t give you the “stank face”
 

Great value for guitarists who are serious about progress

When you join Mastering the Diminished you get nearly 5 hours of video instruction – no fluff, structured as a complete pathway, not a random pile of lessons and licks with no context. 

To put that in perspective, here’s what it would normally cost to get material like this:
 
  • Private tuition (twice a month, over the 3–6 months this course covers): $500 – $1,000
  • A professional music school route covering the same ground: $10,000 – $23,000
 
You’re getting the same depth of material – built from over 25 years of professional playing and teaching, identifying the exact same sticking points guitarist after guitarist runs into – for a fraction of either.
 
When you join Mastering the Diminished, you’ll get lifetime acces to all course materials and the private student community. This includes:
 
  • An incredible 114 in-depth video lessons, 20 full solos, over 30 example lines and 3 in-depth performance études
  • Guitar Pro & PDF tabs for every solo and example – meticulously transcribed, so you’re never guessing at a phrase or a fingering
  • 5 accompanying PDF books ($60 total value)
  • 8 professional backing tracks ($50 total value) – real drums, real bass, real guitar. No AI-generated backing tracks. These are built to feel like a real bandstand in a variety of styles, so the outside sounds you’re building actually get tested against a real rhythm section, not a static loop
  • Access to the players’ forum – ask questions, get answers from me and other students, post your own playing for feedback. You’re not learning this in isolation
 
On top of this, you’ll also be backed by my 7-day money back guarantee. No stress, no worries, no pressure. If you don’t love this course, simply email us within 7 days (team@steveallsworth.com) for a full refund, no questions asked.

FAQs

A new module unlocks every 30 days over your first 90 days with the course. This isn’t a restriction – it’s the format working as intended. Mastery comes from practicing each stage before adding the next layer, not from watching/reading through material quickly. Students who get everything at once often feel overwhelmed and retain less. This pacing is designed to fix that.

You need some foundation – basic chord/interval knowledge and comfort with blues scales – but this isn’t a music-theory lecture. We’ll eventually go quite deep, but theory is broken into digestible pieces, taught in the order you actually need it, built for a guitar player’s brain rather than a classroom.

This course isn’t built for beginners – it assumes you’re already confident with basic blues soloing, know your chord intervals, and are comfortable with at least the first pentatonic box. If that’s not you yet, get that foundation in place first; this course will make far more sense once you do.

You’re not learning this in isolation. You’ll have access to the players’ forum, where you can ask questions, get feedback on your own playing, and see what other students are working on.

Not at all. Everything – video lessons, tabs, backing tracks, PDFs – is designed to be simple to access and use. If you can play along to a YouTube video, you can use this course.

That’s the whole point of the course. A lot of “outside” playing falls apart the moment it has to happen in real time, at tempo, in front of people. The work we do here is built specifically to close that gap – not just teach you the notes, but get you comfortable committing to them live.

Are you serious? (Only kidding). The fact is, you don’t need hours a day to make progress – you need a clear plan, focused sessions and consistency. Our 90-day course is designed so that even 15-20 minutes. 

Don’t worry! Although we release each module every 30 days, you can still take the course at a slower pace to fit in with your schedule. You’ll have lifetime access to the whole course, so you can come back to any lesson time and again.
