You can change the enharmonic spelling of chord symbols for transposing instruments; for example, to choose a simpler enharmonic equivalent spelling. This changes the enharmonic spelling of chord symbols in all transposing layouts and for all instruments with the same transposition.
Procedure
Result
The spelling of the chord symbol is changed in transposing layouts for all instruments with the same transposition. For example, changing the spelling of a chord symbol for a Clarinet in B♭ also changes the spelling of that chord symbol in the part layout for a Trumpet in B♭.
