OK. So I read this thread about which instrument was the hardest to play. Many though flute and tuba, and many said guitar, violin or piano. And the truth is, the hardest in fact is the king of all instruments as stated by W.A. Mozart, the organ. Think about it, two or more keyboards to control with your hands, and a keyboard at your feet. Not only to you have that to think about, but also the registration, meaning which stop combinations to use. Not only that, but pipe organs in themselves are very hard to play because of the resistance in the keys according to how many stops you have pulled out. When you pull out a stop, every time you press down a key, you are pulling back a piece of wood from underneath the pipe to allow wind to pass through it to make a sound. So the more stops you pull out on a single keyboard result in more wood being held back, meaning more pressure is needed to actually push down the key. So just think about that. It is a lot to think about, and believe me, as an organist, sometimes it is enough to make you want to drop the whole thing all together. So I just thought I would bring that up. Because I think it is a really sad thing to know that the organ doesn't get the respect it use to have. Now the organ has been reduced to people solely thinking about an old lady at church playing hymns, or the Phantom of the Opera. Thanks, and check out youtube. There are many great videos that show the versatility of the monster instrument. Try searching Widor Toccata, or Wedge Fugue. Both are great.
