(the book)

This is mainly a "how things work" volume, rather than a "how to do it" work. However, the section on transitions between dressage gaits is both how they work and the half halts recommended to produce dressage transitions that are straight, prompt, in stride and fluent.

For the Well-being of all Horses
Olympic winner Klaus Balkenhol and Hans-Heinrich Isenbart demand a change...

If - like us - you believe that
a return to the fundamental principles of classical equestrianism is urgently required,
only a supple horse can perform properly and remain healthy on the long-term,
an appreciation of physical and psychological connections in the training of horses has to be revived,
love of the horse and the aesthetics of equestrian sport should become a focal point once again,
horse-lovers throughout the world should unite in mutual pursuit of these aims. (SEVERAL LANGUAGES)

Attention & Confidence: those foundation qualities of a horse's training that builds trust between partners . . . and how horses use their minds. Included is an iterative, interconnected training pattern as a classical system of riding. This page also includes an iterative version of the training PROCESS that has the CONTENT of linear or pyramid style "training trees." The diagram indicates relations of CONTENT skills to the PROCESS cycles of gymnastic plus mental development of a dressage horse.

Equine Social Intelligence: 12 tests based on the test series that rank canine social intelligence. There are references to other literature, if you wish to pursue animal ways of thinking.

Some thoughts about an iterated training program for riders wishing to adopt an independent spiral seat. The Independent Seat is complex and its dependence on "riding with your core" takes time to learn. It is very demanding of alert relaxation, a dancer's isolations and light, steady connection to a horse.
Classical Training: Self Carriage and Relative Elevation as complex qualities that embrace gymnastic and mental qualities of a horse's development.

Collection and Engagement versus Contraction: a modest proposal about the biomechanics of riding a horse forward to the bridle to create LIGHTNESS...

An illustrated discussion of why problems with transitions lead to a shortening of a horse's outline (tensioned riding with contracted gaits). Collection is based on straightness plus a horse's developed coordination at sustained lifting of its whole spine, or managing its posture (relative elevation). Engagement as increased flexion of the joints of the hind legs is illustrated for canter, along with its conseqences for the horse's forehand posture. Riding dressage transitions as forward, prompt and (at least) level with an understanding of how to achieve their multiple requirements of

•tempo (timing of strides, usually as "strides per minute")
•rhythm (pattern, timing of steps within a stride)
•phase shift of legs (symmetry breaking, passive and dynamic balance) and,
•velocity change

is one key to collection. Another key to collection is a rider's sense of timing for the aids, which requires an independent seat.

•Riding the Elastic Ring and the Elastic Ring structure

On the Contact, On the Aids and On the Bit
The distinction between on the contact and on the bit (preferred term "on the aids") is technically the upward adjustment in posture of the spine that the horse makes in response to the aids, especially those of the rider's lower body. This happens when the contact between rider and horse is continuous through both their bodies. "On the aids" produces a unification through what some authors term "the circle of aids." "On the bit" is a term in common use, but it is a preference of this site to use "on the aids" or "on the contact". This series of pages has images representative of green and schooled horses.

Anatomy with radiographic material on the hyoid apparatus in context of "on the aids" and problems with breathing that may result from holding a horse's neck short. Includes citations from the veterinary literature concerning anatomy of injuries dressage horses experience from being ridden behind the vertical for long periods.

•Adjustment of the Horse's Posture from the Lower Leg
•Yes, there is a Bend and more! There is roll, pitch and yaw. Horses exhibit very complex motions of their spines with each stride: in general, each motion axis is paired with another. For example, lateral bending in the spine is accompanied by some axial rotation. This pairing of movements reflects basic architecture of a vertebrate skeleton. A pair of piaffe in hand movies taken to show the activity of the back are offered here for illustration. Also included is the way dressage judges are asked to talk about flexion and bend. In addition, technical/scientific articles showing direct measurements of the horse's spine (bending is just one motion that a horse's spine makes in three dimensions) are cited at the bottom of each page as well as in the discussion context.
Bending combined with primary position and motions of the spine during each stride are shown with the data for walking and haunches-in (lateral bend, axial rotation, and flexion/extension).

NOTE: It needs to be made very clear that horses do bend and that the essence of this process is the placement of the inside hind under the inside hip so that they do not lean in on circles or when passing corners. Horses that lean through corners do not bend because they cross the inside hind under the body. This keeps the diagonal pairs spaced equally left to right (yes! all bending introduces asymmetry into the L ---> R spacing of the two diagonals). But dressage asks the horse to track with forehand and hindquarters aligned so that they are vertical when on a curved track, in lateral work or in pirouettes.

Bending in the trunk/rib cage is accompanied by some axial rotation (as in the belly swing of the walk). Further, the rib cage system is capable of elastically changing its shape in three dimensions as can be observed from the front, rear and top. This is technically a STEP FUNCTION, a response of a deformable structure to loading (mass/gravity/ potential energy) during limb action and release (kinetic energy) in relaxation or suspension (all four legs off ground in ballistic gaits). During these shape changes, viewers from the side see a compression of the trunk that shortens the measurable distance between the first and last ribs (concave shape) alternating with a lengthening of that distance (convex shape).

