Jamming with others

[Up-78]

Hi, I'm a student at Ohio State. Ive been playing with two other guys who have been classically trained in their instruments. I play an acoustic folk guitar and they play the violin and the piano. When we play to gether we usually just pick a major or minor key and play some progression while one of us improvises on the melody. Most of the time i play an accompaniment, since guitar is easier to play accompaniment on than the other two instruments.
However, when it's my turn to play the improv, my play doesnt go very well with theirs. Their accompaniment style is too stuck on classical music, and i only really know how to jam with the major and minor pentatonics (a much bluesier sound). I need some suggestions on what other scales would be good to learn to be able to improvise in the classical style. Also, I would like to find out what suggestions i can make to the other two, to make their music tend towards jazz or blues a little more.
Speaking of jazz, what are some good scales to play melodies to jazz?

For jazz: I'm new to jazz, but I've been ripping up the major scale. There are others like the lydian scale that work well too. Get a scale book. They usually explain what chords go well with what scales. The piano player should use more 7th chords. The violinist will most likely use the same scales as you. Start with the basic jazz
II-V-I progression. The trick to jazz is the "feel" or swing of it. Once that swing feel seeps down into your bones, you will begin to sound like a hepcat!

If you want to sound more classical: Again with the Major scale modes. Major, Minor, Phrygian are my favorites.

Stick around, there is bound to be more knowledgeable people to offer suggestions. Stone are you out there?
