just a note, this is my rendition, it's not the true version, but it is the same melody

Intro X2(in 4/4 as I'm trying to show)
Emin 2 3 D
Emin 2 3 D
Emin 2 3 D
C2   D G D

Chorus (or head, if you will, and it's in 4 still by the way)

Emin 2 3 4  Amin 2 3 4
O        Fortuna,
Emin 2 3 4  Amin 2 3 4
ve------lut luna
C2 2 3 4   Amin 2 3 4 Emin 2 3 D Emin 2 3 D
     statu var-----ia--bilis,

(Okay this section is interesting.  It switches between 5/4 and 4/4, but I'll count it out.  I separated it into a 3 verse thing, but I don't htink it's actually sung that way chorally, as Orff takes more liberties, but I like the symetry of the poem too much to pick and choose it)

Verse 1

Emin 2 3   D 5
     O For-tuna,
Emin 2 3   D 5
     velut luna
Emin 2 3   D
     statu var-
C2 D G  D
i- a-bi-lis,
  semper crescis
  aut decrescis;
vita detestabilis
  nunc obdurat
  et tunc curat
ludo mentis aciem,
  egestatem,
  potestatem
dissolvit ut glaciem.

(might as well keep it all verse chorus I always say)

  Sors immanis
  et inanis,
rota tu volubilis,
  status malus,
  vana salus
semper dissolubilis,
  obumbrata
  et velata
michi quoque niteris;
  nunc per ludum
  dorsum nudum
fero tui sceleris.

  Sors salutis
  et virtutis
michi nunc contraria
  est affectus
  et defectus
semper in angaria.
  Hac in hora
  sine mora
corde pulsum tangite;
  quod per sortem
  sternit fortem,
mecum omnes plangite!

(If you have any questions, then you are probably inquisitive)
