.. container:: example
**Example 1.** Inverts twelve-tone row about first pitch-class
in row when `axis` is none:
::
>>> row = pitchtools.TwelveToneRow(
... [1, 11, 9, 3, 6, 7, 5, 4, 10, 2, 8, 0]
... )
::
>>> row.invert()
TwelveToneRow([1, 3, 5, 11, 8, 7, 9, 10, 4, 0, 6, 2])
First pitch-classes of prime form and inversion are equal.
.. container:: example
**Example 2.** Inverts twelve-tone row about pitch-class 1:
::
>>> row = pitchtools.TwelveToneRow(
... [1, 11, 9, 3, 6, 7, 5, 4, 10, 2, 8, 0]
... )
::
>>> row.invert(axis=1)
TwelveToneRow([1, 3, 5, 11, 8, 7, 9, 10, 4, 0, 6, 2])
Same result as above because 1 is the first pitch-class in row.
