**Example 1.** Inverts pitch around middle C explicitly:
::
>>> NamedPitch("d'").invert("c'")
NamedPitch('bf')
::
>>> NamedPitch('bf').invert("c'")
NamedPitch("d'")
Default behavior.
**Example 2.** Inverts pitch around middle C implicitly:
::
>>> NamedPitch("d'").invert()
NamedPitch('bf')
::
>>> NamedPitch('bf').invert()
NamedPitch("d'")
Default behavior.
**Example 3.** Inverts pitch around A3:
::
>>> NamedPitch("d'").invert('a')
NamedPitch('e')
Interprets none-valued `axis` equal to middle C.
Returns new named pitch.
