Not necessarily! If it was 'for what' then you could have been asking 'what is it a suitable sound for?' (Unlikely. But. You see?) I did think it was most likely the same as pourquoi, but IT IS BEST TO CHECK. YOU AND YOUR SPANISH.

Why? I don't know if I could isolate a reason. I always need calm music to write anything to - anything too heavy and the rhythm/words intrude on the rhythm/words I'm producing. And the Lucifer-mindset is very calm. It needs to be quiet and precise and with room to read people in.
