If you play a wind instrument that reads in a key other than C, iReal Pro prints every chart in your instrument's key while the backing track keeps playing in concert pitch, just as it would in a band. The setting is global and applies to every song until you change it.

 

In song view, tap the chord chart settings button at the top, which reads Aa on iPhone and iPad and A on Android. Tap Transposing instrument and choose yours from C, Bb, Eb, F and G.

 

The chart shows a part label, such as Eb-Part, beside the style whenever an instrument other than C is selected. The key in the player controls is always the concert key, the key a piano or guitar would be playing in.
