The obvious technical difficulty in Bach could be one reason to study his music, and many people (like my Mum) find listening to Bach's keyboard works to be a rather boring affair. However, I think that as someone who has played Bach, the technical difficulty is something which is to be overcome as with any piece of music, and only when you can play a fugue blindfolded will the true emotion and spirit of the music begin to affect you.

This is why I found starting to play Bach so very boring. It wasn't until I had arduously learnt a piece that I understood that this music is truly greater than the sum of its parts. The intertwining lines appear at first to be rather sterile, but the combination of them and the feeling of playing them as a whole rather than separately is quite indescribable.
