Can you recognize these major chords?

About 6 weeks ago I played a recital in my church of organ improvisations with multimedia slides based on selected paintings of my father which coincided with the exhibition "Life - Painting" we put together in the City Hall of Vilnius.

Today I would like to share with you an excerpt of the improvisation on the painting "Saint Michael the Archangel" which was played that evening. I want you to watch this short video with very special intent.

As you listen, take a sheet of paper and try to recognize and write down the names of 25 major chords that I'm playing in this video (the opening chord is E major and the video ends with G major chord).

After you have completed this exercise, here is another video with correct answers provided on the screen, if you want to check your results.

This will be an excellent exercise in ear training.
