Major Scales for Guitar and Piano
For any musician, especially beginners and intermediate students, learning the major scales for guitar and piano is an essential step toward true fluency. It’s not just about technique — it’s about understanding the structure of music itself.
Unfortunately, far too many students skip this crucial step. That’s why Henry Bahrou, guitarist, music theorist, and director of Grosse Pointe Music Academy, created the Scale Mastery Workbook: The 15 Major Scales for Guitar and Piano — a comprehensive, practice-driven workbook designed to help musicians memorize, write, and internalize all 15 major scales using a proven 30-day repetition system.
Why Learning Major Scales Is Essential
Major scales are the DNA of all Western music. From understanding chord progressions and reading sheet music to soloing and composing, knowing these scales gives musicians the tools to communicate in the universal language of music.
While most theory resources cover the seven basic major scales, the Scale Mastery Workbook goes further — covering all 15, including enharmonic equivalents like C♯ and D♭. This clarity is vital for both practical musicianship and theoretical understanding.
Introducing the Scale Mastery Workbook
Built with both piano and guitar learners in mind, this workbook presents each of the 15 major scales in a clear, approachable format using:
- Standard notation on treble clef
- Guitar tablature for each scale
- Piano keyboard diagrams for every key
- Workbook pages for daily written recitation
Designed to be used over a 30-day period, the book’s goal is simple but powerful: turn scale knowledge into second nature.

Who This Workbook Is For
Though it’s titled for guitar and piano, this resource is perfect for:
- Students learning music theory
- Musicians looking to solidify their scale knowledge
- Music teachers seeking a classroom companion
- Adult learners returning to music
- Parents supporting kids in structured lessons
The workbook is most effective for students ages 8 and up and works best with the guidance of a music teacher — although self-taught musicians with basic theory skills will benefit too.
Why Henry Bahrou Wrote This Book
“As a teacher and director at Grosse Pointe Music Academy, I saw a common problem — students could play scales, but few could spell them or write them confidently. Especially guitarists. This workbook addresses that exact gap,” says Bahrou.
Unlike books overloaded with jargon, Scale Mastery Workbook is about practice over theory, helping learners master the 15 major scales through structured repetition and visualization.
What’s Inside the Workbook
- All 15 major scales in standard notation + TAB
- Clear piano diagrams for each scale
- Treble clef-only workbook sheets for daily scale writing
- A full 30-day repetition plan laid out to promote retention
- Clear, uncluttered layouts for student-friendly learning
The format is visually clean and direct — making it easy to stick to the plan and see real progress.
Why 15 Major Scales?
If you’ve only learned 7 major scales, you’re missing out. Music isn’t written only in “easy keys.” Learning all 15 (including enharmonic equivalents) gives you the ability to play and think in any key — which is essential for reading, transposing, composing, and improvising.
Benefits of Daily Written Recitation
Writing music by hand strengthens the brain’s connection to the material. When students physically write each scale daily — as the book instructs — they internalize spelling, interval patterns, and scale shapes more deeply than passive review allows.
After 30 days, most students can recite any major scale from memory, write it quickly on staff, and visualize it on their instrument.
Not Just for Guitar and Piano
The layout of the workbook uses guitar tablature and piano keys because they’re the most visual instruments for learning. But the theory applies to any instrument. Brass players, vocalists, violinists — anyone can benefit.
Bahrou often says, “Even if piano isn’t your instrument, it should be your reference point. Every musician should know piano.”
Support from Grosse Pointe Music Academy
While not officially part of the curriculum, this workbook is endorsed by Henry Bahrou, director of Grosse Pointe Music Academy — a community leader in private music education. It’s frequently recommended to students who struggle with scale memorization or music reading.
Teachers at the academy have shared that the book fills a long-missing gap: one that bridges the divide between playing a scale and understanding it fully.
What Makes This Workbook Unique?
- It’s active, not passive: you don’t just read scales — you write them.
- It’s visually guided: great for visual learners, thanks to TAB and keyboard diagrams.
- It’s simple: no overwhelming theory, just practical repetition and memorization.
- It’s complete: all 15 keys — not just the “easy” ones.
What Students and Teachers Are Saying
While formal reviews are still gathering, teachers using the workbook have reported:
“This is what I’ve been needing to give my students structure.”
“Clear, clean, and practical — especially for guitar players.”
“The daily writing makes a huge difference in retention.”
