The next step after chord shapes
Before this tool, I had already built Chords, Arpeggios, Scales. Its logic is simple: I choose a chord name and get many ways to play it.
For example, I enter Cmaj7 and see different shapes across the fretboard. Then I can choose a comfortable fingering, look at the arpeggio, find a matching scale, and try it in practice.
That is the direct route: from a name to a shape.
But in real playing, you often need the opposite route. I see how someone places their fingers on the fretboard. Or I accidentally find a beautiful voicing. Or I am trying to learn a part from a video. I do not have the chord name. I only have the fingering.
Then the question changes:
These notes sound together. What could this chord be?
That is how the Chord Identifier by Fingering came about.
Why I needed reverse chord lookup
One day I saw a video of a guitarist playing with a looper.
He was not playing regular barre chords. First, he played literally two or three notes on the lower strings higher up the neck. Then he added two or three notes on the higher strings near the beginning of the fretboard. Separately, it almost looked too simple. Together, it sounded like magic.
The harmony felt wider, clearer, and more musical than a full chord played as one dense block.
What caught my attention was not the looper technique itself, but the idea behind the part: you do not have to play a chord all at once. You can split it into voices.
The lower strings give you the bass and the foundation. The higher strings add color. Together, they create the harmony, but it sounds lighter than a thick barre chord.
I wanted to understand how that worked.
The problem: parts like this are hard to hear and name
At first, I tried to simply copy the guitarist.
I watched the hands, tried to figure out which notes he was playing, and moved them to my own fretboard. I wanted to reconstruct the harmony: where the bass was, which upper voices were used, and what chord appeared when all the notes were combined.
But it quickly became clear that the task was not that simple.
To do this confidently, you need several skills at once:
- a good musical ear;
- knowledge of the notes on the fretboard;
- an understanding of intervals;
- an understanding of inversions;
- the ability to see which notes form a chord together;
- enough experience to choose the most likely chord name from several options.
My ear is not as developed as I would like it to be. I also do not always see every note on the fretboard instantly. So I decided to simplify the task.
If I can see which strings and frets the guitarist uses, I can mark those points on a fretboard diagram. Then the tool should calculate the notes and suggest possible chord names.
How the idea works
The logic of the Chord Identifier is simple.
You choose an instrument and tuning, mark a fingering on the fretboard, and the tool shows which notes are sounding and which chords they may form.
This is not magic, and it is not guessing from a picture. It works from facts.
There is a string. There is a fret. There is a tuning. That means the note can be calculated. Once all sounding notes are known, they can be compared with chord formulas: major, minor, sus, dim, aug, seventh chords, added tones, inversions.
The tool does not only answer “this is probably this chord.” It helps you see why it may be that chord: which notes are inside, where the root might be, and which intervals create the structure.
How it differs from the chord shapes tool
Chords, Arpeggios, Scales answers this question:
I know the chord name. How can I play it?
The Chord Identifier answers the reverse question:
I know what I played. What is it called?
Both tools help with fretboard understanding, but they work from opposite directions.
The first tool finds shapes from a name. The second tool finds names from a shape. Together, they close the loop: you can move from theory to the fretboard and back again.
For example:
- You find a beautiful voicing.
- You mark it in the Chord Identifier.
- You get the name and intervals.
- You move to the chord shapes tool.
- You look at other fingerings, arpeggios, and matching scales.
- You return to the fretboard and try to build your own part.
This turns a fingering from a random discovery into musical material you can work with.
How the Fretboard Explorer helped me start building parts
The Fretboard Explorer helped me separately.
Once you start seeing how notes are placed in relation to each other, the fretboard becomes clearer. You do not have to think only in ready-made shapes every time. You can start building voicings yourself.
For example, you can take a bass note on the lower strings, then find a third, seventh, or added tone nearby on the higher strings. You can leave more space between the voices. You do not have to play every chord tone at once. You can split the harmony into several small parts.
And this often sounds better than one dense barre chord.
Of course, there is a separate problem: coming up with a part is one thing, and playing it cleanly and musically is another. I do not always play these ideas as well as I want to. But that is another story. I am working on it.
The important part is that the tool changes the way you think. Not “which shape should I hold,” but “which sounds do I need, and where do they sit comfortably?”
Where this is useful
Learning parts from videos
If you can see which strings and frets a guitarist uses, you can reconstruct the note set and understand what chord appears. This is especially useful when the part does not look like a standard shape from a chord chart.
Naming your own ideas
Sometimes your hand accidentally finds a beautiful grip. It sounds good, but you do not know how to write it down. The Chord Identifier helps give the idea a name so you do not lose it.
