Is there any public general definitions database?

[Mcod]

Hi there,

 

I wonder if someone knows a public definitions database (like a mysql dump etc) for general words. What I am basically after is a database which you can query for something like "music" and it returns something like google's define:music where the result would be

 

"The art or science of combining vocal or instrumental sounds (or both) to produce beauty of form, harmony, and expression of emotion."

 

Would be great if you could point me to something like this.

 

Thanks in advance
