Guitar Intervals Unleashed
Take your fretboard training beyond the book with the Guitar Intervals Unleashed mobile app series, available on Google Play and the App Store. Based on the book of the same name, these interactive training apps help you master notes and intervals through active practice rather than memorization.

The namesake app, Guitar Intervals Unleashed, is the perfect place to begin your interval training.
Why These Apps?
Most guitar training emphasizes memorizing chord and scale shapes. While this helps develop muscle memory, it does little to improve interval recognition and fretboard visualization.
The NANDI Method takes a different approach. Instead of relying on memorization, it trains you to recognize notes and intervals using the natural interval relationships found on the guitar.
Unlike reference apps that simply display answers, every app in the Guitar Intervals Unleashed series is interactive. You’ll identify notes and intervals on blank fretboard diagrams, reinforce your understanding through repetition, and use the optional Hint feature whenever you need guidance.
Apps Included
ID Natural Notes
Learn to identify natural notes using the fourth pattern described in the Reading the Fretboard lesson.
ID Natural Notes:
This app will show you how to interpret the fourth pattern to identify natural notes on the fretboard. You can check out the Reading The Fretboard lesson to learn more about the fourth pattern.
ID Fourths:
Practice reading notes and intervals across the strings in fourths.
• Train with interval numbers or note names.
• Practice natural, sharp, and flat notes.
• Hint mode displays the complete fourths pattern.

ID Fifths:
Practice identifying notes and intervals in fifths.
Because fourths and fifths are inversions, reading the fourth pattern in reverse reveals the fifth pattern.
ID Minor Sevenths:
Master the minor seventh pattern by skipping every other interval in the fourth pattern.
Practice:
• Interval numbers.
• Natural notes.
• Skipped-string relationships.

ID Major Seconds:
Develop major second recognition by following the inverse of the minor seventh pattern.
Train from any root note or interval across the fretboard.
ID Intervals – Left to Right:
Practice identifying intervals between string pairs from lower to higher strings.
Features:
• Nine string-set combinations.
• Interval or note training.
• Hint mode to reinforce interval relationships.

ID Intervals – Right to Left:
Reverse the previous exercise by identifying intervals from higher to lower strings.
Using the NANDI Method, you’ll learn to recognize interval relationships through logic instead of memorization.
CAGED Octaves- Intervals/Notes:
Master octave locations across the entire fretboard using the interval relationships between string pairs instead of memorized octave shapes.
Practice begins with roots on the open A, G, E, and D strings, as well as C on the 1ˢᵗ fret of the B string. Using the NANDI Method, you’ll learn to locate every octave from the lowest to the highest fret, then navigate back to the starting root.
For example, starting from C on the B string, use the minor 7ᵗʰ relationship to locate the octave on the A string two frets higher. Repeat the same process from the A string to the G string to continue tracing octaves across the fretboard.
Train with both interval numbers and letter notes, making octave recognition fast, logical, and independent of memorized patterns.
Interval Architecture:
Discover how interval locations can be calculated using simple fretboard math instead of memorization.
This app teaches you to locate intervals on adjacent and non-adjacent string sets by applying the interval relationships that naturally exist between the strings. You’ll quickly understand why an interval appears two, three, or four frets above or below the root.
For example, the E–D strings are a minor 7ᵗʰ (10 half-steps) apart. To locate a minor 6ᵗʰ (♭6 = 8 half-steps) on the D string, subtract 8 from 10, leaving 2. The result shows that the ♭6 is found two frets below the root.
Through repeated practice, you’ll learn to derive interval locations anywhere on the fretboard using logic rather than rote memorization.

Prefer learning by writing? Companion workbooks for both right- and left-handed guitarists are available on Amazon, with structured exercises to reinforce the interval concepts taught throughout the NANDI Method.
