Build and Hear Minor Chords
A minor triad contains a minor third and a perfect fifth. The third is three semitones above the root, one semitone lower than the corresponding major chord. The fifth stays seven semitones above the root.
Start with C: C · E♭ · G. Select another root to transpose the same formula, choose a voicing and press Play chord. Each note also has its own listening button. Audio begins only after a click; there is no camera or microphone request.

The minor formula
A minor triad contains a minor third and a perfect fifth. The third is three semitones above the root, one semitone lower than the corresponding major chord. The fifth stays seven semitones above the root.
The formula 1 · ♭3 · 5 describes intervals from the selected root. The C example is C · E♭ · G; these are 3 separate chord tones. A root change transposes the entire collection, while a voicing change rearranges the same pitch classes.
- Degree 1: 0 semitones above the root.
- Degree 3: 3 semitones above the root.
- Degree 5: 7 semitones above the root.
Locate the lowered third
Listen to A minor and its major comparison. Identify C versus C-sharp while A and E remain unchanged. Then play the notes separately and sing the middle note before hearing the block chord.
The Compare major button keeps the selected root and root octave, and uses the comparison chord in root position. Set this chord to root position too for the clearest quality comparison. Use headphones or a quiet room and keep your listening volume comfortable.
Read the bass before naming an inversion
Root position starts on degree 1. First inversion starts on degree 3; second inversion starts on degree 5. This triad has three positions, so a third inversion is unavailable. The slash label shows the sounding bass and the displayed MIDI values let you verify its pitch.
Inversions preserve the root and quality. This tool raises rotated notes by an octave so the selected bass is the lowest note. For an added ninth, the inversion examples use a close pitch-class voicing; root position retains the compound ninth. These are reference voicings, not the only musical arrangements.
Use A minor, D minor and E minor to compare the same chord quality at different pitches. Inversions change the bass, but they preserve the minor third relative to the root.
Connect the reference to gesture playing
The webcam instrument's minor wrist world changes triad quality. Its degree-to-root mapping remains the major-scale mapping; it is not a natural-minor-scale selector.
The chord laboratory uses buttons and menus for direct note selection. The main gesture instrument uses webcam recognition and has its own supported chord controls. Open that instrument when you want live two-hand performance; the sound and voicing need not match this sine-wave reference exactly.
Spelling, playback and export limits
Changing to a minor chord does not automatically transpose every root into a natural minor scale. Chord quality and the scale used to select roots are separate choices.
Note names preserve the chosen root letter and chord degrees. A sharp, flat or double flat may sound the same as a simpler enharmonic name in equal temperament. The tool keeps the theoretical spelling while MIDI numbers show the actual sounding pitches.
The WAV download is a 2.4-second, mono, 44.1 kHz synthesized chord with a short fade. It contains the currently displayed voicing, not the comparison chord, a melody, a guitar fingering or an automatic chord progression. Stop sound cancels playback; Reset returns to C in octave 3 and root position.
Answers before you play
Minor Chord Questions
What notes are in C minor?
C · E♭ · G. Their semitone offsets from C are 0, 3, 7. The displayed spelling follows the formula 1 · ♭3 · 5.
How is this different from major?
Listen to A minor and its major comparison. Identify C versus C-sharp while A and E remain unchanged. Then play the notes separately and sing the middle note before hearing the block chord. The two generators share playback controls but use different interval formulas and note collections.
Can I use this without a webcam?
Yes. This chord tool needs no camera, microphone or account. The webcam instrument's minor wrist world changes triad quality. Its degree-to-root mapping remains the major-scale mapping; it is not a natural-minor-scale selector.
Why is an enharmonic note spelled with a sharp or flat?
Chord degrees determine note letters. A theoretically correct spelling may include two accidentals even when a simpler name has the same MIDI pitch. Playback uses equal temperament at A4 = 440 Hz.
What can I do if sound is unavailable?
Check the tab's sound setting and your output device, then press Play chord again. The notes and local WAV download work independently of real-time playback. The page reports a Web Audio error rather than requesting microphone access.
