Since I’ve added the ability to set the tempo of a dance for a song independently of the tempo of the song itself, I’ve found some renewed energy to go through and clean up some of the inconsistencies that have crept into the music4dance catalog. As I promised (or threatened) when I blogged about the update, I am going to share some of the fun rhythms I find in this process.

12/8 Rhythm

The first “fun rhythm” I’d like to talk about is 12/8. This is effectively 4/4 time where each beat of 4/4 is a triplet, although technically it’s twelve eighth notes per measure (4 *3 = 12)

This post on Jade Bultitude’s site does a much better job of explaining and illustrating the musical part of this than I do.

Dancing to 12/8

The fun thing about this rhythm is that as a dancer you can count it in two ways – either as a 3/4 measure for each of the triplets or as 4/4 where you hear each triplet as a beat.  Then the triplet rhythm will sometimes work for a Viennese Waltz, and the 4/4 rhythm will work for a slow dance like a Slow Foxtrot, Nightclub Two Step, or Blues.

Examples

“Like I’m Gonna Lose You” by Megan Trainor featuring John Legend is listed as West Coast Swing, Castle Foxtrot (e.g. Slow Dance), and Blues at 72 BPM, and Viennese Waltz and Tango Vals at 216 BPM on music4dance. The sheet music shows the tempo as 72 BPM, so I’ve set the main song tempo to that.

The sheet music for “Me and Mrs. Jones” by Michael Buble shows that it is technically in 6/8, but the same principle applies. The music4dance page shows votes for Viennese Waltz at 198.2 BPM and Castle Foxtrot (e.g. Slow Dance) and Slow Foxtrot at 66 BPM (this would be very slow for Slow Foxtrot).

Cataloging

I am still playing with how to tag these kinds of songs. Should I add a 12/8 tempo tag to the songs (*even if they might be technically 6/8 or 4/4 with strong triplets)? Should I put a 3/4 tag on the Waltzes and 4/4 on the Foxtrots, or is that redundant? Would it make sense to put a Compound Time tempo tag on all of these?

Next Steps

I’m going to continue to muddle through manually cleaning up these songs, but it will take some time, since there are a lot of these (and I haven’t even gotten into some of the other fun variations).

If you’re interested in seeing more examples and/or jumping in and cleaning them up, here are a few interesting music4dance searches:

• All songs that have a 12/8 tempo tag
• All songs that are voted as both Waltz and Foxtrot
• All songs that are voted as some kind of Waltz, but also have a 4/4 tempo tag (and exclude the Fake tempo tag on Waltz) – this one is the gold mine – and headache – there are hundreds of these apparently contradictory songs, many are just cases of the tempo algorithm incorrectly identifying a 3/4 song as 4/4 (and then almost always screwing up the tempo). But some are the kind of 12/8 variation that we’re discussing here. And there are even a few that are even weirder, but I’ll save those for another day.

If you are interested in helping, but find the documentation (or the discussion above) too confusing, or if you have thoughts on how to better tag these kinds of songs, please feel free to reach out with questions or comments.

Step of the Month

Please share an unusual rhythm song (or songs) that you enjoy dancing to. It doesn’t have to be 12/8 or in any way related to the discussion above, just something that’s a little different that you enjoy. Post it in the comment thread here or send feedback.
