Transpose songs! Free, online!
TheoreticallyCorrect.com unveiled Key Switch song transposer in late 2011 for free online use (in a public beta release.)
If you don't see Key Switch to the right of this panel, please read this section.
Jump right in. See Key Switch in action.
You can easily try out Key Switch here. Just select one or more songs from Key Switch's "Sample Songs" menu. Each song will open in its own window, ready to transpose. To change the key of a song just click the desired key in the Key Picker.
Built-in sample songs from various genres include:
Greensleeves
Nobody Knows You When You're Down and Out
It Came Upon a Midnight Clear
O Holy Night
Rose Room
You can also paste in other songs with. Steps for doing so are described in the User Guide
User Guide
The Key Switch User Guide provides lots of information about using Key Switch. Though the guide is somewhat extensive, it's only partially complete at present. We will update Key Switch and its documentation on a continuing basis. That's a priority.
Adobe Flash Player does not run on an iPhone or iPad and that means Key Switch cannot run on those devices. Read more about Apple and Flash.

Known Issues & Notes
As a public beta, this release includes some minor known issues:
- When viewing this web page with Internet Explorer 8 you might see only this column of text; if so you'll find Key Switch positioned awkwardly in the lower portion of this page. Intenet Explorer is the only browser with this display problem. We recommend using Firefox, which is a superior browser in countless ways. If you don't want to switch browsers then click for a full screen version of Key Switch.
- Key Switch will automatically run when you visit this page if the Flash Player 9 browser plug-in (or a later version) is installed on your computer. If you have Flash Player installed but you don't see Key Switch to the right of this panel, please read this section. Flash Player is installed on most computers. If Flash Player is not installed on system you can download Adobe Flash Player from Adobe's site. It's free and only takes a minute to get it and install.
- Key Switch's interface coloring is rather unattractive presently. This will change soon. It's even likely you're be able to pick a skin/theme of your choice, and personalize the look of Key Switch.
- Some buttons and objects are not ideally aligned with their surroundings.
- The status window presently provides a small amount of feedback and guidance. Soon it will serve as a much more robust guide to using Key Switch.
- As mentioned, the music applications here on TheoreticallyCorrect require Flash Player. Apple has intentionally blocked Flash from running on an iPhone and iPad. This stance is likely to continue until Apple and Adobe resolve their disputes.
- Apple's Safari browser sometimes has issues when running Flash applications. If Safari, or your Macintosh slows to a crawl, quit Safari and use Firefox. Firefox seems to coexist perfectly well with Flash. Quitting Safari often unburdens the processor(s) and returns the Mac to an uncrippled state, so that's an option too.
