The universal transposer and Nashville Number engine.
What is Chord Genius?
Whether you need to shift a song's key to fit a singer's vocal range, or you want to prep a chart for a full band, Chord Genius does the heavy musical math for you. It instantly converts standard chords into any new key, or into the universal Nashville Number System.
How to Use It
1. Find Your Chart: Type a song name to instantly pull a chart from Ultimate Guitar's database, or upload your own local document.
2. Verify the Original Key: We attempt to auto-detect the song's starting key. If it looks incorrect, you can manually override it using the Orig Key dropdown.
3. Transpose or Convert: To transpose a song, select your new To Key. To generate a universal number chart, leave it set to "Nashville". (Pro-Tip: If you are uploading a chart that is already in numbers, select "Nashville Numbers" as your Orig Key!)
4. Download: Choose your format (.DOCX for easy editing, or .PDF for a stage-ready layout) and hit convert!
⚠️ Note: Charts scraped from the web rely on the original author's accuracy. Always double-check that the starting key makes sense for the song!
