Manual Transpose
Transpose
How to
To perform a transpose on the fly, you will find a toolbar button on the chart preview page.
But the app doesn't know anything about musical keys.
It just shifts the chords by the number of semitones you select in the drop-down list.
So you have to find the right key yourself.
If you are transposing down you might get flats (♭), and if you are going up you might get sharps (♯).
original chart
For example, Your Song chart is written in C but uses a capo on the third fret.
transpose up
So the obvious thing would be to transpose it up three semitones (like the capo does). But the result looks at least a bit unusal.
transpose down
You want the right key, which is E♭. So instead of going up three steps, you have to go down nine semitones.
Transpose within text snippets
To also transpose the name of the key in section titles and annotations, you must include them with square brackets [ ].
See this example in the features section.
