A well played organ is an incredible thing to hear. In college one of our professors had received his Doctorate in organ and was amazing. There are those who view it as an ancient instrument that is out of date, but these people do not realize what they are missing. In college we had mandatory chapel, but the minute it was over everyone scattered. Yet I remember one time when he began to play the organ for the postlude and almost no one moved.  They sat their and listened to the entire piece. The music filled the room in a way that no electric instrument could. And to sing a piece of music accompanied by an organ is beyond compare the blending of a human voice with the organ is unmatched. It is sad to realize how much people today do not understand its beauty. I remember one day standing at the back of the chapel, during some remodeling, speaking with a student.  The student expressed how he thought the organ should go as well because is was dated and no longer fit in. I was appalled at the thought.  Thankfully, wiser minds won out and the organ remains to this day. Yes organs have been sadly silenced in recent year, but there is still a place for them.  Some great point are made for keeping the organs in the blog:
