Beatmap - A Complete Guide - Part OneLuke Burrage - 1st January, 1990. The Rules
Confused? Let’s go right back to the very beginning, but keep these rules in mind.
BeatsA pattern is made up of one or more beats. Each beat is contained in a set of brackets like this {a beat} Simple patterns with only one, two or three fields per beat can be arranged on one line like this: {beat1}{beat2}{beat3}{beat4}
{beat1} Unless stated, a pattern is repeated. {beat1}{beat2} repeat all
{beat1}{beat2}+ don’t repeat
{beat1}{beat2}+ catch all the balls and stop
{beat1}{beat2}+ go to the next line
FieldsEach beat is made up of one or more field. A comma divides each field. {field 1, field 2, field 3} Often fields can logically be grouped together. The most obvious and common case is the left and right hand of a juggler, the basis of most juggling patterns. This creates a pair of fields, something very handy for notating patterns more clearly and easily. {left , right}
{pair 1, pair 1| pair 2, pair 2}
{pair, pair| single | single} So if a field isn’t a juggler’s hand, exactly what can it be? Fields can be split into three generic types:
Note that the fields by themselves never indicate action. A field isn’t assigned “move the hand to the left” or “turn 180 degrees”. Instead they are motionless snapshots of where a juggling prop, a hand or the juggler may be at a single point in time.
If the pattern that is being described only concerns itself with throwing and catching with the two hands of one juggler, only two fields are required, {left hand, right hand}. But if the pattern being described involves a complex series of backcrosses and reverse backcrosses, six fields may be required, {left hand, right hand | left hand in front, left hand behind | right hand in front, right hand behind}.
Instead, the fields should be as general as they need to be to communicate the pattern in the simplest way, but no simpler. A 3 ball pattern that uses two hands and 3 columns of air can be described fully with 5 fields, {left hand, right hand| left | center | right}. As long as the props, hands and body follow the given notation exactly, the juggler may do anything else he or she wants to, move about, throw and catch in different ways from different positions, etc. Any field not described in a pattern may be improvised.
Ordering and Labeling FieldsThe fields can be arranged within a beat in any order, as long as this order stays constant throughout the whole pattern. A good guide is to always start with the hands (manipulators), then the position of the hands (airspaces), then the position of the juggler or jugglers (orientations). Every pattern has a key. The key says how each field is assigned and also must show, where needed, a unique label in each field. This unique label should be a single, capital letter but in some cases combination of letters may be used. In simple patterns the following keys are used and assumed: One juggler, left and right hands: {L, R} or {A,B} Two jugglers, starting with jugglers left hand and working anticlockwise: {A, B | C, D} Three jugglers, starting with jugglers left hand and working anticlockwise: {A, B | C, D | E, F} And so on. Of course all of these can be swapped easily, with the right hands becoming left hands.
For example, before describing a pattern that involves bouncing or catching a ball on the head and foot the key may be: {L , R | H head | F foot}
(A, B | C, D | F foot | G ground}
{L, R | G outside, H inside | J inside, K outside}
(L , R | N facing north, S facing south}
{left, right | outside, inside | inside, outside} The reason for this will become apparent later.
Two Shortcuts for Pairs of FieldsAn asterisk “*” at the end of the pattern means, “repeat the pattern with all the information swapped to the other field in each pair of fields”. An asterisk does not always result in valid pattern but when it does it can cut down the length of notation by half and give a very clear sign that the whole pattern is symmetrical.
This: {do this, do that}*
In turn this: {do this, do that | and that }*
{~this hand, is crossed over this one} This is a very handy shortcut for notating juggling patterns where the hands cross, such as Mills Mess and Burkes Barrage.
ObjectsDepending on what kind field it is noted in, an object can be different types of things.
Objects are noted in fields as numbers. If a field is empty it MUST contain a zero. An empty field (an empty hand): {0}
{1}{1}{1}{1}+
{11}
First you can use the label of another field. Moving an object from field A on one beat to field B on the next beat, and then back, can be achieved like this: {1,0}{1B,0}{0,1}{0,1A}
{1,0}{1x,0}{0,1}{0,1x} And can now be written as so: {1,0}{1x,0}*
{1x,1C|1x,1A}
{left hand, right hand | left hand in front , and behind | right hand in front , and behind}
{1x,0|1,0|1,0} Or just:
{1x,0|1,0|1,0}
{juggler a facing juggler b, a facing away from b | a standing far from b , a standing close to b}
{1,0|1x,0}{1x,0|0,1}+
Throwing ObjectsAn object can leave a field and return to it without being noted in any other field. Simply put, a ball can be held, thrown and caught again: {1}{2}{0}{1}+ A “2” must leave that field, it must have an airtime of at least one beat, and it must be noted in the same field two beats later. A “3” must have an airtime of at least two beats and be noted in the same field three beats later. And so on. An object’s throw value may also be modified with an “x” or the label of a different field to direct it elsewhere.
{2x,1}*
Part two contains examples of all types of traditional and popular juggling patterns showing the power of beatmap as a juggling notation tool. It also contains ways to connect patterns that use different fields and objects. Part three contains many techniques to manipulate beatmap patterns and the new patterns that are created.

For those of us who "play by ear" but can't read music, it would be nice to see animations of each example. I still have the same visualization problem with siteswap. I can tell you what everything means, and I can juggle a few siteswap patterns, but a bunch of numbers is still just a bunch of numbers until I see it juggled and can break it down one bit at a time. 10th Dec 2004 Oh cool! I thought I'd read al... Oh cool! I thought I'd read all your stuff on beatmap, but I hadn't seen you post this on rec.juggling before. Maybe I missed it. Anyway, it's a much easier introduction to the concept than the exam question one. Good work Luke. Tom |
