The Choral Public Domain Library (CPDL) is a sheet music archive which focuses on choral and vocal music in the public domain or otherwise freely available for printing and performing (such as via permission from the copyright holder).
It is a 501(c)(3), tax-deductible organization, [1] whose contents are published under a specific copyright license, and editing articles can be allowed only for registered contributors.
The site CPDL.org was launched in December 1998 by Rafael Ornes. [2] [3] In 2005 CPDL was ported, or converted, to wiki format, and is known as ChoralWiki. [4] In July 2008, Ornes stepped back from the site administration and turned the operational responsibilities to a group of the site administrators. A transition committee was formed which subsequently incorporated CPDL as a non-profit under California state law and now operates CPDL. [4]
In addition to making sheet music scores available, the wiki format supports additional features including:
Music is available for free download in a variety of formats, including score images in PDF, PS and TIFF format, sound files in MIDI and MP3 formats, and in the notation formats supported by various notation programs, including Finale, Sibelius, NoteWorthy Composer, Encore, and the open source GNU LilyPond. Most scores on CPDL are distributed under an open-source license. As of 1 December 2017, CPDL archives over 27,800 scores by more than 2,900 composers, contributed by over 1,200 editors and contributors. [5] It includes large numbers of scores from the Renaissance and Baroque eras, including nearly complete vocal works by William Byrd and Tomás Luis de Victoria in excellent editions.[ citation needed ]
CPDL is suggested as a resource by departmental or faculty websites at Kent State University, Northern Illinois University, the University of Oregon, the University of Western Ontario, the Internet Public Library of the University of Michigan, the University at Albany, The State University of New York, by the UCLA Music Library, by the libraries at the Universities of Boston [6] and Stanford and by inclusion by faculty members in syllabi for courses at the University of Wisconsin–Oshkosh. [7] It is recommended by the Iowa and Massachusetts chapters of the American Choral Directors Association, and is included in the resource database of Intute, an association of Institutions in the UK. [8]
Jason Sickel has described the CPDL as a Gold Mine for Choral Directors. [9]
Contents are published under a specific copyright license, if not otherwise specified [10] and based on the GNU GPL license.
License is based on the principle that if users distribute copies of a musical work under the CPDL license, whether gratis or for a fee, they must give the recipients all the rights that they already have. [10] Any modified Edition must be caused with the related date and any distributed copy must refer the copyright notice, whether gratis, or for a fee.
In that way, the same right of asking a fee may also be applied by the copyright holder, possibly with an exception for works listed in the U.S. public domain. As a copyright license, evenf if derived by GNU GPL, the license terms can be radically modified anytime, while they don't provide the universal and fundamental rights into a specific and permanent section of the license terms, that can be modified only under a very large agreement of the community, or not be modifiable at all.
From a more operative point of view, it underlines and implies that all the source code in any article can be viewed by anyone, copied, reproduced on different Wiki engines or long-time preserved on specific websites like the Internet Archive or archive.is.
The Artistic License is an open-source license used for certain free and open-source software packages, most notably the standard implementation of the Perl programming language and most CPAN modules, which are dual-licensed under the Artistic License and the GNU General Public License (GPL).
Free software or libre software is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions. Free software is a matter of liberty, not price; all users are legally free to do what they want with their copies of a free software regardless of how much is paid to obtain the program. Computer programs are deemed "free" if they give end-users ultimate control over the software and, subsequently, over their devices.
The MIT License is a permissive free software license originating at the Massachusetts Institute of Technology (MIT) in the late 1980s. As a permissive license, it puts only very limited restriction on reuse and has, therefore, high license compatibility.
Open-source licenses facilitate free and open-source software (FOSS) development. Intellectual property (IP) laws restrict the modification and sharing of creative works. Free and open-source software licenses use these existing legal structures for the inverse purpose of granting freedoms that promote sharing and collaboration. They grant the recipient the rights to use the software, examine the source code, modify it, and distribute the modifications. These licenses target computer software where source code can be necessary to create modifications. They also cover situations where there is no difference between the source code and the executable program distributed to end users. Open-source licenses can cover hardware, infrastructure, drinks, books, and music.
Free music or libre music is music that, like free software, can freely be copied, distributed and modified for any purpose. Thus free music is either in the public domain or licensed under a free license by the artist or copyright holder themselves, often as a method of promotion. It does not mean that there should be no fee involved. The word free refers to freedom, not to price.
The Mutopia Project is a volunteer-run effort to create a library of free content sheet music, in a way similar to Project Gutenberg's library of public domain books. It started in 2000.
