Tango and the fitbit! Bear with me…
A typical tango is structured as follows:

  1. There are 5 Sections often called ABACA*.
  2. Each of the 5 sections has 4 phrases.
  3. Each phrase consists of 4 measures.
  4. Each measure has 2 strong beats (1 & 3).
  5. Therefore each phrase has 8 strong beats.
  6. So each section has 32 strong beats.

Thus a whole song with the ABACA structure has 32+32+32+32+32 beats.
32×5 = 160 i.e a typical tango will take you 160 “steps” to complete
if you step on all the strong beats.

If you go a milonga which has a tanda structure of 4 tangos, 3 Vals, 4 Tangos, 3 Milonga with a cortina of half a minute between each track the 1st round of this structure will last an hour as follows:

  1. There will be 4 tandas of tango at about 10 minutes each giving a total of 40 minutes.
  2. There will be 1 tanda of vals at about 8 minutes.
  3. There will be 1 tanda of milonga again at about 8 minutes.
  4. This gives about 56 minutes of dancing.
  5. Since we know a step takes 1 second (ish) you will step 56×60 if you dance all the songs.
  6. 56×60 = 3360 steps.

So if you go to a 3 hour milonga, dance all the tracks you will step 3360×3 = 10,080 steps.
i.e you can complete the typical 10,000 Fitbit target in one 3 hour milonga!

Each step lasts about 1 second depending on the tempo or speed of the music. Since a strong beat lasts about 1 second it takes 160 seconds or 2 minutes 40 seconds to complete the song. This is why most tangos take 2.5 to 3 minutes. Take 1 song “La viruta”:

D’Arienzo 2.18
Canaro 2.25
Tipica Victore 2.57
Di Sarli 3.03
Fresedo 3.30
