Identify Seventh Chords in All Positions

A seventh chord is drawn on the staff, in one of its four positions. Your task is to identify its type: dominant seventh, half-diminished (leading-tone) seventh or diminished seventh.

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

How to recognize each position

Look for the interval of a second among the notes: its position tells you the inversion (between the top two notes: first inversion; between the middle notes: second inversion; between the two lowest notes: third inversion). If there is no second, the chord is in root position. The root is the upper note of the second.

Exercise

How to use the exercise: Choose one of the three possible types and press Check. The app corrects your answer right away and, if you miss, shows the correct one.

Other positions: Root position, First inversion, Second inversion, Third inversion. To practice writing them instead of recognizing them, try building seventh chords. For the full theory, see the pages on the dominant seventh, the half-diminished seventh and the diminished seventh.

Frequently Asked Questions

How do I recognize a dominant seventh chord?
It is built on the fifth degree (the dominant) of a key: a major triad with a minor seventh added. It contains the tritone between its third and its seventh, which makes it sound tense and ready to resolve to the tonic.
How do I recognize a half-diminished seventh chord?
It is built on the seventh degree (the leading tone) of a major key: a diminished triad with a minor seventh added. Because the seventh is minor, not diminished, it is not symmetrical like the diminished seventh chord.
How do I recognize a diminished seventh chord?
It is built on the seventh degree of the harmonic minor scale: three minor thirds stacked (m3 + d5 + d7). It is symmetrical, and its notes repeat every three half steps (UK: semitones), which makes it a favorite chord for modulating.
What do I have to identify in this exercise?
The type of chord (dominant, half-diminished or diminished). The position changes with every question, mixing all four.
