The fingering technique of the bassoon varies more between players, by a wide margin, than that of any other orchestral woodwind. The complex mechanism and acoustics mean the bassoon lacks simple fingerings of good sound quality or intonation for some notes (especially in the higher range), but, conversely, there is a great variety of superior, but generally more complicated, fingerings for them. Typically, the simpler fingerings for such notes are used as alternate or trill fingerings, and the bassoonist will use as "full fingering" one or several of the more complex executions possible, for optimal sound quality. The fingerings used are at the discretion of the bassoonist, and, for particular passages, he or she may experiment to find new alternate fingerings that are thus idiomatic to the player.
