Huh?? A tonality is the tonal character of piece of music determined by the relationship of tones to it's keynote (tonic). Like you could say the major scale has the "major" tonality. Because all the intervals or scale degrees are a major interval from the keynote. Take G major, G-A major second, G-B major third, and so on.

All music has a tonality, even Indian music which is quarter-tone. So piece sould still be said to be in Fb major(not enharmonic E, but a flat F). Turkish music is eigth-tone, so there pitches are measured as 25 cents. (Not money) heh

I think you confused tonal music with tonality. ;)
