Wrong guess.
It wasn't Star Wars. Instead, my brothers and sister ordered the piano tuner. Which was a good idea – last time our piano was tuned was, according to the guy's records, back in 1998. My brother was still attending piano classes back then, and my parents made sure the piano was more or less tuned correctly most of the time.
Since he stopped those classes a few years back, the piano just stood there. We didn't get rid of it, and I liked to play it every once in a while. Not that I'm extremely good at it, but, well.
I started playing more often lately, since I've discovered the existance of the Mutopia Project. I guess they noticed; and since my now 24-year-old brother has been playing the guitar since he was 10, or so, I guess he got quite irritated with me playing on a piano so direly in need of tuning...
Heh. Well, it does sound a lot better now. Thanks
