Recognise progressions (in many keys)

Identify the chords of a progression, now in many keys, not just C.

1. Step 1A chord progression will appear: identify each chord in the sequence, looking at it as a group of voices, not a block.
2. Step 2The progression can now be in any of the twelve keys, not just C: pay attention to the root of each chord.
3. Step 3For each change, follow the common tones and the stepwise voice motion until you recognise the progression confidently.
