The Transformation
Here's what changes when you master the Self-Correcting Framework
Before: The Struggle
- ❌Spending hours practicing without clear progress
- ❌Memorizing each chord shape individually
- ❌Feeling lost when sight-reading new music
- ❌Mistakes appearing randomly under pressure
- ❌Relying on your teacher to diagnose every problem
- ❌Dreading auditions because you can't trust your technique
After: The Breakthrough
- Practicing with clear, measurable goals
- Recognizing patterns across all keys instantly
- Sight-reading confidently with spatial awareness
- Understanding exactly why mistakes happen—and fixing them
- Diagnosing and solving your own technical problems
- Performing with confidence backed by bulletproof fundamentals
What You'll Master
Five integrated systems that build complete mallet percussion fluency
The Dual Approach
Master both pathways to fluency
Learn to navigate the keyboard through both Intervals and Shapes. The Interval Method builds spatial awareness and pattern recognition. The Shape Method develops visual-motor connections. Together, they create complete fluency that works in any musical context.
- Interval-based navigation for sight-reading and transposition
- Shape-based recognition for fast, automatic execution
- When to use each approach for maximum efficiency
The Foundation
Hardware that holds up under pressure
Build bulletproof technique from the ground up. Master German Grip, Low Hammer Stance, and the Two-Lane Highway concept that organizes your hands for maximum efficiency and consistency.
- German Grip fundamentals for power and control
- Low Hammer Stance for consistent contact point
- Two-Lane Highway: organizing left and right hand lanes
The Practice Strategy
Software that makes every minute count
Stop wasting time on unfocused repetition. The Map-Making Loop teaches you to diagnose problems, test solutions, and track real progress. The Clarity-First Method ensures every rep builds skill, not just muscle memory.
- Map-Making Loop: identify → isolate → solve → verify
- Clarity-First Method: slow, deliberate practice that transfers to speed
- Progress tracking systems that show real improvement
Music Theory Essentials
The mental framework for fluency
Learn the theory that matters for percussionists. The Anchor Intervals System teaches you to recognize and navigate intervals instantly. The Mental Shift transforms how you think about chord construction and voicing.
- Anchor Intervals: the 12 building blocks of all keyboard navigation
- Chord construction and voicing for percussionists
- The Mental Shift: from memorization to pattern recognition
The Systems
Proprietary frameworks that accelerate mastery
Access the complete toolkit of proprietary systems: Pathfinder for efficient hand paths, Interval Matrix for pattern recognition, and Shift Efficiency for seamless position changes.
- Pathfinder System: optimize hand paths for speed and accuracy
- Interval Matrix: recognize patterns across all keys instantly
- Shift Efficiency: move between positions without hesitation

Frequently Asked Questions
What if I'm a complete beginner?
This course is designed for intermediate to advanced students who already have basic mallet technique. If you're just starting out, I recommend beginning with private lessons to build foundational skills first.
Is this course for two-mallet or four-mallet playing?
Unlock the Keyboard focuses on two-mallet technique. The course builds foundational fluency with interval navigation, shape recognition, and the Self-Correcting Framework using two mallets. While many photos show four-mallet performance, the instructional content is specifically designed for mastering two-mallet playing across marimba, vibraphone, and xylophone.
How is this different from other mallet methods?
Most methods focus on exercises. This course teaches you systems—diagnostic frameworks that help you understand why something works, not just what to practice. You'll learn to solve your own problems, not just follow instructions.
What's the difference between the ebook and the course?
The ebook ($28) is a comprehensive PDF guide with all exercises and the Self-Correcting Framework principles. The course ($149) includes everything in the ebook plus in-depth video lessons, play-along practice tracks, and video demonstrations of all techniques. Both come with lifetime access.
What if it doesn't work for me?
You're protected by a 30-day money-back guarantee. If you complete the first section and don't see improvement in your practice quality, just email me for a full refund—no questions asked.
Can I get help if I get stuck?
Yes! Course students get access to email support. For more intensive guidance, you can also book private lessons at a discounted rate.
