Welcome to the Xenharmonic Wiki!

The Xenharmonic wiki is an open resource for information about Musical Tuning. This includes information about systems of tuning, the relationships between those systems, and the theory and math behind them.

This wiki is created by volunteers. Relevant new content is most welcome! You can get the hang of editing in the Sandbox, then dive right in. Wiki Help provides some tips as well. Wikifuture is a wish list of sorts.

If you are new to musical tuning:

• Why use alternative tunings? is an overview of common reasons for learning about tunings other than standard western tuning.
• The Approaches to Musical Tuning page offers links to various theoretical approaches to exploring alternative intonation systems
• Here are links to lots of alternatively tuned music that has been made, in case you're wondering what it all sounds like.
• Links to xenharmonic websites: Maps | Forums | Educational websites | Labels and concert producers
