David Bill Evan's 12 tone tune is the only atonal jazz composition I can think of if there are more please let me know. Again I think you are confusing modulation with tonality which has a very specific meaning. Atonality is a compositional technique that was developed by Arnold Schoenberg and is the systematic avoidance of permitting any single pitch to sound as a tonal center. There were a variety of ways that these composers accomplished this that I won't go into here. But the point I'm trying to make is that tonality is achieved at the compositional level not the performance level. The altered extensions a jazz pianist uses has nothing at all to do with whether or not the piece is tonal or atonal. If instead what you are saying is that jazz musicians prefer to achieve color with their choice of chord extentions rather than unequal temperaments I agree with you and ,in fact, have stated that in this forum. I have to take issue with your first sentence, however. Jazzers improvise the melody, the rhythm the chord voicings but the one thing they don't improvise are the changes! You can certainly do that up front, have it on the lead sheet but that falls under the heading of composition or arranging not improvisation.
