Categorical Transition Index
A transition is a way of capturing momentum from a landing (of the first trick,) and putting that momentum into a takeoff (of the second trick.) Transitions are identified by observing the connection between landing type and takeoff type; how did the setup end (was the landing on both feet or one/one at a time?) How did the the takeoff into the second trick begin (from both feet, one foot, or one at a time?) The viable combinations of landing and takeoff types can be summarized into four categories of transitions, described below.
A Complex transition represents a connection between a landing on only one leg, and a takeoff from only one leg. This type of transition requires the highest concentration of balance, as it connects from singular (one foot only) landings into singular takeoffs. Examples of Complex transitions include Swingthrus, Misslegs, and Carrythrus.
Simple transitions are the less challenging counterparts of their Complex relatives. These are connections between an ordered landing (one foot at a time,) and an ordered takeoff (the order isn't always the same!) In most cases there is a direct translation from Simple to Complex (or vice versa,) which means those same exact two tricks can be fit together using either category of transition. Examples of Simple transitions are Vanish, Reversal, and Redirect.
Perhaps the easiest to comprehend is a Duplex Transition; a connection from a landing on both feet to a takeoff from both feet. While there are numerous ways to adapt this connection, the only natural (no change in stance or position) form of this type of transition is Punch.
Fitting together different landing and takeoff types produces a Compound Transition. Landing on one foot at a time and connecting to a takeoff from both, or landing on both and connecting to a takeoff from one foot at a time are the two primary ways to execute this type of transition. Examples of Compound transitions are Pop and Reverse Pop.
Common Transition Summary
Below are summarized a collection of popular transitions in alphabetical order, along with a defining characteristic of each. The transitions in the white table indicate that an adaptation has made to the which labels it as "artificial." This is in consideration of the version of the transition which requires no additional change in stance or position; these are found in the gold table and are labelled "natural."
Bound (Compound) - adapted from Punch/Pop/Reverse Pop
Carrythru (Complex) - adapted from Swingthru
Redirect (Simple) - adapted from Reversal
Skip (Complex) - adapted from Vanish
Missleg (Complex) - rebound motion
Pop (Compound) - original Compound transition
Punch (Duplex) - original Duplex transition
Rapid (Complex) - modified Missleg
Reversal (Simple) - reverse ordered connection
Reverse Pop (Compound) - opposite Compound transition
Swingthru (Complex) - linear motion
Vanish (Simple) - consistent order connection
An exciting fact about the limitless creativity in tricking is that captured momentum does not have to continue in the same direction; any transitional movement can be used to change direction at will. Experimenting with fitting tricks together in as many different ways as possible is the best way to understand transitions to their full potential.
*It's important to note that much of the world uses separate terminology for transitional elements. While many of the terms found on Aeriform are commonly used by the international tricking community, it is a good idea to keep communication open and positive when discussing tricks with others who may have different views.
