Jacob Collier discusses various music theory concepts in a Q&A format. He explains the difference between pitch and timbre, demonstrates reharmonization with "Hey Jude," clarifies the concept of the tritone and its historical context, and answers questions about piano pedals, time signatures, key characteristics, and the circle of fifths. He encourages exploration in music theory but also emphasizes that nothing really matters except enjoying the process of making music. Jacob ends by inviting more questions for future discussions.
