There are several ways you can use musical works and sound recordings in the classroom, including:
 

Copying or distributing for a class 

• Under the MRU Fair Dealing Guidelines, a MRU employee may copy and distribute a "short excerpt" (up to 10%) of a musical work that is in the form of individual sheet music (unless the use is barred by a license).
• If the musical work (sheet music) is published in a book containing other musical works (sheet music), you may copy or distribute one entire musical work (unless it is available at a reasonable price in a reasonable time frame on its own).
• You may also copy or distribute up to 10% of a sound recording as long as the copy is obtained in a legal manner. 

Note: Copies of "short excerpts" of musical works and sound recordings are only to be provided to students enrolled in a course of study; to other MRU faculty members and administrative staff of the university; and/or to faculty members or students at another university with whom the faculty member is engaged in collaborative research. As well, distribution should never occur to an open Internet website or other public forum.
 

Performing for a class

• Performances of musical works or sound recordings in class by instructors and their students are covered by section 29.5 or section 32.2(3) of the Copyright Act.
• If your use does not fall under the conditions of these provisions, you must contact the copyright owner for permission to perform the musical work or sound recording. 

Note: These educational user rights both allow for the performance of an entire musical work and sound recording (i.e. you are not limited to a "short excerpt" — up to 10% — of the musical work).