A permissive software license, sometimes also called BSD-like or BSD-style license, is a free-software license which instead of copyleft protections, carries only minimal restrictions on how the software can be used, modified, and redistributed, usually including a warranty disclaimer. Examples include the GNU All-permissive License, MIT License, BSD licenses, Apple Public Source License and Apache license. As of 2016, the most popular free-software license is the permissive MIT license.
The ISC license is a permissive free software license published by the Internet Software Consortium, now called Internet Systems Consortium (ISC). It is functionally equivalent to the simplified BSD and MIT licenses, but without language deemed unnecessary following the Berne Convention.
The WTFPL is a permissive free software license. As a public domain like license, the WTFPL is essentially the same as dedication to the public domain. It allows redistribution and modification of the work under any terms. The title is an abbreviation of "Do What The Fuck You Want To Public License".
The International Music Score Library Project (IMSLP), also known as the Petrucci Music Library after publisher Ottaviano Petrucci, is a subscription-based digital library of public-domain music scores. The project, which uses MediaWiki software, has uploaded more than 630,000 scores and 73,000 recordings of more than 195,000 works by 24,000 composers. IMSLP has both an iOS app and an Android app.
License compatibility is a legal framework that allows for pieces of software with different software licenses to be distributed together. The need for such a framework arises because the different licenses can contain contradictory requirements, rendering it impossible to legally combine source code from separately-licensed software in order to create and publish a new program. Proprietary licenses are generally program-specific and incompatible; authors must negotiate to combine code. Copyleft licenses are commonly deliberately incompatible with proprietary licenses, in order to prevent copyleft software from being re-licensed under a proprietary license, turning it into proprietary software. Many copyleft licenses explicitly allow relicensing under some other copyleft licenses. Permissive licenses are compatible with everything, including proprietary licenses; there is thus no guarantee that all derived works will remain under a permissive license.
A free-software license is a notice that grants the recipient of a piece of software extensive rights to modify and redistribute that software. These actions are usually prohibited by copyright law, but the rights-holder of a piece of software can remove these restrictions by accompanying the software with a software license which grants the recipient these rights. Software using such a license is free software as conferred by the copyright holder. Free-software licenses are applied to software in source code and also binary object-code form, as the copyright law recognizes both forms.
BSD licenses are a family of permissive free software licenses, imposing minimal restrictions on the use and distribution of covered software. This is in contrast to copyleft licenses, which have share-alike requirements. The original BSD license was used for its namesake, the Berkeley Software Distribution (BSD), a Unix-like operating system. The original version has since been revised, and its descendants are referred to as modified BSD licenses.
Copyleft is the legal technique of granting certain freedoms over copies of copyrighted works with the requirement that the same rights be preserved in derivative works. In this sense, freedoms refers to the use of the work for any purpose, and the ability to modify, copy, share, and redistribute the work, with or without a fee. Licenses which implement copyleft can be used to maintain copyright conditions for works ranging from computer software, to documents, art, scientific discoveries and even certain patents.
The GNU General Public License is a series of widely used free software licenses that guarantee end users the four freedoms to run, study, share, and modify the software. The license was the first copyleft for general use and was originally written by the founder of the Free Software Foundation (FSF), Richard Stallman, for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. These GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. It is more restrictive than the Lesser General Public License and even further distinct from the more widely used permissive software licenses BSD, MIT, and Apache.
The GNU Free Documentation License is a copyleft license for free documentation, designed by the Free Software Foundation (FSF) for the GNU Project. It is similar to the GNU General Public License, giving readers the rights to copy, redistribute, and modify a work and requires all copies and derivatives to be available under the same license. Copies may also be sold commercially, but, if produced in larger quantities, the original document or source code must be made available to the work's recipient.
Software categories are groups of software. They allow software to be understood in terms of those categories, instead of the particularities of each package. Different classification schemes consider different aspects of software.
Software relicensing is applied in open-source software development when software licenses of software modules are incompatible and are required to be compatible for a greater combined work. Licenses applied to software as copyrightable works, in source code as binary form, can contain contradictory clauses. These requirements can make it impossible to combine source code or content of several software works to create a new combined one.
Open source license litigation involves lawsuits surrounding open-source licensed software. Many of the legal rights of open source software licensors enforceable against users violating licensing agreements are untested by the U.S. legal system. Free and open source software (FOSS) is distributed under a variety of free-software licenses, which are unique among other software licenses. Legal action against open source licenses involves questions about their validity and enforceability.
