Build Seventh Chords: Mixed Types and Positions

The final review: you are given one note of a seventh chord, with the type and the position chosen at random from the dominant seventh, the half-diminished (leading-tone) seventh and the diminished seventh, in root position and all three inversions. You place the other three notes on the staff.

The three types of seventh chord

TypeSymbolStructure above the root
Dominant seventhV7M3 + P5 + m7
Half-diminished (leading-tone) seventhø7m3 + d5 + m7
Diminished seventh°7m3 + d5 + d7

Each type has its own page where you can practice it separately before mixing them here: dominant seventh, half-diminished seventh and diminished seventh.

Exercise

How to use the exercise: Click (or drag) on the staff to place each note. If a note needs an accidental, choose it first with the accidental buttons (double flat, flat, natural, sharp, double sharp). Undo removes the last note and Clear restarts the exercise. The magnifier shows the note you are about to place at a larger size.

If one of them gives you trouble, practice it on its own first. You can also practice recognizing them instead of writing them.

Frequently Asked Questions

What is a dominant seventh chord?
A dominant seventh chord is built on the fifth degree (the dominant) of a key: a major triad with a minor seventh added on top. It contains a tritone (between the third and the seventh), which makes it sound tense and pull toward the tonic.
What is a half-diminished (leading-tone) seventh chord?
The half-diminished seventh chord, also called the leading-tone seventh chord, is built on the seventh degree (the leading tone) of a major key. It is a diminished triad with a minor seventh (not a diminished one) added on top, so it is not symmetrical like the fully diminished seventh chord.
What is a diminished seventh chord?
The diminished seventh chord is built on the seventh degree of the harmonic minor scale: three minor thirds stacked on top of each other (m3 + d5 + d7 above the root). It is symmetrical, and because its notes repeat every three half steps, it is a favorite chord for modulating.
How do I know which type of chord to draw?
The question always tells you: next to the given note you see the chord type (dominant, half-diminished or diminished) and, if the note is not the root, the inversion in parentheses.
