Seventh Chords Ear Training

Learning Goal: To recognize the sound-feeling of the five most commonly-used 7th chords: major, minor, dominant, diminished, and half-diminished…

Format: Downloadable MP3s that allow you to do ear training for the five main 7th chord types almost anytime and anywhere: while doing the dishes, taking a walk, or driving your car!

Important Note from Frank: Don’t get too carried away with this. Do just enough to get the gist for how each 7th chord type sounds and feels. You will get lots more experience when we study 7th chords as part of chord progressions in real music.


Ear Training Files: Seventh Chords (MP3s)

This downloadable study consists of dozens of MP3s compressed into a single *.zip file. Simply download, unzip, create a playlist, set to random play, and do ear training on the run!

Each mp3 follows the same sequence:

  1. A random 7th chord is played.
  2. Identify it by type: major, minor, diminished, dominant, half-diminished.
  3. After a short pause, the correct answer is given.

Listen to an example:



Successful ear training is not the fruit of trying to hear something. It is about being receptive to the sound/feeling you are experiencing and then associating that sound/feeling with something you already know–in this case the name of each 7th chord.
