Octave visualizer
Choose a note to see where it sits across the whole fretboard.
This tool is for anyone who knows the notes in theory but still struggles to find them quickly on the neck while playing, as much as for anyone who wants to actually see what an interval is rather than calculate it on paper. Picking a single note instantly reveals every place it sits across all 6 strings; picking a second note also shows the exact interval between them — the same pair of notes can become either a note-finding drill or an interval lesson, depending on what you're after. What you gain is a mental map of the neck built note by note, rather than memorized position by position.

How to use the visualizer
Every occurrence of the same note (say, every E) is highlighted at once across all 6 strings and up the whole neck: that's what lets you see at a glance how the same note repeats in different places, an octave apart or even on the same octave across neighboring strings. Adding a second note automatically works out and displays the exact interval between them (a third, a fifth, and so on), whatever position each one is picked from.
This idea of the same note repeating at several spots on the neck is exactly what makes the CAGED shapes possible: each chord shape corresponds to a different place where the same root note sits. The octave visualizer makes that mechanism explicit, note by note, before ever moving on to full chords.
Practical tips and common mistakes
- Don't try to memorize every position of a note at once: focus first on the low E and A strings, the two most commonly used as reference points, before branching out to the others.
- Use the two-note function to check a hunch rather than to memorize by rote: if you think an interval is a fifth, select both notes and check — it's faster than counting semitones in your head every time.
- Spot the fixed-distance octaves first (same string, 12 frets up, or two strings lower/higher and two frets up): those are recurring movable shapes, much quicker to retain than an isolated position.
- Once you can spot a note quickly on the neck, check that you can also find it inside a real scale or chord: recognizing an isolated note is a first step, not an end in itself.
Concrete example
Select E with no second note: the grid highlights six or seven E positions across the whole neck, including open strings. Then add B as the second note: the tool instantly shows "fifth," the same interval that structures the circle of fifths and the way a key's compatible chords are built.
