Concert pitch


The pitch that non- transposing instruments sound.The tuning pitch of an ensemble. Instruments in a band or orchestra tune to the concert pitch which is typically the universal standard A' = 440 Hz. While concert pitch is non- transposing, a variety of wind instruments, such as the trumpet, clarinet, and horn are transposing instruments, indicating that the pitch A' , as relating to that instrument, will not be sounded as an A' concert pitch but rather a pitch called an A' on that instrument. Thus, when a B-flat trumpet plays an A' (first and second valves), the instrument is actually sounding a G' concert pitch.
