The trailer was this one:
Did you catch it?
It's only brief, about 30 seconds at most. It is "Speigel im Spiegel", by Arvo Pärt. Here's the full version:
It's a beautiful piece of music. I love it, I love the image it creates in my mind of a calm and peaceful place where I am safe and secure, where I can rest and relax and let any and all worries leave my mind. And every time I listen - every single time - I will well up and I may well cry. If I'm alone, I'll probably let it out, but if I'm in company I will probably just go quiet and maybe a little distant. It has done that to me ever since maternal grandmother left this world over ten years ago, because every time I hear it, it reminds me of her.
I have no idea why. We never listened to it together, I have no idea whether she ever even heard it. She wasn't especially into music, but the little music she did have was very, very different. There is no logic as to why it should be this piece in particular, but it is so, nevertheless.
There's another piece of music that does this to me. It's in a rather different style, and a little more recent. Pärt's piece is moderately highbrow, this very definitely isn't - it is simple, straightforward, and commercial. It's this:
This one reminds me of Mum. The link here is even more tenuous - she cannot possibly have heard it, as it was released after she died. Common sense says the song can have no connection with her, but my own personal logic has connected them; every time I hear it, she is in my mind, and I am back there with her on her sofa in the last few weeks, with her (exhausted) sleeping against my shoulder with my arm around her.
Nothing triggers my memories of these two wonderful, strong women with the intensity of these pieces of music. I want to hate them both for the effect they have on me, but I can't.
I love both pieces. I love them for the connection they give me.