Working with inversions
If the bass note is not the root, the chord may feel different. The identifier helps catch these cases and avoid naming the voicing too roughly.
Arranging guitar parts
You can build a chord not as one large block, but as several voices. For example: bass separately, an upper interval separately, and a melody note separately. The Chord Identifier helps check what they form together.
Teaching and learning
For teachers, it is useful to show that a chord is not a picture made of dots. It is a set of sounds. Change one note, and the name, color, and function can change.
Supported instruments and tunings
The Chord Identifier follows the same approach as the Fretboard Explorer.
You can work not only with six-string guitar, but also with bass or ukulele. You can choose the tuning you need. You can view the result as note names or intervals. This matters because the same geometry on the fretboard produces different sounds in different tunings.
If the tuning is wrong, the chord name will also be wrong. So the first step is always the same: choose the real instrument and the real tuning.
How to use the Chord Identifier
1. Choose your instrument and tuning
Start with the context. Guitar, bass, and ukulele are laid out differently. Standard, drop, and alternate tunings also change the note map.
2. Mark the sounding strings and frets
Do not mark everything under your fingers. Mark only what actually sounds. Muted strings should not be included in the chord.
3. Check the notes
First, check the facts: which notes did you get? Even at this step, the sound often becomes easier to understand.
4. Switch to intervals
Intervals show the role of notes inside a possible chord. This makes it easier to see where the third is, whether there is a seventh, and which note creates the color.
5. Compare possible chord names
If there are several options, do not automatically choose the first one. Look at the bass, the key, and the nearby chords. Context often decides which name fits best.
6. Use the result further
After identifying the chord, you can open Chords, Arpeggios, Scales, find other fingerings, explore the arpeggio, or choose a scale to play over it.
A 10-minute exercise
Take one familiar progression, for example Am–F–C–G.
- Play each chord with a regular fingering.
- For each chord, keep only two or three important notes.
- Enter those notes into the Chord Identifier.
- Check whether the original chord remains or whether a different name appears.
- Try moving the upper notes to other strings.
- Check the result again.
- Write one small part where the bass and upper voices sound separately.
The goal is to understand that a chord can be built in pieces. You do not always have to play the full shape.
Common mistakes
Looking for the name only from the finger shape
The shape itself does not guarantee anything. The name depends on the sounding notes and the tuning.
Ignoring the bass
The bass note often changes the feeling of the chord. Sometimes it turns a regular chord into an inversion.
Marking muted strings
If a string does not sound, do not add it to the fingering. Otherwise, the tool will identify a different set of notes.
Expecting one single correct answer
Harmony allows different interpretations. One set of notes may have several names. This is not a tool error; it is a property of musical context.
Not listening to the result
A name is useful, but it does not replace listening. After identifying a chord, play it and check whether it fits the musical task.
What to study next
If you want to see notes and intervals on the fretboard more clearly, open the Fretboard Explorer. It helps you understand how sounds are placed in relation to a selected note.
If you need ready-to-play shapes, arpeggios, and matching scales, use Chords, Arpeggios, Scales.
If you want to understand how a chord works in a key, open Harmony and look at its function inside a progression.
If you are learning chord forms across the neck, it is useful to connect this with CAGED.
FAQ
Can a chord be identified from fingering alone?
Yes, if the correct instrument, tuning, and sounding strings are provided. The fingering becomes a set of notes, and the notes can be used to search for possible chord names.
Why does the tool show several names?
Because the same set of notes can have different interpretations. The bass, key, and nearby chords help choose the most accurate name.
Does it work with alternate tunings?
Yes. But the tuning must be selected before entering the fingering. The same shape can produce a different chord in another tuning.
Can I use it for bass and ukulele?
Yes. The Chord Identifier is not limited to guitar. This is useful if you work with bass parts, ukulele, or alternate setups.
What should I do after I find the chord name?
Check the intervals, listen to the chord in context, find other fingerings, and try using it in a progression or arrangement.
Conclusion
The Chord Identifier is the reverse side of the chord shapes tool.
First, I built the route from name to shape: choose a chord and see how to play it. Then I needed the opposite route: see a shape and understand what is sounding.
This tool is useful not only because it gives you a name quickly. It helps you learn someone else’s part, save your own discovery, see intervals, understand inversions, and start building chords as separate voices.
To try this approach, open the Chord Identifier, mark any interesting fingering, and look at the notes and intervals inside it. It is a simple way to move from “nice shape” to “I understand what is sounding here.”
