Transpose a song for your singer
The rehearsal problem: the chorus sits too high for the singer, but the band already has a chord chart. Try a lower key with the singer, then make one clear chart everyone can follow.
A four-chord example
Suppose your original chart is in C with C – G – Am – F. If the singer is more comfortable two semitones lower, change the song key to B♭. The same progression becomes B♭ – F – Gm – E♭. Its Roman-numeral pattern stays I – V – vi – IV, which helps the band see the progression even when the letter names change.
Make the chart in Chord Scribe
Paste lyrics you wrote or have permission to use, and choose C as the song key.
Place C, G, Am and F over the words where the changes happen.
Try the chorus with the singer. If B♭ works better, change the song key; Chord Scribe transposes the placed chord symbols.
Drag a chord to the exact word or syllable you want, adjust its width to cover more or less of the phrase, and show Roman-numeral labels when the band wants both ways of reading the changes.
Preview and save the chart. Rehearse it once with the whole band before the performance.
Changing the chart’s key does not choose a comfortable vocal range for you. Let the singer decide by singing the hard phrase, then check that the guitar and other instruments can play the new key.
