If Web content contains audio of instrumental music, provide a text alternative that identifies the music and makes it clear that it does not include a vocal component.
A text alternative that provides the title of the piece and identifies the composer and/or performer(s) may be sufficient. In some cases, it may be appropriate to provide a brief additional description of the piece. Again, consider the context in which the audio occurs and the purpose for which it is used when deciding how much additional information to provide. It may also be appropriate to write such descriptions in a style suited to the purpose and context: for example, a scholarly description would be quite different from a description on a popular music site.
For information about providing text alternatives for music that includes words, see the section on text alternatives for audio recordings, earlier in this document. Be aware, however, that it may be illegal to include the lyrics of songs for which you do not own the copyright. In such cases, it may be appropriate to provide a summary of the lyrics .
Do not assume that people who are deaf or hard of hearing have no interest in music!
Editorial Note: Need to include examples.
