Faking

One of the "great unmentionable of orchestral playing" is " faking ", the process by which an orchestral musician gives the false "... impression of playing every note as written", typically for a very challenging passage that is very high or very fast, while not actually playing the notes that are in the printed music part. An article in The Strad states that all orchestral musicians, even those in the top orchestras, occasionally fake certain passages. One reason that musicians fake is because there are not enough rehearsals. Another factor is the extreme challenges in 20th century and 21st century contemporary pieces; some professionals said "faking" was "necessary in anything from ten to almost ninety per cent of some modern works". Professional players who were interviewed were of a consensus that faking may be acceptable when a part is not written well for the instrument, but faking "just because you haven't practised" the music is not acceptable.
