Commands

Command with a fall - Firm, authoritative

The default tone for commands is the definitive fall:

▸Stop that ⤵noise!
▸Tell me the ⤵truth.

Command with a rise - Routine, friendly

In short commands (as with statements) a rise is often used to encourage the other speaker to continue:

Command with a fall-rise - Urgent, warning

For warnings we often use an implicational fall-rise:

▸Watch ⤵⤴out!
▸Wait for ⤵⤴me!
The implication here is something like this:
▸Do as I ⤵⤴say, | or ▸something ⤵bad will happen.
If said with a fall tone, these would indeed be not so much warnings as straight-forward commands:
▸Wait for ⤵me!
▸Do be ⤵careful.
Like negative statements, negative commands often have a fall-rise without necessarily implying a warning:

▸Don't start until you're ⤵⤴ready.

Commands said with the interested rise (with a high prenuclear pattern; see

5.8
) sound soothing and kindly. We use this tone when speaking to children, for example. To adults, it can sound patronizing.
▸Come to ⤴Daddy.
Now ▸take your ⤴time.

Summary

The differences in these tone meanings can be seen when we compare them on the same sentence:

Now ▸move a⤵long, please (firm, authoritative)
Now ▸move a⤵⤴long, please (urgent, warning)
Now ▸move a⤴long, please (routine, friendly)
