In Tomiki Aikido there is a set of techniques called the 'seventeen.' There are few things that are interesting about this set. It is one of the more advanced sets next to the 'koryu' (or as we call it, 'old school') sets. Basically, along with the koryu it forms the real core of the Tomiki style; in the koryu, fighting from kneeling and links between aikido and jujitsu are covered. In the seventeen are the main techniques that deal with dynamic motion and strikes. They are fast, smooth by necessity, and are often easily made into striking combinations themselves. Interestingly, however, is the necessity of ingraining the 'fifteen' (a more basic set) before digging into the seventeen. Without the muscle memory created by repetition of the done-from-static fifteen, the seventeen are unnecessarily difficult to learn and understand. The trouble with this is that the fifteen often seem boring because of their static nature, and their use sometimes incomprehensible compared to the immediately apparent application of the seventeen. But the value of a thorough understanding of those basic principles becomes immediately apparent when the student who paid attention smiles after gracefully clotheslining someone, and the inattentive student throws himself.
