Tinkling the ivories

I don't really have any piano playing skills, but Davie lent me this keyboard so that I could experiment on it. I picked out three notes which sounded good, a bit like film music, then I did the same, again, but a semitone down. I then found the chords; E minor and Am, as it turns out, on my guitar. There could be a song in this, but I'm not sure. I then knocked over my guitar, which somewhat destroyed the spell.
