Question 1

How does the exercise work?

Accepted Answer

A chord progression plays in a loop. Listen carefully, then select the Roman numeral pattern that matches what you heard from the four choices.

Question 2

What do the difficulty levels change?

Accepted Answer

Higher difficulty levels add more complex progressions - from simple pop (I–V–vi–IV) at D1 through jazz and borrowed chords at D4, up to 8-chord phrases at D5.

Question 3

What are the key and style options?

Accepted Answer

You can keep every progression in C for easier practice (C major, or C minor for a minor progression), choose a random key, or hear a random key with its name shown. The style option switches between block chords, arpeggios, and a strummed feel.
