Hey guys, I'm new here...thought I would ask a question.

I've been playing classical piano for the past 7-8 years or so, and over the years I've learned near all of music theory...but I'm trying to pick out some unique patterns for my scale climbs/bridge.
I tend not to play pre-written peices, though l listen to them all the time. The reason I learned theory from the get-go was so I could learn more tools to express myself when I improvise; as I find that whenever I improvise, it's 10 times more emotional...
As of now, my usual improvisation starts out by picking a scale in any given mode(usually minor), and 3-4 chordes within the scale for me to alternate between in my life hand, while picking out melodies as they come in my right hand. My bridges usually consist of 4-6 octave arrpagios which are raised or lower at the peaks...I mean, what else is there to do? haha
I'm trying to come up with something that will make my scale climbing more natural and more complex. Thus far, I usually alternate between the common "up one, down one, up three, repeat"...
So here's my question:What are some commonly used scale patterns in classical music?
