Visualise any guitar scale on a 15-fret diagram in any key, any tuning. Hear it back, download SVG/PNG, browse 192 dedicated scale reference pages (16 scales × 12 keys).
TL;DR — The free scale generator at myguitartutor.com visualises any of 16 scales in any of 12 keys on a 15-fret fretboard. Hear it back with Karplus-Strong synthesis, switch tunings, download as SVG or PNG. Plus 192 dedicated scale reference pages (16 × 12) — each indexable in search.
Scale references are one of the most-used resources in a working guitar lesson. The student gets stuck on a solo, you pull up the scale, you point at the notes, the student plays them, the solo lands. But the dance of finding a clean diagram for an obscure scale in an obscure key — that’s where a teacher’s time gets eaten alive.
The free scale generator fixes that. Sixteen scales, twelve keys, every tuning, audio playback, downloadable diagrams. One bookmark and you have the whole reference library on tap.
What it is
A browser-based scale visualisation tool:
- 16 scales across the seven major/minor family (major, natural minor, harmonic minor, melodic minor, major pentatonic, minor pentatonic, blues), four church modes (Dorian, Phrygian, Lydian, Mixolydian), plus the exotic group (Locrian, Hungarian minor, Phrygian dominant, Hirajoshi, Insen).
- 12 keys — every chromatic root.
- Tuning presets — Standard, Drop D, DADGAD, Open G, Open D, Half-step down, plus custom.
- 15-fret view — see the scale repeat across positions; identify how the patterns connect.
- Audio playback — Karplus-Strong synthesis plays the scale ascending and descending, so students can hear modes and exotic scales they’ve never heard in isolation.
- Root + interval marking — roots filled dark, other notes hollow. Optional interval labels (1, ♭3, 5, etc.) show scale-degree function.
- SVG + PNG download — vector for print, raster for slides.
- 192 dedicated scale pages — every scale × every key gets its own indexable URL (e.g.
/scales/c-major,/scales/a-minor-pentatonic), so search engines can surface the exact reference a student googles for. - No signup, no ads, no watermarks.
How to use it
Five steps to a scale reference:
- Open the scale generator.
- Pick a scale from the grouped dropdown (Major / Minor / Modes / Exotic).
- Pick a key — defaults to C; change for any chromatic root.
- Pick a tuning if you’re not in standard.
- Play it back to hear the scale, or download the diagram for a printable handout.
For pre-built reference pages, browse the scale index — every combination has its own dedicated URL, ready to bookmark or share.
Pro tips for tutors
Teach the modes by sound, not just by name
The fastest way to make a student care about modes is to play them. Set the generator to C Lydian, hit play. Then C Major, hit play. The student hears the raised 4th instantly. Then C Mixolydian — the flattened 7th lands. Sixty seconds and they’ve heard the modal palette; without audio, modes are an abstract concept that takes weeks to internalise.
Use the interval labels for scale construction lessons
Switch on interval labels and the student sees the scale formula laid out on the fretboard. The major scale shows 1-2-3-4-5-6-7. The minor pentatonic shows 1-♭3-4-5-♭7. Once the student can see the scale formula on the fretboard, they can derive any scale they need rather than memorising 16 separate patterns.
Print the scale, hand it over with the practice log
When you set a new scale as homework, print the diagram and tape it to the student’s weekly practice log. The visible diagram during home practice means the student doesn’t have to remember the fingering — they just look at the sheet. Practice completion rates on scale homework go up sharply with this single change.
Use Karplus-Strong playback for transcribing scales by ear
Set a scale to play back at slow tempo and ask the student to identify the notes by ear before looking at the diagram. This builds the connection between heard pitch and fretboard position, which is the bedrock of improvisation.
Where it fits in the teaching workflow
The scale generator lives in the technique and theory blocks of a structured lesson:
- Plan the lesson with a lesson planner, including a 15-minute technique block working a specific scale.
- Use the generator to pull up the scale during the lesson; print the diagram if the student is taking it home.
- Set scale-pattern homework with a target BPM, logged on the practice log.
- Track scale acquisition as a checkbox on the student progress tracker — major scale, pentatonic boxes, modes.
For the canonical CAGED-system reference of the major scale specifically: major scale positions.

Tools that pair with the scale generator
The scale generator is one of seven free browser tools for guitar tutors:
- Chord progression builder — build a backing chord progression in the same key and improvise over it using the scale.
- Metronome — set a tempo for scale practice, push the BPM week by week.
- Tuner — before any scale work.
- Chord encyclopedia — find chords from the same key for context.
- Reverse chord & scale lookup — drop in notes from the fretboard, identify which scale they belong to.
- Chord chart generator — print chord diagrams for chords derived from the scale.
Try it now
The free scale generator opens instantly in any browser. Bookmark it, browse the 192 pre-built scale pages, and never hunt for an obscure scale chart again.
If you’re running a tutoring practice past the point where free tools alone are doing the job, our bespoke teaching platform builds the same scale library into a per-student practice surface — every scale you’ve ever assigned them, with audio, in their app, on your domain.
