It's track 9.  "9" is pronounced "tenth".
Cf. the fact that $foo[3] is item 3, i.e., the "fourth".

Many descriptions of MIDI go and number from 1 (so, they call channel 0
"channel 1", and so on up) because it's too "confusing" to number from 0.
But the file specification and the raw protocol both start at 0 (for note
numbers as well as channels), so that's what I do.

See, for example, code in
http://www.speech.cs.cmu.edu/~sburke/midi-perl/tpj_13_midi.html
like:
 noop c9, ff, n41, qn;  # The setup...
 n; r; n; r;            # ...and the work.
