The Vienna Philharmonic's musical style is the result of its traditions and unique ensuing sound. The Viennese woodwind instruments sometimes have a different fingering system and a different form of mouthpiece or special reed. This is particularly noticeable with the Viennese oboe. The Viennese brass instruments, such as the trumpet, for example, have a rotary valve system and a somewhat narrower bore. Similar equipment also enables the trombone and Viennese tuba in F to produce improved tone colour and dynamics.
However, it's the Viennese horn in F that has the most significant differences from international instruments. Its sound quality is not as sharply defined, allowing smoother slurring. However, the Viennese timpani also have some special features. All the skin percussion instruments are covered with natural skins, in fact with goat skin heads, which produce richer overtones than plastic heads. And last but not least, we must mention the famous Viennese string sound. This is not so much based on the particular quality of the individual instruments, but rather on the specific Philharmonic playing style.
