Key Switch is a simple and powerful chord transposer web app, and it's free to use! It should already be running in the panel on the right, with its "Welcome to Key Switch" window open.
If you don't see the Welcome to Key Switch window please read about what to do.
For general information see the Key Switch User Guide.
Here's the easiest way to get started with Key Switch and begin transposing chords and songs.
Choose a song from the "Try a Sample Song" menu. The selected song will immediately open in its own window in Key Switch's main workspace. Changing the key of the sample song click is simple. In the Key Picker panel, click one of the buttonssuch as A, Bb, B. That's it in a nutshell.
Alternately you can enter your own songs and chord charts—and that's the real point! To do so, click the Start a New Song button (or if KeySwitch is already open, click the New Song icon, the one with the + sign.)
Key Switch's "New Song" wizard escorts you through entering your song and setting its base key (i.e. identifying the correct key of the song. Key Switch needs to know the correct key in order to transpose with correct grammar.)
Either action opens the New Song wizard. After completing the wizard's three steps you'll be able to freely transpose your song.
KeySwitch has been around for quite a while, long before the various sites that allow you to transpose their versions of song sheets.
The advantages of KeySwitch are that you can:
Key Switch is easy to understand and operate, especially if you already have a grasp of transposing chords. So you might not even need to peek, but the Key Switch User Guide is a handy, in-depth resource. Though somewhat extensive, it's not entirely complete at present. We'll update Key Switch and its documentation on a continuing basis. That's a priority. Anyway, there's plenty of documentation to get you goin'. (Sorry that it's a bit rough and redundant in its current state!)
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.
