You can click on the 'Play Progression' button to hear what the progression sounds like. The Roman Numeral is shown underneath each chord to show you how it relates to the key. The Tonic chord is shown in yellow to draw your attention to it. The Dominant chord is in green and the sub-Dominant in Blue.
