For practice and performance I often use custom rubato, or "free play" type custom styles. There is no drum percussion or bass "groove." In many cases I'll activate sync stop, so the sound fades when I lift my fingers from the keys. I suppose it's more like organ playing, except that the arranger still adds a bass note, and I don't have to press all the keys to play a chord. Some of my friends feel that the resulting sound is more authentic, and certainly less busy than full accompaniment. Besides, this is the only way I know of to play liturgical music and traditional hymns.
