Make sense of
the guitar neck.

See which notes to play, tap to hear them, and connect patterns across the neck. Start with five notes in A minor and build from there.

See the notes.
Make the connections.

See it and hear it

Choose a key and scale, then tap any note to hear it. Start with five-note patterns and explore more sounds when you're ready.

Connect familiar shapes

CAGED uses the C, A, G, E, and D chord patterns as landmarks. See how scales fit around them, then compare playable chord grips and fingerings.

Follow the chord changes

Enter a sequence of chords and highlight the notes in each one. Use them as landing points when you practice a melody or solo.

Why I built FretScope.

I've played guitar for more than 30 years, in cover bands and bands playing original music. Even after all that time, I still hadn't fully learned my way around the fretboard.

I built FretScope to get that information out of my head and onto the screen. I can filter down to the notes and patterns I want to work on, without having to remember which fret is which every time I look at my guitar. That leaves more room to learn the shapes, understand the connections, and just play.

Pentatonic scale guitar — beyond the box

Most guitarists learn one pentatonic box shape and stay there for years. FretScope shows how all five positions connect across the neck so players can move instead of getting trapped.

What is a guitar scale chart?

A guitar scale chart shows which frets and strings belong to a scale in a given key. Traditional charts are static images. FretScope updates live as you change the root note, scale type, or position.

How to learn guitar scales effectively

The most effective approach is to connect scales to chord shapes and chord tones. FretScope links every scale degree to the underlying harmony so players can see what matters inside the shape.

CAGED system explained

The CAGED system organizes the guitar neck into five repeating shape patterns derived from open chord shapes moved up the neck. These familiar chord shapes give you landmarks for finding scale and chord notes.

Guitar modes explained

Modes make more sense when the changing notes are visible on the fretboard. FretScope helps players compare major, minor, Dorian, Mixolydian, and more inside familiar position windows.

Guitar arpeggios and chord tone targeting

Type a progression, click through each chord, and watch the chord tones move in real time. That makes it much easier to practice melodic soloing instead of just running scales.
