When I was young, I had a teacher who used to tell us that riding simply meant giving the right aid, at the right time, in the right duration, intensity, and in the right combination with the other aids. Sounds easy, doesn’t it? But it’s very difficult to explain or to quantify because every horse and every situation is different. There is no one-size-fits-all formula.
Intensity
It’s impossible to give specific instructions on how many grams or ounces should be in any given aid because horses are living beings, not machines. The appropriate intensity varies considerably from one horse to the next and from one moment to the next. There is no mechanical method or instruction that can help us consistently to find the right amount for each aid. It is a matter of feel.
Every horse’s sensitivity has a response threshold. Anything that is below this threshold doesn’t register, or at least it doesn’t register as a communication.
Every horse’s sensitivity also has an upper limit. When the aid exceeds this upper limit, the horse perceives the aid as a punishment.
So, for each horse there is a “green zone” that exists between the lower and upper limit of sensitivity and tolerance.
It is possible to some extent to move the green zone up or down. For instance, you can teach an unresponsive, “dull” horse to pay attention and to respond to lighter aids. And you can teach a hypersensitive horse to become more relaxed and more tolerant.
This is what we call “tuning” the horse to the aids, just like you tune a musical instrument before playing. Horses that are dull and unresponsive are like an instrument that is out of tune. They are no fun to ride. On the other hand, horses that are hypersensitive are not much fun to ride, either, because they jump out of their skin every time you touch them or if you breathe at the wrong moment. They are stressful to ride because you feel like you’re sitting on a time bomb. These horses can be taught to relax and become more tolerant to the touch.
How big/strong does the half halt need to be?
In order to find out how big or how small the half halt needs to be you have to have a clear picture in your mind of what you want to achieve with it. This is important because you compare the horse’s response to the mental image of the desired result. This tells you whether the aid was successful or not, or whether it was too big or too small.
A good strategy is to begin with an aid that is so small that it is clearly below the horse’s response threshold. Then you increase the aid until the horse notices it and responds to it. If the horse’s response is not exactly what you had in mind, you ask again with a modified aid. When the horse and rider don’t know each other very well, it can take a little time to find out how sensitive the horse is and how he needs to be addressed by the aids. Sometimes horses avoid the aids by getting crooked or blocking them in some way. Then you have to adjust your seat and aids so that you can maintain the alignment of the horse’s body and reach the body part that you are trying to influence.
With a new horse one of the first things we need to find out is how he responds to the aids, and where the response threshold is. One possibility of finding this threshold is to begin very small and then to increase the “volume” carefully.
Another possibility is to guess the right intensity and then observe the horse’s reaction. If the reaction is too small, you can double the aid and observe the response again. If it is too big, you can give a third aid that is in the middle between the first and second aid. This will also be either too big or too small. If you cut the interval between the last two aids in half, you will gradually approach the right amount.
The better you get to know the horse, and the more experienced you become, the more you will be able to “guess” the right amount of the aid intuitively, and the less you have to search for it.
Quality
In addition to the quantity of an aid the quality plays a role as well. This is something that is not usually talked about because most riders do it intuitively, or they are not aware of it, and it is difficult to put into words.
You can give an aid sharply or smoothly, abruptly or gradually, harshly or gently, independent of the intensity. This has something to do with how the aid begins and ends. It also has something to do with the attitude or the energy behind it. You can give an aid that is comforting and soothing, or edgy like a threat. You can overlay all aids with certain emotional or psychological overtones, depending on the horse’s personality and the individual situation. You have to apply your aids differently on a shy, timid horse than on a bold, self-confident horse. And you have to apply the aids differently on a sleepy or distracted horse than on an alert, focused one.
Conclusion
The key to finding the right “tone” in the conversation with the horse is to have a clear idea of what we want to achieve with the aid, to observe the horse’s reaction, and to compare it with the intended result. If the aid didn’t produce the desired response, we have to modify it in terms of timing, intensity, quantity, and quality. And we may have to change our seat and the supporting aids. It’s an ongoing process of fine-tuning our own seat and aids, as well as tuning the horse to our aids.