Straightness; three kinds of straightness are discussed:

•Straight on lines and curves (hind legs follow front legs)
•Push and carry capacity evenly flow from hind quarters (dependency on throughness)
•Alignment of all sections of the spine (problems include clamping the jaw, tilting head, locked sections of neck or "on the muscle," stiff and hollow sides)

Gaits and Dressage:

Dressage gaits are a very special case from the spectrum of equine movement (diagrammed). This page also has an illustrated outline of a bit of the math that shows how and why the classical masters managed to pragmatically figure out an internally consistent system of riding. Practice, theory and what horses know is a dynamic, evolving system of learning. This system involves "first principles" of timing (tempo) and sequence of legs that define pure dressage gaits and point to the loss of timing in damaged gaits. In addition, true gaits (including pacing, which is a racing gait, NOT a dressage gait even if you are riding a gaited horse - see paragraph below) maintain the legs in special relations to the body's center of mass. These relations are the foundations for forward, fluent and prompt dressage transitions.

So far GAITED DRESSAGE recognizes the following variations concerning Walking Horses for USDF Introductory Level and USEF Training Level through Third Level Test 2: free walk, medium walk, extended walk, flat walks (including medium flat walk), running walk. For Icelandic horses, the tölt is recognized. For Paso Finos, paso corto and paso largo are recognized. Because this is a developing category of classical dressage, there will be changes to this section of the site. I will try to locate dressage trainers and judges who are familiar with gaited dressage. So far, I have judged Tennessee Walkers, Missouri Fox Trotters and Paso Finos in dressage tests. If reader interest is sufficient, I will add a Gaited Blog site.

Transitions in a sampling of dressage tests is HERE.

For the fanciers of gaits other than those for dressage, there is very limited material on this site. However, the graphic from Hildebrand's 1965 Science article is HERE, and it includes all the symmetric gaits (tölt, rack, pace and so forth). I am now working on a supplement to the book that will include gaited dressage.

Riding TRANSITIONS between Gaits

Transitions - (six combinations of ordinary walk, trot, canter) Includes a general explanation of DRESSAGE transitions and how they differ from other sorts of gait changes.
Transitions used to develop collection (movies with balanced dressage transitions and also with transitions on the forehand). Dressage transitions are level in balance, prompt and fluent. Data on this page show the velocities, stride rates for dressage gaits. Transition from trot to canter.

•Some suggestions for working using changes of bend and transitions to supple a horse in canter.
Transitions between trot and canter demonstrate the relation of transitions to tempo and throughness.

Throughness, a brief discussion and a movie or two as food for thought in terms of the relation of throughness to transitions between gaits of the campaign school and the high school. Additional ideas concerning throughness as more than "an unblocked state of the horse's musculature." Throughness is a positive attribute of skill of balance (poise). It is a capacity to maintain orientation in three dimensional space that replaces resistant leaning or bracing on parts of the skeleton. Included here is the trot-canter-trot transition as an example of the complex coordination required for throughness.

Passage and Piaffe
It may come as a surprise to some to understand piaffe as more related to the walk than to the trot. However, a look at the "parallelogram" of trotting and the position of legs in piaffe (foreleg of a diagonal pair at mid stance, hind leg of the pair in braking position) should satisfy doubters that this specific phasing of legs does not occur in dressage trotting. Both passage and piaffe partake of the intermediate zone of limb action of inverted/spring-loaded pendulum behavior.

Three movies with their frames shown in series will illustrate variations in piaffe that the eye misses in "real time." Just because a diagonal pair is repeated (relatively in place) in a dressage movement does not mean it is a trot! Still doubting the relation of piaffe to walk? Here is a Spanish Riding School mini movie with all 26 frames laid out to show limb phasing in piaffe.

Here is another variation on the stepping sequence of piaffe: an Iberian horse. The 34 frames of the movie show times when there are three and four feet grounded. For the Akhal Teke, in piaffe advancing, there are also variations. None of the horses shown here are criticisized: they are only examples. Each movie is cited as to source, so you can see more material if you choose. There are YouTube videos showing riders struggling to teach piaffe as "trot in place." Hmmm.

Placement of saddles so they do not interfere with the cartilage cap of the shoulder blade. In addition, the girth needs to be designed so it does not interfere with muscles at the bottom of the rib cage: these "bottom line" muscles are important contributors to the range of limb movement.
Long and low and other deep work that stretches the horse's spine while advancing the skill of the rider toward developing trust in an independent seat.
Remedial Exercises: some suggestions for repairing damaged gaits and bringing a horse back from illness or injury. Most of the work is unmounted and in walk, the foundation gait for dressage. This section approaches rider and horse coordination combined with relaxed, alert posture as having equal importance. Yes, that means riders need to evaluate their own concepts of contact and coordination patterns, especially for transitions, prior to mounted work. (under construction, not yet available)
