Although
woodwind instruments and
string instruments have no theoretical upper limit to their range (subject to practical limits), they generally cannot go below their designated range.
Brass instruments, on the other hand, can play beyond their designated ranges. Notes lower than the brass instrument's designated range are called
pedal tones. The playing range of a brass instrument depends on both the technical limitations of the instrument and the skill of the player. Classical arrangements rarely make woodwind or brass instruments play beyond their designed range. String musicians play the bottom of their ranges very frequently, but the top of a string instrument's range is rather fuzzy, and it is unusual for a string player to exceed the designated range. It is quite rare for wind musicians to play the extremes of their instruments. The most common exception is that in many 20th century works, pedal tones are called for in bass trombones. This chart uses standard numberings for octaves where
middle C corresponds to C4. In the
MIDI language, middle C is referred to as MIDI note number 60. The lowest note that a
pipe organ can sound (with a
true pipe) is C−1 (or CCCC), which is 8 Hz,
below the range of human hearing and not visible on this chart. However, if acoustic combination (a note and its fifth) counts, the lowest note is C−2 (or CCCCC), which is 4 Hz. In terms of recording and reproduction, many speakers have a low limit of around 40–60 Hz. == Typical ranges ==
