Identify Seventh Chords in Root Position

A seventh chord is drawn on the staff, in root position. 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 root position

In root position the four notes are three thirds stacked on top of each other, and the bass is the root. Read the intervals above the bass to find the type.

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 is fixed: always root position.
