Seventh Suspended Second Chord Generator

Replace the third with a second and keep the flat seventh

C7sus2 contains C, D, G and B-flat. D takes the place of E; the major third is absent. The flat seventh remains, so this is a four-tone suspended seventh rather than the three-tone Csus2 triad.

C9 includes both E and an upper D, whereas C7sus2 replaces E with D. The complete collection here does not contain a hidden third. Moving D up an octave changes spacing but does not add the missing E.

• Degree 1 is 0 semitones above the root in this reference.
• Degree 2 is 2 semitones above the root in this reference.
• Degree 5 is 7 semitones above the root in this reference.
• Degree 7 is 10 semitones above the root in this reference.

A listening test for 7sus2

Compare C7sus2 with C7. D changes to E while C, G and B-flat stay the same. Play the D button and then the C button to hear the suspended second against the root. With root F, verify F, G, C and E-flat.

The Compare dominant seventh 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 4-tone reference offers 4 positions. Root position starts with degree 1; First inversion starts with degree 2; Second inversion starts with degree 5; Third inversion starts with degree 7. The bass suffix beneath the chord symbol identifies the actual lowest tone.

Changing voicing raises the notes before the selected bass by an octave. The pitch classes and chord quality remain the same; only the register and bass change.

Use the suspended-second reference to test a third-free accompaniment under a melody. D may move to E or remain as a stable color; the word suspended in a chord symbol does not require a particular resolution or a prepared classical suspension.

Check C, F and A before transposing further

Begin with C and confirm C · D · G · B♭. 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.
