Newbie question on keys

[pdxdjazz]

Transposing can be confusing.
The global setting for transposed instruments transposes the chords in ALL the charts to reflect the interval between your instrument and the concert key. The iRp player continues to play in concert while the chords for your instrument are displayed.

The bottom-right transpose button changes the concert key for only the displayed chart. (Which will display the new chords for your instrument, unless the global transpose function is set to C, in which case the concert chords will be shown)
