These are all very unique from each other!
I've only really listened to Bach this week because of the Google Doodle featuring him.
However, I think it's really fascinating that Bach was definitely a devout worshiper of God and seems to have had a personal relationship with Jesus. He studied the works of Martin Luther, whose hymns also played a part in some of his own compositions, and also studied the historical accounts of Josephus... Bach ended all his works with Soli Deo Gloria or "To God alone be the glory".
He's the first composer Google chose to try out their AI music technology. So it's all really amazing to think about the continued influence that worshiper of God has had through simply writing music to glorify Him! Talk about leaving a legacy and a branch that bore good fruit...
Here is my favorite of his works. Ironically, I became familiar with this one from an old 1980's computer game called "Big Mac"! So I included a video for that too.
