Chord chart import
Turn a Chord Chart Photo into a Guitar Practice Plan
A standard chord chart identifies the harmony but does not usually explain how to practise it on the guitar. GuitarHarmonyLab imports a clear photo or PDF, lets you verify the detected grid, then proposes harmonic guidance and fretboard work built from the validated chords.
In one sentence
From paper to fretboard, without retyping the full chart
Import a chart you are permitted to use from paper, a whiteboard, a screen or a PDF. The app detects the chords, you correct and confirm the grid, then the analysis can propose a tonal centre, level-adapted scale material, target notes and a practice routine.
The problem with a chord chart
Every guitarist has been handed the same thing: four bars of symbols. | Dm7 | G7 | Cmaj7 | Cmaj7 |. You can play all three shapes. You still have no idea what to do when it is your turn to solo, which notes make the changes audible, or why your pentatonic box suddenly sounds wrong on the G7.
The chart is primarily a map of the harmony, not a complete map of the guitar. Translating it means identifying the musical context, choosing useful notes and locating them in a playable area of the neck.
How the photo import works
The whole import is three steps, and nothing happens until you ask for it.
1. Send the chart
Upload a clear JPEG or PNG image, or a PDF that you are authorised to use. Printed symbols and legible handwriting give the recognition stage better source material.
2. Confirm the grid
The detected chords appear in an editable grid. You check them, fix anything that was misread, and validate. Editing the grid is always free.
3. Ask for the analysis
You choose when to launch the analysis. The validated grid, selected level and musical context become the input for the generated material.
If you would rather understand the chart yourself before feeding it to anything, start with how to read a chord chart on guitar — the import is faster, but the reading skill is yours forever.
What the analysis actually gives you
This is the honest list — what comes back is built from the chords in your grid, not generic advice pasted from a theory book.
The key centre
A proposed tonal centre when the progression supports one. The field can remain empty when the chart does not establish a reliable global key. See how to find the key of a song.
A scale for your level
One recommended scale or mode, chosen differently for beginner, intermediate and advanced — with the notes to target. More in what scales to play over a progression.
Chord tones and guide tones
Which notes spell each chord, and — when the chart actually contains sevenths — the guide tones that make the changes audible.
Substitutions
Alternative chords to review in context, with a short explanation for each proposal. See chord substitutions on guitar.
A practice plan
A musical goal, a first concrete step, the fretboard zone to work in, a rhythm idea with a counting method, a starting tempo and three exercises.
Practice Cards
Three short cards — chord work, rhythm work, melody/solo — each with what to play, the rhythm, the listening point and a tempo.
The relevant notes can then be examined on the verified fretboard and selected for focused practice.
Why you stay in control
Photo recognition is useful, not infallible. A blurry phone shot of a handwritten chart can misread a Bm7♭5 as a Bm7 — and those are very different chords. That is exactly why the detected grid is editable and why you validate it before anything is analysed.
The same principle runs through the product: the AI proposes, a guitarist decides. If you teach, nothing reaches a student until you have reviewed it — that is the whole point of Teacher Studio.
The same chart, three levels
Hand | Am | F | C | G | to three players and the useful answer is three different answers. That is how the analysis is built.
Beginner
A limited fretboard area, clear chord tones and a manageable scale task without requiring advanced harmonic vocabulary.
Intermediate
Chord tones on the strong beats, arpeggios, and a scale with the context that explains why it fits.
Advanced
Guide tones, tensions, chromatic approaches and proposed substitutions that the player can test against the progression.
The chart never changes. What you are asked to do with it does.
Practical notes: formats and limits
Accepted files are JPEG, PNG and PDF. A few habits make the recognition stage more reliable:
Light it flat
Even light, no shadow across the page, no hard glare on glossy paper.
Shoot square
Straight above the page, chart filling the frame. Skewed angles distort the symbols.
Crop to the chart
Just the grid. Lyrics, tab staves and page furniture only add noise.
AI-import allowances depend on the selected plan and may change as the service evolves. Check the current quotas and included features on the pricing page before importing a new document.
Try it with a chart you already own
Use a chart you are authorised to use and already understand well enough to check. Photograph it, confirm the grid, then examine the proposed tonal centre, scale material, target notes and exercises. This makes the first test concrete while keeping recognition and musical judgment separate.
A teacher normally guides the translation from symbols to playable choices. GuitarHarmonyLab structures part of that work, while the player or teacher validates the result. Berklee’s guide to voice leading for guitar offers an external explanation of how individual notes connect between chords.
