Dear Jmsuijkerbuijk, There is no legal requirement that you - the copyright owner - limit your recordings to a sample of 1:45. This limitation would only apply if you are recording the copyrighted work of another composer. The sample length varies by country also. As copyright owner, you have full rights to post a complete recording here - which we urge you to do as it gives users a far better idea of what your music sounds like.

I'm not sure whether this is the appropriate way to react, but I don't know of any other way than by editing this section. Please forgive me if this is not the right way to do so. The restriction to one minute and forty-five seconds for audio samples has been given to me by BUMA-STEMRA, the Dutch organization for copyright control. The restriction was mentioned upon my question for possible limitation of sound samples on my own web site. I have applied that restriction to sound samples everywhere ever since. I must add that this restriction is foremost based on the fact that samples of 1'45" or less can be given on a web site without fees due; longer samples are allowed but will be billed by BUMA-STEMRA. Hence the applied restriction. J.M. Suijkerbuijk 00:59, 18 July 2011 (GMT)
That is indeed very interesting. 1:45 it has to be then. Carolus 02:24, 12 November 2011 (UTC)
Dear Composer or Copyright Owner,
s a composer or other copyright holder, please take time to carefully review the Creative Commons and licensing policies and guidelines.
For those uploading the first time, please remember choose the menu option "New Composition" when uploading your original works (even if they are scans of manuscripts or printouts), "New Arrangement" when uploading new arrangements, and "New Edition" when uploading new editions of public domain works. As it is normally assumed that composers and arrangers have edited their own work, please leave the "Editor" field empty unless another person has actually edited your work (in which case their name should be inserted). Note also that the English term "Editor" is not the equivalent of the French editeur or Italian editore. "Editor" refers to the person who reviewed and corrected the piece, while the French and Italian words are closer to the English word "publisher". In the "Publisher" field, please use your own full legal name, as making your scores and sound files available for free download on this site constitutes "publication" under the laws of most countries in the world. (Note that this is done automatically when using the standard upload tools).
You should be aware that Creative Commons Attribution 4.0 allows for the unrestricted copying, performance (live and broadcast) and recording of the work (including explicitly commercial use) at no charge, with no compensation or royalties payable to the composer or copyright owner for such commercial exploitation. Note also that the all of the acceptable licenses are considered to be IRREVOCABLE once a file has been uploaded with the lawful copyright owner's authorization.
You are free to change the license after upload to something more suitable. IMSLP as a matter of policy will list files under the most permissive licensing terms. Since licenses and public domain dedications are irrevocable, restrictions cannot be added later, but a more liberal license can be selected. Composers are also encouraged to make use of our new template {{NoPerf}}, which automatically places works into a new category - Unperformed Works. To add this template to your pages, simply copy and paste the little template above (curly brackets and all) into the "First Performance" field of the "General Information" section on all work pages.
Before you upload, remember these key points...
PS: For additional and more detailed explanation, please visit our Composer Portal page.
Thank you for the information. I will contact BUMA/STEMRA and present them both the IMSLP Performance Restricted License and the Creative Commons Attribution Non-commercial No Derivatives 3.0. I will get back on that as soon as I have an answer from them (may take a while). J.M. Suijkerbuijk 10:53, 12 November 2011 (GMT)
