[Callers] Tempos for Contras (was Re: Tempo for Squares)

On Sep 21, 2019, at 1:14 PM, I (jim saxe <jim.saxe(a)gmail.com>) wrote, in response to Rich Sbardella's question about tempos for (New England) squares vs. for contras: To illustrate the difficulties of gathering solid data on such matters, here's a report on an attempt I made back in 2012 to gather some data about tempos for contra. I'll first give a rough description of my methodology, as best I remember it, then a tabulation of the data, and finally some comments, including speculation about possible flaws, limitations, and unanswered questions. I think it will be obvious that the similar comments might apply to any proposed attempt to gather information about square dance tempos. * * * * * * * * * * * * Methodology: To gather some data on contra dance tempos, I decided to time a bunch of YouTube videos of contra dances. I typed "contra dance" (in quotes) into the YouTube search box and looked at the results in the order they we presented, but excluding some for various reasons, as described below. To measure tempos, I used a stopwatch capable of taking multiple "lap" (a/k/a "split") times. My procedure was to start timing at the last beat of A2 in the first repeat of the dance/tune (or the earliest place I could identify a "last beat of A2" in videos that started partway through a dance) and then to press the lap/split button at the last beat of A2 in various later repeats of the tune. Given the time interval between two such corresponding beat in different rounds of a 32-bar (64-beat) tune, it's a matter of simple arithmetic to estimate the tempo. By starting and ending my timings at end of A2, I avoided timing the ritards that bands sometimes play near the end of B2 on the last round of a dance. I also avoided dealing with the question of whether bands really play the first beat of A1 just one beat-time after the last beat of a four-beat intro. Because I wanted to get accurate tempos despite inevitable slight inaccuracies in the timing of my button pushes, and because I wanted to investigate whether bands tend to speed up or slow down over the course of dance, I excluded short videos. In particular, I didn't include any video where I couldn't time an interval of at least 10 x 32 bars. If I recall correctly, I also excluded videos of total length under seven minutes. As a result many of my timing go from the middle of the very first round of a dance to the middle of the very last round. There were a few other videos I exclude besides ones that I decided were too short. I don't have a complete record of the reasons, but I think there were some that had cuts instead of being recorded in a continuous take, and there was at least one and maybe more where the sound quality and/pr the nature of the music was such that I couldn't feel confident of taking accurate timings. If I came across something like an hour-long documentary about some festival or dance camp, I would not have bothered listening to the whole thing on the chance that it would include a 10+-round continuous segment of a dance. I may also have excluded additional videos from Concord, MA, after including five of them. * * * * * * * * * * * * Tabulation of timings: I timed a total of 40 contra dane videos before I ran out of steam. I list the reuslts below in increasing order of averqge tempo. Each line of the list has the form: AV_TEMP (START_TEMO, END_TEMP) YT_ID LOCATION; STAFF where AV_TEMP is the average tempo over the full interval timed (at least 10 x 32 bars) START_TEMP is the average tempo of the first 4 x 32 bars timed END_TEMP is the average tempo of the last 4 x 32 bars timed YT_ID identifies the YouTube video. Prepending "https://www.youtube.com/watch?v=" will give the full URL. Note, however, that some videos may have become unavailable since 2012. LOC identifies the city (if known to me) and state or province where the event in the video occurred. It occasionally also includes a parenthesized note identifying a special event.

I believe that the difference between a tempo of 111 and 128 would feel quite substantial to dancers. The parenthesized numbers suggest that bands tend more often to speed up than to slow down. There are, however, several cases where they slowed down, and even a few cases where, unless I made some kind of error, they seem to have sped up a little and then slowed back down or vice versa, so that number in the first column isn't intermediate between the parenthesized numbers. Given the substantial spread of tempos and the relatively small number of videos I've timed, it seems hard to draw strong conclusions. It's also possible that my sample is inherently biased, for example over-representing special events and dances in larger communities, since those may be the events most likely to have people taking videos and posting them on YouTube. I haven't seriously investigated possible relationships between tempo and tune types (marches vs. jigs vs. reels), time of day/evening, geographic region, age mix of the dancers, inclusion (or not) of squares in local mostly-contra events, the temperature and humidity of the hall, etc. For example, I've heard that contra tempos tend to be higher in the midwest (perhaps due to historical influence of the regional old-time music scene) than in some other regions. A brief skim of the tabulation above mildly suggests that that may be true, but I don't think there's enough data there to draw that conclusion with strong confidence, much less to accurately quantify average tempo differences between and within regions. I think that reaching clear statistically-supported conclusions would require a larger sample set of videos and more thought about how to ensure that the sample isn't biased in a way that might make it seem to indicate a correlation of tempo with region when it's really indicating something else (e.g., the existence of one very active local videographer who likes to go to dances with bands that have a reputation for playing fast). Raw data about things like age demographic of particular dance communities or temperature of particular halls on particular evenings could be hard to gather. I also haven't investigated whether contra tempos have, on average, sped up, slowed down, oscillated both ways, or stayed about the same over any particular period of years (or decades), either (inter)nationally or in any locale. In such an investigation, one might want to use old cassette recordings made by dancers, but one might not be able to trust that playback speed (possibly on different equipment) is really the same as recording speed. --Jim
