Build and Listen to Seventh Suspended Fourth Chords
C7sus4 replaces the E of C7 with F. The exact collection is C, F, G and B-flat. Keeping the flat seventh separates it from the plain Csus4 triad. This reference omits the third entirely.
Compare C7sus4 with C7 to hear F move down to E. Isolate F and B-flat as the fourth and flat seventh. Try G7sus4: G, C, D and F. A move from C to B would resolve the suspended fourth in that root.

A fourth in place of the dominant third
C7sus4 replaces the E of C7 with F. The exact collection is C, F, G and B-flat. Keeping the flat seventh separates it from the plain Csus4 triad. This reference omits the third entirely.
C11 can retain E in its complete formula, while this C7sus4 has no E. A simple sus symbol normally refers to sus4, but sus2 is a different collection and has its own page. The generator states the fourth explicitly.
- Degree 1 is 0 semitones above the root in this reference.
- Degree 4 is 5 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 7sus4
Compare C7sus4 with C7 to hear F move down to E. Isolate F and B-flat as the fourth and flat seventh. Try G7sus4: G, C, D and F. A move from C to B would resolve the suspended fourth in that root.
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 4; 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.
A suspended seventh can delay a dominant third or work as a stable third-free color. The single-chord tool shows the ingredients; use the compare playback to hear one possible resolution without assuming that every sus chord must resolve.
Check C, F and A before transposing further
Begin with C and confirm C · F · 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.

Seventh Suspended Fourth Chord Questions
What are the notes in C seventh suspended fourth?
C · F · G · B♭. The formula is 1 · 4 · 5 · ♭7, with semitone offsets 0, 5, 7, 10. These are the complete notes sounded by this generator in root position.
How does this differ from dominant seventh?
Compare C7sus4 with C7 to hear F move down to E. Isolate F and B-flat as the fourth and flat seventh. Try G7sus4: G, C, D and F. A move from C to B would resolve the suspended fourth in that root.
Are these standard performance voicings?
A suspended seventh can delay a dominant third or work as a stable third-free color. The single-chord tool shows the ingredients; use the compare playback to hear one possible resolution without assuming that every sus chord must resolve. The tool states its complete formula and uses close pitch-class rotations for inversion study. Performance omissions and spacing depend on the instrument and musical context.
Can I play and export without a camera?
Yes. Click Play chord or Play arpeggio for local audio. Download WAV saves the displayed chord even if live audio is unavailable. Camera and microphone permission are never requested.
Why does the displayed accidental look unusual?
C11 can retain E in its complete formula, while this C7sus4 has no E. A simple sus symbol normally refers to sus4, but sus2 is a different collection and has its own page. The generator states the fourth explicitly. Note letters follow chord degrees; MIDI numbers show the actual pitches at A4 = 440 Hz.
