hamsters perfer soft music
It depends on what music you play. Hamsters are calm and peaceful when they listen to classical music (they may even sleep because they are so relaxed). But, if they listen to rock music they may get a bit jumpy and can get nervous. You could experiment with lots of different types of music, but hamsters probably prefer listening to classical music.
yes
Depends on your hamster.
Hamsters can be 'fooled' or trained into stepping onto a very select (1-5) amount of instruments such as piano keys. But they will not intentionally or knowingly produce music.
You'll have a dead hamster
They have been proven to be ineffective long term-even for hamsters.
I have had no problems with playing music when my hamsters sleep, as long as it is quiet. If you notice that they are having disturbed sleep, particularly when you are playing music, maybe stop :)
Hamsters can react to music in different ways. Some may be calmed by classical music, while others may be agitated by loud or fast-paced music. It's best to observe your hamster's behavior and adjust the music accordingly to see what they respond to positively.

Yes, I think people can efect the mood of hamsters. They make them feel a variety of emotions. From feeling like home to scaring them.
