Video of LR sequence in Beethoven's Ninth Symphony

Video of the succession of chords in Beethoven's Ninth Symphony:

Use the spacebar, or the Play/Pause icons, to check the chord sequence (C --> a --> F --> ... --> A). In this view of the Tonnetz, a major chord points upward with its root on the bottom left, while a minor chord points downward with its root chord on the top left. For more discussion of how the Tonnetz is displayed in this video, go to here.
