drill: chord functions: eMusicTheory.com

Instructions

Click "Settings..." to change the way the drill works — you can control which chord functions you'll be asked (see the groups listed below), in which keys, and if sounds will play.
Click "Start Drill" to see your first question.
You'll see a blank staff, and the name of a chord function. You'll hear a basic IV V I chord progression to establish the key, then the chord you'll need to build.
Add in the notes to make the chord one at a time, by clicking on the note button you need, then clicking on the staff.
If you get it right, you'll get another chord to build. If you try adding a wrong note the drill will "shake", and you can try again.
Hints: you can click "Play chord" to hear the chord, or "Give up" to see the answer and go on to the next question.
When you're done working, click "Stop Drill".

You can quickly choose the note you need using the keys 1-5:
1 = double-flat, 2 = flat, 3 = natural, 4 = sharp, 5 = double-sharp.
