I think he would be bigger than the Rolling Stones and U2 combined.

he would be decomposing..

I would prey to God for his sake he wouldn't look in at a disco. That would finish him off.

I think the world is as crazy today as it was in Mozarts time. One of the differences is communications and how much craziness we now get to find out about!

I think he would think it is loud.

I think he would be happy to go back where he was- his grave.

I think it would kill him off!

Nobody appreciates the classics today. He'd probably be a piano tuner than a composer.

Interesting question. Each of us see the world in the in the way we do by assigning symbols to remind us of similar terms of meaning and intent. An artist describes the world in lines and colors that to them symbolize the world they see, with realism to abstraction over a broad gradient of potential forms of expression. The same applies to a music composers vision of the world where events can be expressed in music to symbolize a dry and arid day, a distant approaching storm, the cooling, ruffling, moist breeze, the first drops of rain  and the clap of thunder and flash of lightening. The musical composer faced with the same challenge has the breadth of instruments and sounds as a writer has words , as an artist has colors, patterns, textures lines and forms.

         Mozarts world gave him the opportunity to express his genius in his music, his love of this form of personal expression gave all of us an insight  into our own potential for personal expression here...now.     

I would really be interested in where music would be today if in fact the masters like Chopin, Mozart, Hayden, Liszt,  etc. had the technology that we have today in creating music, ie., software, synthesizers. I am sure that they would have made use of it as much as today's masters of music use it. Unfortunately, like any of the arts, we never know who the real masters are until they die..
