Key changes in Un Sospiro

[threepwood]

Hello everyone,
I'm trying to analyze the key changes in Listz's Un Sospiro, but I find it a bit challenging. A swift google search doesn't seem to give me any convincing answers, so I was wondering if there's anyone here who really knows music theory and the piece? This is my own attempt:

Starts in Db major, and then:
Shift to A major (around 1:10)
Shift to F minor (around 1:45)
Shift to F major (around 2:00)
Shift to E major (around 2:15)
Back to Db major (around 3:40)

Thanks,

I overall agree with your analysis, but I'd switch E major with C sharp minor, since he is hovering around its dominant chord (G sharp major) a lot, among many reasons. What's making you doubt your analysis?

Hey lelle, thanks for your input.
I can see that you're probably right about the C# minor part. I just felt a bit unsure about the F minor part, and then there's the part around 3:00 with the F7-Am/E-D chord progression, where it also sounds to me like it's changing key for a second. But maybe I should just ignore that.

What makes you unsure? Asking in the interest of challenging your brain I see a pretty neat modulation from A major to F minor, ending with a D64-53 cadence, but then he launches into the F major section basically like a Picardy third.

He does some cool harmonic progressions that basically lead back to where he started occasionally. Could you maybe post a screenshot of the passage just so I can be sure what you are talking about? The recordings I'm referencing have different timings than yours

Okay, so, how I decide this, is basically by determining the key for which it sounds natural for the piece to end on (which might be a total newb approach compared to you). So in the F minor part I was a bit unsure, because it could just as well end on F major there, but I ended up going with F minor because there is an F minor there in that part.

I would get familiar with what the Tonic, Dominant and Subdominant is, and how they typically are used in classical music. There are a couple of very common chord sequences (cadences) that, once you are familiar with them, can help you identify the current tonal centre in a large quantity of pieces and passages.

There is of course more to it but that's a good start.
