The theme of Tchaikovskys 5th symphony is defined by the first eight bars of the score; forty five seconds, a few notes on a page are the foundation for nearly fifty minutes of music. The theme of the piece is played again and again but each time slightly transformed. A bit quicker now then slower, a crescendo then a whisper. Sometimes the clarinet takes the lead then the whole ban will play in unison. One player will start, and before he has come to the end, it will be picked up by another. There is movement in time, a transformation or physical displacement. A rethinking of the one becomes many. Repeated, but not identical. The present act resulting from the one that came before.
