chord-transposer is a simple web app for transposing a chord progression into another key.
The user inputs plain text into a textbox, containing their chords and possibly formatting data.
The chords are extracted from the plain text, transposed into the desired key, then outputted
on the webpage.
You can try it out here. For a more in-depth description of how the app works under the hood, see the DESCRIPTION.md file.
