What follows was written by Jon in Kaskade 66:
This pattern is a countdown from 3 - (that is, one round of three-count, then a two-count, a one-count, a two-count and then all over again). As you can see, the name 'countdown' is actually not really appropriate as there is as much counting up as there is down, but what the heck. The countdown from 3 is the shortest of the patterns worth denoting with the dubious term (a countdown from 2 would be a pps). It actually only has 8 throws before it repeats itself, which makes it one-sided (as 8 is an even number). The entire throwing sequence is then psspspps. Some people (myself included) find it easier to remember the entire sequence rather than counting down (and up). I normally think of it as one round of a three-count (that is 'pssp') followed immediately by the reverse (that is 'spps').
To do this pattern warm up by doing
it with 6 clubs. When that feels comfortable pick up that extra club and
proceed to the Copenhagen Countdown.
In this pattern 'Juggler 1' (let this be the best of you if you are not at
the same level - the reason for this will become clear in a moment) starts with
two clubs in each hand throwing the countdown sequence like in the 6-club version
but making his passes crossing floaty doubles. If 'Juggler 1' (J1) starts from
the left hand it will be easier for 'Juggler 2' (J2), (so J1 actually does the
left-handed version of the countdown, while 'J2 does it right-handed. You could
practice the left-handed version with 6 clubs first if you are sure this won't
mess up your partner's head even more as he will then have to learn it left-handed.
The terms 'left-handed' and 'right-handed' are not totally appropriate in this
context as the pattern has two right passes and two left passes, no matter what
hand you start from. However, the pattern is still one-sided since it repeats
every eight beats, and it actually feels a bit different doing the 'left-handed'
J2 has two clubs in his right and one in his left and does exactly what he was doing in 6-club version (starting right-handed), only his passes are (straight) floaty doubles (this will be fairly easy if you have the 6-club version solid). J2 starts one and a half beats after J1, so the timing of the start is exactly like in a 7-club three-count.
But wait! There is more! Because to get this to work J1, gets two 'zips' (aka 'handacrosses' or '1s' in normal siteswap) instead of two selfs. The zips are in the diagram represented by the back pointing arrows. So her entire throwing sequence is pzspsppz (Note: The first zip in the first round should be thrown as a normal self, meaning that the first actual zip is throw number 8). This might all sound very complicated but it is a lot easier than it sounds, as the zips come natural (if you are used to doing zips, that is). It might also be helpful to know that the two zips are both from right to left so J1's right hand will be doing no normal selfs (except for its very first throw) so the her right hand will be starting with a self and then doing pass, pass, zip, zip, pass, pass, zip, etc.
In case anyone is interested, the fourhanded
siteswap for the Copenhagen Countdown is 9629669669969929. J1 does 92696992
and J2 starts one and a half beats later and does 96696996.
OK, enough explanations. Enjoy and remember that this pattern is not so difficult - so if you are an ambidextrous 7-club passer and this seems impossible you are probably doing something wrong.
