To answer haifagirl’s original question:
No, there are no specific tones, intervals or notes that are intrinsically Jewish; no more so than there are specific, isolated ingredients that are intrinsically one culture’s food. It’s what is done with the musical ingredients that make the dish.
Jewish music usually morphs over time to resemble the music of its surrounding cultures, with the one key difference being that the goal of the song is historically either D’veykus or Simcha. As someone pointed out above, there may be Jewish songs whose lyrics are angry, but the music itself is usually still upbeat.
In other words: the “Jewish” aspect of Jewish music is the product, not the ingredients. So, to ask if, say, an A-minor is a Jewish note is like asking if a kernel of corn is Mexican food.
