Introduction
Knowing a chord name is not enough. In practice, you usually need answers to other questions: where to find a comfortable fingering, which notes are inside the chord, how to play its arpeggio, and which scale to use over it.
You can work all of that out by hand: write out the notes, count the intervals, search for shapes on the fretboard. But that takes time. By the time you get to the instrument, your attention is already stuck in calculations.
The Chords, Arpeggios, and Scales tool in Six Strings App makes this easier. It helps you do more than just find a chord. You can also see its note structure, its arpeggio, and the scales that fit it. As a result, theory turns into sound faster instead of staying a collection of diagrams.
This tool is actually where the whole site began. I originally built it for myself because I wanted to better understand chord construction, see chord arpeggios across the fretboard, and figure out which scales truly fit a specific chord. Once I managed to bring all of that together in one place, the rest of Six Strings App gradually grew from that idea.
In this article, we’ll look at who this tool is for, what musical problems it solves, and how to use it in real practice.
What this tool does
This is an online tool for guitar, bass, and ukulele. It shows chord fingerings, arpeggios across the fretboard, and scales that match the selected chord.
Its main strength is the way it connects things. You see more than a chord shape. You also see its interval structure, its target notes, and the melodic material you can build from it. That makes it useful for practice, song analysis, improvisation, and songwriting.
Who it is especially useful for
Beginners
Beginners often memorize chords as pictures. Because of that, theory and the fretboard stay separate. This tool helps connect them by showing that a chord is not just a grip — it is a set of notes with a clear musical function.
Players who want to understand the fretboard better
If you already know the basic shapes but keep moving through the same box patterns, this tool helps you get past those привычные схемы. You start seeing the chord more broadly: as a shape, as an arpeggio, and as the basis for melody.
Teachers
This tool is convenient for teaching. It is much easier to show a student intervals, arpeggios, and the relationship between a chord and a scale when everything is in one place and visible on the fretboard.
Songwriters and composers
When you write music, it helps to test ideas quickly. Here you can find a chord shape, look at its notes, choose a scale, and immediately understand what you can build from it: a riff, a melody, or a solo.
What musical problems it solves
Finding the right fingering quickly
The same chord can be played in different ways. One shape may work for accompaniment, another for tighter voice leading, and another in a higher register. When the options are collected in one place, it is easier to choose not just the first fingering you see, but the one that fits the actual musical job.
Understanding chord structure
Many players can play chords but do not always know where the root, third, fifth, seventh, or added tones are inside them. Without that, it is harder to analyze harmony and build phrases with intention.
When you see not only the notes but also the intervals, the chord stops being just a picture for your fingers. It becomes a clear musical structure.
Moving from a chord to its arpeggio
An arpeggio is the most direct bridge between a chord and a solo. It helps you hear the target notes and land on the harmony instead of guessing.
When the chord and its arpeggio are visible side by side, the connection becomes obvious. You are not learning separate material “just in case.” You immediately understand how to use it in phrasing and improvisation.
Choosing a scale for a chord
Almost everyone runs into the question: “What do I play over this chord?” The usual problem goes in one of two directions: either the player uses the same familiar scale everywhere, or they get lost in theory and cannot quickly choose a practical option.
This tool shortens that path. It shows scales that fit the chord and gives you a starting point. From there, you can listen, compare, and decide which color works in your musical context.
How to use this tool in practice
For daily practice
Take one chord and break it down in four steps:
- look at several fingerings;
- find the intervals inside the shape;
- play the arpeggio;
- try one of the suggested scales.
This short cycle gives you more than mechanically memorizing new diagrams. You train your hands, your ears, and your understanding of the fretboard at the same time.
For analyzing songs
When you break down someone else’s music, it helps to understand not only the chord name but also its function. This tool lets you quickly inspect the chord structure, see the arpeggio, and check which scales naturally sit on top of it.
That is especially useful in parts that seem simple on the surface but get their character from added tones, bass movement, or modal color.
For improvisation
If you want to spend less time running box patterns and hear the harmony more clearly, build your lines from chords. First find the target notes in the arpeggio, then expand them with a scale.
This approach makes your solos feel more focused. You are not just moving through a shape — you understand why each note sounds stable or tense.
For writing riffs and chord progressions
This tool is useful for creative work too. You can start with a chord, look at its notes, and build a riff from them. Or you can go the other way: choose a scale and see which chords and melodic ideas naturally grow out of it.
That speeds up the search for ideas and makes it more intentional.
For teaching
When theory is shown directly on the fretboard, students understand it faster. They do not need to look at a notebook, then a diagram, then the instrument. Everything is already in one context.
That is why this tool works well for homework, breakdowns, and explaining the core relationships between chords, arpeggios, and scales.
Why this is especially useful inside Six Strings App
This tool has a practical advantage: it is not limited to just chords or just scales. Everything is gathered into one system.
What that gives you:
- support for guitar, bass, and ukulele;
- support for different tunings;
- display of notes or intervals;
- arpeggios across the fretboard;
- matching scales for a chord;
- a left-handed mode.
Because of that, the tool works not as a one-off reference page, but as a reliable working point in regular practice.
How to get started
The easiest way is not to try to cover everything at once.
Pick one familiar chord. Look at 2–3 fingerings. Then switch on interval view and find the target tones. After that, play the arpeggio and try a few short phrases using one of the suggested scales.
That alone is enough to feel the main idea: a chord, its arpeggio, and its scale are not three separate topics, but one connected musical system.
FAQ
What is the main point of this tool?
It helps you do more than just find a chord. It helps you understand how the chord is built and what to do with it next: how to play its arpeggio and which scale to try over it.
Is it suitable for beginners?
Yes. Especially if you want to do more than memorize shapes and actually understand which notes inside them are doing the work.
Is it only for guitar?
No. The tool supports guitar, bass, and ukulele.
Why look at intervals if I can already see the notes?
Notes show you the actual pitches. Intervals show you their function. For improvisation, analysis, and harmonic understanding, that is often more useful.
How is an arpeggio different from a chord?
A chord is a group of notes played together. An arpeggio is the same notes played one after another. In solos and melodic phrases, arpeggios help you lock into the harmony more precisely.
Does the tool choose the perfect scale?
No. It shows practical options. The final choice depends on the key, the harmony, the style, and the sound you want.
Can I use it for writing music?
Yes. The tool works both for practice and for real writing: riffs, melodies, solos, and chord progressions.
Conclusion
Chords, Arpeggios, and Scales is not a tool about collecting diagrams. It is about the connection between a chord shape, its notes, and its musical use.
It helps you navigate the fretboard faster, understand harmony better, and use chord-based material in practice, improvisation, and songwriting.
If you want to see notes and sounds across the fretboard even more clearly, the next step is Fretboard Explorer. If you want to understand how a chord works inside a key, move on to Harmony.
