The Transpose tool does not save files or create song sheets. Chordsongs is available for creating song sheets for multiple instruments at chordsongs.mandozine.com
Sorry, the Transpose tool does not work with mobile devices.
The Transpose tool is intended for exploring various keys of songs you play or want to learn. Use the Chord Entry button for entering chords. The transpose step buttons are for transposing to another key. Entering chords when the step buttons are selected will enter the wrong chords since they are not mapped directly to the keyboard.
If you see unicode characters instead of chords, the script is still working. Wait a few moments and try again.
Note: Do not copy and paste the chords to another app, they will only display as unicode characters. If you want chord fonts to use on your computer, check out Chordette. Chordette is available in several tunings for most stringed instruments, and will transpose between tunings by changing the font.
