playing without any style on the organ, I find you can give more of your own feelings into expressing it
.. particularly when it is a 'classical' piece being played. 'Expression' is not just 'loud' and 'soft', but 'fast' and 'slow' as well. You can do the 'loud' and 'soft' bit, but not the 'fast' and 'slow' if you are using a Style and have the rhythm going.
For those classical 'purists' amongst you this next piece is not going to do any 'wows' for you. One can ask the question, what is it that makes a piece 'classical'? Is it the melody, or the way it is played? Both, I fancy. But I remember the series called "Hooked on Classics" done by Louis Clark and the London Philharmonic Orchestra. I was hooked on that. So here is my 'classical piece' as a 'not so classical' piece.
Ave Maria (Schubert)

The 'arpeggio backing' in the Style is one I have put in myself (ie. it's not one of the PARTS in the original AR Style).
