It’s a beautiful song, but you’ll never hear all of it

The first notes in what is going to be a 639-year long piece of music have been played. The composition’s performance actually started 17 months ago, but all that has been heard so far has been the sound of the inflating of the church organ.

The three notes, the first of which was played on Wednsday, will last for a year-and-a-half. The piece is appropriately titled As Slow As Possible.
