ambitus

[Werner LEMBERG]

This really hurts:

  The term ambitus (plural: ambituses) denotes a range of pitches for
                            ^^^^^^^^^
  a given voice in a part of music. It also may denote the pitch range
  that a musical instrument is capable of playing.

The plural of `ambitus' is `ambitus'.

According to

  http://www.dolmetsch.com/defsa.htm

a possible translation to English is `ambit' which would have `ambits'
as the plural.  Cf.
