Interessant - wo hast du das denn so (mit Apostroph) gelesen?

Das ist (genau*) das, was mich schon immer interessiert/fasziniert hat.

* das "genau" steht das so nicht im Satz, hier nur zur Verdeutlichung ...

#2: Out of interest: If you were going for an apostrophe, why did you use an acute accent?

As for the meaning of "That gets me", it does not mean "interessieren" or "faszinieren" in this context. It's about the emotional effect.

#4: Out of interest: If you were going for #1, why did you use #2?

:)

Woody 1 just copied it from the OP.

I don't know. I think this "gets me" can be interpreted in different ways. The "changes" mentioned here most likely are referring to chord progressions in the music. That's the word often used by jazz musicians, ie. "chord changes". The well known 12-bar blues is extremely primitive harmonically, it couldn't be simpler. And yet, the wealth and depth of feeling that can be expressed with "these simple changes" is truly amazing. And that's what "gets him". That's my take on it. Maybe more context would confirm my theory; or maybe I'm off base here.

So I think "faszinieren" comes close, or maybe "verblüffen"?

Because it doesn't make sense with what comes directly before. At least not with my understanding of "simple changes" and I can't think of any other meaning for "simple changes" here. That's why I asked what you thought it meant.

Look at the the context given:

"You have to bring the feeling and expression to it. What can you emote with these simple changes? That’s what always got me."

If the sentences were: There's so much feeling and expression in the blues. That's what always got me.

...then Pipper's interpretation would make sense. But the context given is different.

"Emote" is also an interesting choice of words BTW. He frames it as a question, but it's a rhetorical one.

He could just as well have answered:

Look at the incredible wealth of emotions that can be expressed by these simple technical means. That's what always got me.

@#11: ...and referring to chord progressions which grab you / touch you.

I don't see that anywhere.

changes --> chord changes --> chord progressions

and your 'wealth of emotions'

Nicht die Akkorde berühren ihn, sondern es fasziniert/verblüfft ihn, welche Palette an Gefühlen man mittels einfacher Wechsel ausdrücken oder erwecken kann.

Vorschlag:

Welche Emotionen kann man mittels dieser einfachen Akkordwechsel ausdrücken? Das hat mich schon immer gefesselt.

Edit: ähnlich wie Braunbärins #8
