SWARSHALA — SEVENTH-CHORD WORKSHEET
Original learning aid, 3 October 2026.
Guide: https://swarshala.com/blog/build-and-compare-seventh-chords
For each chord, record root / letter frame / lower triad quality / root-to-seventh quality / complete spelling.

SELECTED CONVENTIONS
maj7:major triad + major seventh.
7:major triad + minor seventh.
m7:minor triad + minor seventh.
ø7:half-diminished, diminished triad + minor seventh.
°7:fully diminished, diminished triad + diminished seventh.
These are five common qualities, not every possible seventh chord.

QUESTIONS
1. G frame G–B–D–F: build all five qualities.
2. D frame D–F–A–C: build Dmaj7, D7, Dm7.
3. B frame B–D–F–A: build Bø7 and B°7.
4. Name C–E–G–B-flat and C–E–G–B.
5. Repair C–E-flat–G-flat–A as C°7 without changing equal-tempered pitch.
6. From F7 alone, distinguish what is known about quality from what is unknown about function.

ANSWER KEY
1:Gmaj7 G B D F-sharp; G7 G B D F; Gm7 G B-flat D F; Gø7 G B-flat D-flat F; G°7 G B-flat D-flat F-flat.
Root distances respectively:0,4,7,11 / 0,4,7,10 / 0,3,7,10 / 0,3,6,10 / 0,3,6,9.
2:Dmaj7 D F-sharp A C-sharp; D7 D F-sharp A C; Dm7 D F A C.
3:Bø7 B D F A; B°7 B D F A-flat.
4:C7 and Cmaj7.
5:C E-flat G-flat B-double-flat; B is the seventh letter.
6:F A C E-flat, dominant-seventh quality. Harmonic function in a particular key requires context and is not settled by the symbol alone.
