[Week 1] Jazz Solo - generated music is very strange

Hello,

I have completed the exercise of Jazz Solo and I was graded 100/100. However, the generated music is 13 seconds long and does not sound as real at all. Actually it sounds like someone presses piano keys one at a time with pause between key strokes with a second.
Do you have any idea what went wrong with it?

Regards,

I do not know. I have not heard that description.

Most students say that the generated music sounds like it came from an 8-bit video game, not from a jazz work.
