In lot's of jazz books, i see people saying that when you are playing a 2 5 1 chord progression, you can play a dorian on 2 and mixolydian on 5 and ionian on 1.
Now basically, all 3 of those modes use the Same notes , they just end on different notes. as in the case with dorian on d and mixolydian on G for 2 and 5 respectively.
Are you all able to make them sound different somehow ?
Not only these three, but all seven modes use the 'same notes', in the sense that they are all based on the same intervals as a major scale but starting on a different degree. In other words, a mixolydian scale starting on G is the fifth mode of C major. Ionian mode is identical to a major scale. They will sound different purely by where they start and end.
If you are improvising, though, you might do well to be a bit more creative than just playing scales. The chords that go with these scales equate to D-7, G7 & C. Try and drop chord notes on beats 1 and 3. You can try going outside the scale, using chromatic notes. Experiment and see what it sounds like. Listen to the masters, see how they do it. Timing is crucial.
