You're Stuck in the Note-by-Note Phase
Most percussionists hit a plateau where they can play individual notes but struggle with fluency, consistency, and confidence. Here's why—and how to break through.
Spacing Inconsistency
You know the notes, but your hands don't know where to go. Every chord shape feels like a new puzzle across marimba, vibraphone, and xylophone, and mistakes happen under pressure.
The Solution:
The Anchor Intervals System teaches your hands to recognize patterns, not memorize positions. You'll develop spatial awareness that works across all keyboard percussion instruments and all keys.
Practice Without Progress
You spend hours practicing but can't tell if you're actually improving. You repeat the same mistakes without knowing why.
The Solution:
The Map-Making Loop gives you a diagnostic framework to identify problems, test solutions, and track real progress—not just time spent.
Performance Anxiety
You sound great in the practice room but fall apart in auditions or performances. Nerves expose every weak spot in your technique.
The Solution:
The Clarity-First Method builds bulletproof fundamentals that hold up under pressure. You'll develop the confidence that comes from true mastery.

What Students Are Saying
Real results from percussionists who've mastered the Self-Correcting Framework
"Spencer Perilloux's work serves as a tremendous asset to the teaching of percussion for the modern player. Information such as sticking advice, ideas of generating the best tone for each instrument, listening examples from professional players, and gaining an overall sense of phrasing—this should be considered essential to all percussionists in the high school band program."
Chris Chapman
Professor of Music, Director of Bands, Central Michigan University
"Spencer Perilloux is a highly accomplished performer and pedagogue who has created an invaluable resource for secondary school percussionists. This comprehensive collection of guidance and the accompanying demonstration videos are not only a must-read and watch for any student auditioning for Illinois All-State, but also for any young percussionist who is looking to take the next step in advancing their technique and musicianship."
