Why I am dedicating these works to the Public Domain:

I produce a lot of audio content, and post much of it to my main site at incompetech.com. After a number of years, and many many downloads - some pieces are clearly not commercially viable in the traditional sense, and just add clutter which hinders people in finding the pieces that they may want.
For these pieces, I've started this site - to distribute the works into the Public Domain. I do not believe music that is not commercially viable has no value - and I would like the music to find as much potential as possible.

Can I request a piece of music?

No. I do not accept requests for music to be dedicated to the Public Domain.

Do I need to attribute the music in my work?

No. There are no restrictions on usage. You may choose to attribute to the listed composer, but it is not required.

Can I donate to this site?

I am not accepting donations at this time. You may feel free to link to this site, and tell people about it.

I have music that I would like to dedicate to the Public Domain... how can I distribute that music here?

Please email me at kevin@incompetech.com, and attach the piece of music.

Can I download and sell this music?

Yes. You may not reassert copyright on the materials that have already have been placed into the Public Domain.

Can I remix the music here, and sell it?

Yes. You will have copyright on the derivative work. At that point it becomes a new piece, and you may do whatever you like with it.
