As a new caller, I've received lots of advice on this topic, and I want to
make sure I've been doing it right.
I generally try to have an arc of difficulty, starting with an easy dance,
getting gradually harder, peaking around the 2nd or 3rd dance after the
break, then ending with a simple dance as a cool-down. The actual
difficulty you start and peak with is dependent on the skill level of your
local dance. I also try to have a few extra options if I find the dancers
on a particular evening are newbie-heavy or experience-heavy. In my
programs, that generally means having an extra dance in the arc, then
skipping either an easy dance early on (if there are not many newbies), or
a harder dance later on (if there are lots of newbies).
I also put all my dance cards next to each other and try to make sure that
I don't put very similar dances consecutively, and that I have a good
variety of figures throughout the evening.
More experienced callers: feel free to tell me if this strategy is good or
bad.
Cheers,
