Orchestra Performance

My girl is in the percussion group and recently she was involved in an event where she has to perform with her group of university mates.  I did not attend the performance but told my girl to videotape for me to watch.  Yes, I have watched and I am pretty proud of her.  She and her mates have performed tremendously well.  Kudos to them!
Last time I did not know what percussion is but I found out that there are a lot of musical instruments involved and you can find more here at this classic Classroom Tuned Percussion at WWBW.
