Pitch and duration?
I didn't write the code, but I'm a musician, so I can see where he's going.
This is probably an over-simplification for you, Andrew, but pitch is the
frequency (generally expressed in Herz); and duration is how long to hold
the note. A musician would think in terms of quarters, eighths (or quavers
and semi-quavers, depending on which side of the pond you're on), but the
computer is probably thinking in milliseconds.
I doubt that pitch is 4 Hz. I suspect a bug in the code. The OP may want to
get the 4th of a table of pitches, and the 10th of a table of durations. He
will get instead the 10th element of the 4th element.
Multidimensional arrays throw a lot of people. Again, if this is to simple
for you, skip it. Let's say you have an array of teachers, and each teacher
has certain students.
Mr. Smith
Jane
Johnny
Suzie
Larry
Curly
Moe
Mr. Jones
Richard
Dick

Ritchie

Mr. Wang
Li Pengyou
Deng Xiaoping
Ding Ling
Tan Kai Rui
StudentArray[3][3] would be "Ding Ling", because you're getting the third
teacher's third student.
Cordially,
Kerry Thompson
P.S: I'm not being flip with a name like "Ding Ling". She was a famous
Chinese author. I do like the name, though ^_^
