Both terms are different.
Non-copyrighted: Copyrighted Music cannot be used without the permission of its author. But when the music is copyright free (non-copyrighted), it is understood that it has no copyright on it, therefore it is free to use and this is usually indicated through a Creative Commons license.
Royalty-free: When a musical work is copyrighted, each time that work is used, the author receives a royalty, that is, a payment. Royalty-free music refers to music that, once bought or purchased, can be utilized without having to pay for each time it is used.
Note: Obviously, non-copyrighted music is also royalty-free music. But royalty-free music does not mean that it is always not-copyrighted.
My music on the section FREE Music is registered under a Creative Commons license CC-BY. This means that you can use it freely (even commercially) with the proviso that you put my name (Patrick de Arteaga) and the link patrickdearteaga.com there where you publish it.
Yes. You can use it anywhere, just remember you should give credit. In YouTube, for example, you can put my name in the video itself or in the video description. For example:
Music: Patrick de Arteaga (patrickdearteaga.com)
Yes. Also, being royalty-free music, you should not worry about sharing the benefits with me.
Yes. You can edit my music freely, remix it and create derivative works, as long as you distribute it, attribute my name Patrick de Arteaga with a link to this website, and indicate if any modifications have been made.
I do not make works for free. The only music for free that I compose is for everybody and I always make it by my own decision, no responding to requests. If you want exclusive music for you, I make paid commissions.
You ask, I make. I will send you a private link so you can hear the result. If you like it, I send you an invoice by e-mail (payment through PayPal), once the payment is done I will send you the audio file in WAV/MP3/OGG formats; and if you don’t like it, I make for you something else… Don’t you want me to make anything else? No problem, we cancel the commission, I understand that I failed to satisfy you and guilt is only mine.
Obviously, prices may vary according to the characteristics of the request, but my base price is $40 USD per minute of track composed. In principle, I do not collect royalties.
I cannot promise that the work will be finished in the same day that it has been requested, I am not so talented, I need my time to submit quality work.
All of my commission works are protected by copyright, and when you pay for them, you get, exclusively for you, the exploitation rights of the work.
I provide you with an assignment of copyright contract legally signed by me.
Formerly I used to use MIDI synthesizers on a Korg Pa800 Professional Arranger Keyboard after composing on my PC with Cakewalk Pro Audio program (predecessor of the current Sonar).
I am currently using Propellerhead Reason 10 with his complete mastering options.
Safe Creative is the website where I register my works intellectual property and assign Creative Commons licenses or Copyright. They have more than 10 years of experience and a great advisory service, in addition to their own social network.
