Minor Six Nine Chord Generator

Minor third with natural six and nine

Cm6/9 contains C, E-flat, G, A and D. The minor third establishes the minor triad while the natural sixth and ninth provide two added tones. There is no seventh. The 6/9 suffix describes additions, not a slash bass.

Minor does not lower every extension. Cm6/9 has A natural, not A-flat. Cm13 contains a flat seventh and more extensions, whereas this five-tone formula contains neither seventh nor eleventh.

• Degree 1 is 0 semitones above the root in this reference.
• Degree 3 is 3 semitones above the root in this reference.
• Degree 5 is 7 semitones above the root in this reference.
• Degree 6 is 9 semitones above the root in this reference.
• Degree 9 is 14 semitones above the root in this reference.

A listening test for m6/9

Compare Cm6/9 with C6/9: only E-flat changes to E. Then compare its displayed notes with Cm9 in the related tool: A is replaced by B-flat. At root D, check D, F, A, B and E; B natural is the sixth above D.

The Compare six nine button retains your chosen root and octave and plays the comparison in root position. Set the current chord to root position for a direct comparison. The note buttons let you isolate the chord member that makes this quality different.

Follow the selected bass through each voicing

This 5-tone reference offers 5 positions. Root position starts with degree 1; First inversion starts with degree 3; Second inversion starts with degree 5; Third inversion starts with degree 6; Fourth inversion starts with degree 9. The bass suffix beneath the chord symbol identifies the actual lowest tone.

Root position preserves compound ninths, elevenths and thirteenths at their original height. The inversion selector first moves the extensions into one octave, sorts by sounding pitch and rotates from the selected degree. These close pitch-class study voicings are different from the complete extended root-position stack; they are not recommended jazz fingerings.

A minor six-nine collection can color a minor tonic while avoiding a seventh. It is compatible with a melodic-minor or Dorian pitch collection at that root, but those shared notes do not by themselves establish a scale or harmonic function.

Check C, F and A before transposing further

Begin with C and confirm C · E♭ · G · A · D. Use the F and A example buttons to transpose the same interval collection. Follow the MIDI values if an enharmonic spelling looks unfamiliar: changing the root shifts every sounding note by the same interval.

Use Root octave 2 for a lower reference or octave 5 for a higher one. A root change keeps your selected voicing; the example buttons return to root position. Reset restores C, octave 3 and root position. Stop sound ends the currently active chord or arpeggio.

What playback and the WAV file contain

The displayed notes are synthesized locally using sine waves after your click. The tool does not create a progression, transcribe a song, provide guitar fingering or simulate an acoustic instrument. No camera, microphone, registration or file upload is needed.

Download WAV saves the currently displayed voicing as a 2.4-second mono PCM file at 44.1 kHz with a short fade. It does not export the comparison chord or an arpeggiated performance. If Web Audio is unavailable, the note display and WAV download remain usable.

Theoretical note names preserve each degree and may use double accidentals. Equal-tempered playback gives enharmonic notes the same frequency. This browser tool does not add new extended-chord gestures to the webcam instrument; that instrument has its own triad, inversion and seventh controls.
