In the following exercises you will hear a note and accompanying chord. If you can tell the note and the chord type (major/minor) by ear you can usually figure out what the chord must be.

This is because the melody note is one of the three notes of the chord. So for example if we have a note 2 it must come from chord 5 (572), 7 (724) or 2 (246). As we know from chapter two, the 2 chord is the only one of these three that is minor, so if we hear a minor chord with our note, we know it must be 2.

You need to use your ear to determine the note number, the chord quality (major/minor) and then figure out the chord from the rule.

For example, I hear the note 3 accompanied by a major chord. I know that note 3 is in chords 6, 1 and 3. Chords 6 and 3 are minor, but chord 1 is major, and this must be the chord that accompanies the note.
