Introduction

Chordopia is a chord finder app for guitar, ukulele, and mandolin. You can enter the name of a chord, and Chordopia will show you many different ways to play it (known as voicings). It also works the other way around: you can enter a voicing by dragging dots on a virtual fretboard, and Chordopia will tell you what chord that plays.

Finding Voicings for a Chord

To find voicings for a chord, select the chord using the chord picker:

The lefthand column selects the chord root, the middle column selects the chord type (major, minor, 7th, etc), and the righthand column lets you specify the bass note of the chord.

The first entry in the middle column is blank and stands for a major chord. The first entry in the righthand column is also blank, and means the bass can be any of the notes in the chord.

The fretboard display will show you the first of many voicings for the chord.

Swipe left on the fretboard to see alternative voicings.

Finding Chords for a Voicing

To go the other way and find the chord that a given voicing plays, enter the voicing by dragging the the finger dots on the fretboard vertically. If there are O:es or X:s at the top of the fretboard, indicating open or muted strings, they can also be dragged to the fretboard or back. To turn an X into an O or vice versa, just tap on it.

To enter a barre chord, drag more than one dot to the same fret, and the barre is recognized automatically. To reach frets not visible on the screen, you can drag a finger dot below the bottom or above the top of the fretboard. This will cause the fretboard to start scrolling vertically. The scrolling stops when the dot is moved back to inside the fretboard.

If you already know a chord that is similar to the one you want, for example another barre chord on the same fret, it can be faster to start by selecting that chord in the chord picker and then just drag the dots for the fingers that are different.

The chords that match the voicing you entered will be shown in a list that appears in place of the chord picker:

Often the same voicing matches more than one chord; for example, Esus4, Asus2, and a B11 chord with the 5th and 9th degree omitted all contain the same notes, so if you select a voicing for one of the three, all three chords will be shown in the list. Tapping one of the chords in the list takes you back to the chord-to-voicing mode and selects that chord in the chord picker.

If the voicing you entered does not match any chord, the message Not a known chord is displayed. You can tap on the message to return to the previous chord, or continue dragging dots until you find a voicing that corresponds to a known chord.

Playing Sound

Tapping the speaker button plays the current chord through the speaker or headphones, using the current voicing. If you would like to play sound automatically every time you select a new chord or voicing, turn on the Auto Play switch under Settings .

Saving Favorite Voicings

If your favorite voicing for some chord is not the first one shown, swipe left on the fretboard until you find it, and then tap the Favorite button . This marks the voicing as a favorite, and the next time you search for the chord, that voicing will be shown first. To undo this, just tap again.

Navigating the App

The Info page

Tapping the Info button brings up the Info page, which contains links to documentation along with lists of chords related to the currently selected chord:

Same Notes
Other chords containing the same notes as the selected chord, possibly after omitting some non-essential notes.
Fewer Notes
Other chords containing some, but not all, of the notes in the selected chord.

Settings

Tapping the Settings button opens the Settings page, where you can adjust various settings according to your preferences. The Settings page is divided into the following sections:

Display Settings

Here you can customize the display of chords and notes:

Note names

You can choose between two different conventions for naming the notes in the C-major scale. In English-speaking countries, they are usually called C D E F G A B, but in Germany and a few other countries they are called C D E F G A H, and B is the semitone between A and H.

Semitone display

You can choose whether chromatic notes should be shown using sharps () or flats ().

Chord symbol style

Selects the style in which chord names are displayed:

Pop / Rock
The Pop / Rock style uses mixed case and abbreviations, like Cmaj7. Diminished seventh chords are denoted by dim, and augmented chords by aug.
Jazz
The Jazz style is based on Standardized Chord Symbol Notation, a Uniform System for the Music Profession by Brandt and Roemer. This style uses uppercase text and subscript and superscript notation, like CMA7. Diminished seventh chords are denoted by a ring symbol, and augmented chords by a plus sign.

Instrument Settings

The Instrument sections contains settings related to your musical instrument:

Instrument type

The type of instrument you want to find chords for. The supported instrument types are guitar, ukulele, and mandolin.

Tuning

How your instrument is tuned. For each instrument type, there is one or more pre-defined tunings, and the last entry lets you define a custom tuning. When the custom tuning is selected, the pitch of each string can be adjusted in steps of one semitone by pressing the + and buttons.

Sound

If you have selected Guitar as the instrument type, you can choose between several different guitar sounds for playing back the chords: a Nylon Acoustic, Steel Acoustic, Clean Electric, or Distortion Electric guitar. For the ukulele and mandolin, only a single sound per instrument is available.

Number of frets

Set this to the number of frets of your instrument, or if you never use the highest frets, you can set it to the number of frets you actually want to use so that Chordopia won't show voicings using those frets.

Preferred neck position

By default, Chordopia prefers voicings where the strings are fretted near the saddle, on low-numbered frets. If you like to play higher up on the neck, you can change this setting to a fret number of your choice, and Chordopia will list voicings near that fret first.

Sound Settings

The Sound section contains sound settings common to all instruments:
Auto play

When the Auto play switch is turned on, any time a new chord or voicing is selected, it is immediately played through the speaker or headphones. When off, you need to tap the speaker button to play them.

Strum speed

The Strum speed slider determines how fast the chords are strummed. Moving the slider to the left makes the strumming slower, moving it to the right makes it faster.

Limitations

Chordopia's knowledge of the anatomy of the human left hand is limited, and some of the voicings it finds may turn out to be difficult or impossible to finger in practice.

Alternate bass is supported only when searching for voicings for a chord, not when finding chords for a voicing.

Tips and Tricks

The note played by each string is displayed below the string. If you tap in this area, the display alternates between note names and scale degrees. For example, the notes in a C7 chord will be shown either as C E G B or as 1 3 5 7, identifying the notes as the root, third, fifth, and minor (flat) seventh. The latter display is only available when a chord has been selected by name, not when a voicing has been selected by dragging the dots.

When scrolling through the voicings, you can quickly return to the first one by double-tapping the left arrow to the left of the fretboard. As you might expect, double-tapping the right arrow also works for jumping to the last voicing, but this is not particularly useful because the voicing listed last is usually one of the worst.

If you play with a capo, you can take it into account by setting up a custom tuning where every string is raised by he same number of semitones.
