Most guitar players learn scales, chords, and theory through years of trial and error—but Rick Beato has a shortcut that could save you months of confusion. Drawing on decades of experience as both a student and teacher at prestigious music institutions, he reveals specific notes to avoid on major and minor chords, and shows how to build beautiful-sounding lines using just six notes instead of the full seven-note scale.
The "Avoid" Notes Every Jazz Guitarist Knows
Beato's mentor, Steve, taught him one rule that baffled other guitar students: don't play the fourth on a major chord, and don't play the sixth on a minor chord. At first glance, this sounds like arbitrary advice—but it actually describes which scale degrees create dissonance against certain chord types.
When playing a major seventh chord—like D major 7—the fourth note of the scale (the G in this case) creates an ugly, clashing sound against the root. It's not that you can never use that note; it's that most players don't understand when to use it. The solution? Simply skip it entirely.
The same principle applies to minor chords. On a B minor 7 chord, the sixth note of the scale (G) creates unwanted dissonance in certain contexts—particularly when moving through chord progressions like ii-V-I.
Hexatonic Scales: The Secret Weapon
Instead of memorizing complex scale fingerings across the entire neck, Beato suggests using hexatonic scales—six-note scales that exclude those problematic notes. For D major, you play the first three scale degrees (1-2-3), skip the fourth entirely, then continue with 5-6-7.
This creates a D major hexatonic scale: D-E-F# - skip G - A-B-C#. The result is a six-note scale that sounds clean and modern over any major chord. You can find these patterns in Beato's book, which maps them across the entire fretboard.
The same principle works for minor keys. B minor hexatonic excludes the sixth note (G natural or G sharp depending on whether you're thinking Dorian or Aeolian). The notes are B-C#-D-E-F#-A—beautiful when played as chords or single-note lines.
Adding Color Without Cluttering
Once you've mastered these six-note scales, you can start adding color tones to basic triads. A simple approach works like this: take your minor chord and add the ninth. For a B minor 7, that gives you B-D-F-A-C#—a lush, modern sound.
Then try adding the natural sixth—the note Steve told everyone to avoid. Used sparingly, it creates gorgeous tension against the chord. The key isn't avoiding these notes entirely; understanding how they function in context.
When playing D major 7, experiment with the sharp eleven (the sharpened fourth). It sounds better than the plain fourth. But when adding that major seventh to the chord, watch out—that note becomes extremely dissonant.
Counterpoints
Some music educators might argue that rigidly avoiding these notes oversimplifies musical expression. Great jazz players often deliberately use "avoid" notes for expressive purposes—the dissonance is intentional. Additionally, hexatonic scales work beautifully in certain contexts but may not fit every musical style; rock guitarists and classical players might find the approach too restrictive for their needs.
Bottom Line
Beato's core insight—that understanding which notes clash against your chord type is more useful than memorizing full scales—represents genuine practical value. His decades of teaching experience shine through in these shortcuts. The biggest weakness: this article, drawn from a rambling video, could have been tightened significantly. The actual theory content is buried under excessive self-promotion about course bundles and promotional offers. For readers willing to dig past the noise, there's a solid framework for understanding guitar theory without years of trial and error.
