The Ultimate Harmonic Engine for String & Key Musicians.
Interval Matrix Pro® is not just a chord and scale dictionary—it is the DNA of music, visualized, where each interval has its own color. Whether you are composing for a string quartet, shredding on an 8-string guitar, or laying down grooves on a 6-string bass, this app unlocks the geometry of the fretboard and keyboard like never before.
Stop memorizing shapes. Start mastering the matrix.
Most apps are limited to standard 6-string guitars. Interval Matrix Pro® breaks the mold, offering a unified harmonic language across 14 different instruments.
Supported Instruments:
Guitar: 6-String, 7-String, 8-String
Bass: 4-String, 5-String, 6-String
Orchestral Strings: Violin, Cello, Double Bass
Folk: Mandolin, Banjo, Ukulele
Keys: Full 88-Key Piano Visualization
Key Features:
The Master Database: Access a massive library of chords and scales, from Western standards to exotic ethnic modes and Best Guitar Channel Exclusives (like the Swiss Army Knife and Mixoblues scales).
The Matrix View: Instantly toggle between Note Names (C, E, G) for reading charts and Intervals (1, 3, 5) to understand the function and shape of any voicing.
Universal Translation: Select a chord on the Piano and instantly see how to play it on a Banjo, 7-String Guitar, or Cello.
Welcome to the official support hub for Interval Matrix Pro®. Developed by Best Guitar Channel, this tool is designed to be the final word in harmonic visualization.
Q: How do I change instruments? A: Tap the instrument icon in the top menu. You can cycle through all 14 instruments instantly. The app remembers your selected scale or chord and translates it to the new neck or keyboard layout in real-time.
Q: What is the difference between "Notes" and "Intervals"? A:
Notes View: Shows the specific pitch (e.g., C#, F, Bb). Use this when reading sheet music or communicating with other band members.
Intervals View: Shows the scale degree (e.g., 1, b3, #4). Use this to unlock the "shape" of the sound. This is the secret to transposing ideas to different keys and instruments.
Q: Does this work for Left-Handed players? A: Yes. You can toggle "Lefty Mode" in the settings to flip the fretboard visualization.
Q: I see scales here that aren't in other apps. A: Interval Matrix Pro® includes exclusive content curated by Best Guitar Channel.
The Swiss Army Knife Scale: An 8-note hybrid (1, b3, 3, 4, #4, 5, b7, 7) designed to work over Major, Minor, and Dominant chords.
Mixoblues: The perfect fusion of Mixolydian and the Blues scale for modern rock and jazz fusion.
Q: Why are there so many "No 5" chords? A: In modern guitar and orchestral arranging, the 5th is often omitted to create cleaner, more open voicings (Shell Voicings). We include these mathematically distinct structures to give you more creative freedom.
Q: I found a bug or I have a feature request. A: We are constantly improving the Matrix. Please email us with your device model and a description of the issue.
