I have been interested for quite some time in the harmonic progression in Brangane's warnings in the second act of Wagner's Tristan und Isolde. My question: how can one analyze the chord progression in this passage ?
Here's the link for the Brangane's first warning on Youtube. After a bit of time, here's what I have found:
- From 0:00 to 0:34 in this link, I have difficulties identifying the chords. It does not seem to be triadic harmony, but instead tetrachords.
- From 0:34 to 01:22, it seems easier. I have found the following chord progression: D, A, G, C#, Am, Em, C#m, Eb.
I am not used to analysis, and as such I don't know how to proceed with this progression, for which I see no apparent pattern. I have studied transformational music theory for some time, and I have written the transformations from one chord to the other using both the transformation/inversion (T/I) group, and the PLR group, but there does not seem to be any significant pattern here as well.
Any help would be appreciated...
