Jim,
Larry carried a stop watch... many a night I would sit there with
Larry and count not only beat/seconds but also how many revolutions
and steps in different swing positions... and compare one dancer with
another's footwork etc..  He loved to break down the dance/movement to
its smallest piece...
I would not hesitate to have a band change tempo in the middle of a
dance if they were ether dragging on or running a race.  The caller
can see what is working on the floor.. and it is about the dance.
On the other hand.. Bob McQuillen will stop a chestnut cold in the
middle of a dance if the fiddler is to fast or two slow.

 The remark to which Martha refers appears on page 37 of _Zesty
 Contras_, in the section V.2 ("Time Management).  Larry writes:
         I know from having recorded many dances that the tempos used
      vary between 30 seconds per change of 64 beats and 35 seconds
      per change.  A lovely average tempo is 32 seconds/64 beats. ...
 On page 42, in his sample self-critique, based on a tape of himself
 teaching and calling "Country Doctor's Reel," Larry describes the
 tempo thus:
      Tempo: 33.8 sec. (average time required for one change).
 I believe Larry preferred to write tempos in terms of seconds per
 change (64 beats) rather than beats per minute because he did his
 timing with a watch--probably a stopwatch--rather than a metronome.
 Perhaps someone who spent more time with Larry than I did could
 confirm or refute this.
 In any case, I believe that a stopwatch is a substantially better
 tool than a metronome for measuring (as opposed to setting) tempos,
 particularly if the stopwatch has a "Split" or "Lap" feature.  This
 is a button that makes the stopwatch display either the current
 cumulative time (since last started) or the time since the last
 split/lap or both, while also continuing to run so that you can
 capture more split/lap times later.  Some watches store split/lap
 times in a memory that you can examine later at leisure.  Sporting
 goods stores typically carry such stopwatches with a variety of
 features, memory capacities, and physical durability (or lack
 thereof).  Nowadays many cell phones have a stopwatch feature
 built in.
 My technique for taking timings is to get my finger tapping
 lightly to the beat on the appropriate button (start or
 split/lap) and then actually follow through and press the
 button on a particular beat, typically beat 64 of the tune
 (or the last beat of the "four potatoes, if I'm timing from
 the start of the tune).  Then I do the same thing at the
 corresponding place in the tune 64 beats (or 128 or 192
 ...) later.  I find that in this way, I can keep my timing
 inaccuracy down to a couple tenths of a second or less most
 of the time.  That amounts to less than one beat per minute
 when averaged over one round of a tune, and less when
 averaged over multiple rounds.  As an example, here are
 results that I got just now by timing the same two repeats
 of a tune on a particular YouTube video five times:
      31.50 + 31.23 = 62.73 (avg. = 31.365 sec/change; 122.4 bpm)
      31.44 + 31.22 = 62.66 (avg. = 31.330 sec/change; 122.6 bpm)
      31.43 + 31.36 = 62.79 (avg. = 31.395 sec/change; 122.3 bpm)
      31.51 + 31.22 = 62.73 (avg. = 31.365 sec/change; 122.4 bpm)
      31.47 + 31.22 = 62.69 (avg. = 31.345 sec/change; 122.5 bpm)
 By taking multiple split/lap times over the length of a dance,
 you can also get get quantitative information about whether the
 band maintained a steady tempo or sped up, and if they sped up,
 whether it happened gradually or suddenly (e.g., at a tune change),
 etc.  Unlike with a metronome there's no need to look at a
 stopwatch continuously while taking timings.  While I've described
 taking split/lap times at intervals of 64 beats (or multiples
 thereof), there's no need to devote much attention to counting
 to 64, since you can let the  phrasing of the tune and the pattern
 of the dance effectively do the counting for you.
 To convert from seconds per change to beats per minute, you can use
 the formula
      # of beats per minute = 3840 / (# of seconds per round)
 The 3840 (= 60 x 64) comes from the fact that there are 60 seconds
 in a minute and 64 beats in one round of a standard-length contra
 dance/tune.  Or you can remember a few equivalences, such as 32
 seconds per round being 120 beats per minute, 30 seconds per round
 being 128 bpm, etc.
 While calling, I find it fairly easy to make a quick assessment of
 the tempo by taking a few split/lap times at 16 beat intervals
 (16 beats/8 sec = 120 bpm; 16 beats/7.5s = 128 bpm; 16 beats/8.5s
 =~ 113 bpm) without distracting much attention from watching the
 dancers.  Such measurements can help me check a visual impression
 that dancers are either plodding or racing and decide whether
 the situation warrants signaling the band to adjust their tempo.

  Alan's answer is the "right" one,
in my experience, but I offer this
 anecdote:
 I used to wonder what the "right" tempo for a contra dance was, so
 any time
 the following three things happened at the same time, I took note of
 the
 tempo.
   1. I was sitting out the dance
   2. I had a metronome handy
   3. The dancers looked really happy dancing
 In EACH of the several cases in which those three things happened
 simultaneously, the answer was, surprisingly, the exact same thing:
 120 BPM
 Mind you, that's just contra, and a smallish sample just in the
 Midwest.
 Because of a square dance tradition in Missouri that sometimes used
 tempos
 up to 144bpm (!) we were occasionally treated (or subjected) to those
 faster tempos and developed a style of dancing that made it
 difficult for
 us to dance any slower than about 112bpm (that's only two metronome
 marks
 away from 120bpm).  Bands from the East coast would come and play at
 104-116bpm, and we would find it hard to stay with the music. In
 recent
 times, the tempos from our old-time bands have slowed a bit, and
 more of us
 have experienced bands from elsewhere at dance weekends - but we're
 still
 happiest at 120bpm, for some reason.
 I also remember reading somewhere in my two Larry Jennings books
 that 120
 was the ideal tempo, but I can't find the reference, so maybe I made
 it up.
 You should also know that, on a slightly different topic, the old-time
 musicians who play for contra dances (around here, anyway) look at you
 mighty funny if you even mention the word metronome or beats per
 minute, so
 don't do it. Do what Alan said - tap your foot, deedle, or better
 yet, keep
 your mouth shut, because some of them have pointedly told us callers
 that
 it's not our job to tell them how fast to play (strange but true!).
 The
 best way to keep the peace with those folks if you want a slower
 tempo is
 to ask them to play a slower tune. That they can, and will, do.
