The postural stability of the horse stance takes away the need for a lot of the upper body adaptations that can affect the neck and shoulders. Combined with an efficient breathing pattern that doesn’t load your secondary respiratory muscles it’ll allow you to lose a lot of the myofascial tension in your upper body.
In horse stance your lower body is stable and it’s easier to bring your breath down into your lower abdomen:
Another breathing exercise
The advantage of modelling our relaxation program on tai chi training is that it teaches us to be at the same time, relaxed and keenly focused, ready to strike. This exercise, sometimes used as a warm up in tai chi class, begins the process of incorporating movement with our breathing/relaxation exercises.
Your lower body needs to be solid but not stiff, allow it to move slightly up and down with your breath as well. In this exercise you are localising the relaxed sensation to your shoulders and upper chest, which is where you want it when you’re playing.
The key to this exercise is the out breath. Rather than actively bringing your arms down, simply allow them to fall. If you can tune in to the sensation of falling as your arms come down you’ll have got what you need from this exercise. You need to recall this sensation of letting go every time you see the word ‘relax’.
