is a style of sword-drawing art (iaido) founded by Nakayama Hakudà  (ä¸Âå±±åÂÂéÂÂ) in 1932. Nakayama Hakudà  studied under Hosokawa Yoshimasa, a master of the Shimomura branch (ä¸ÂæÂÂæ´¾) of Hasegawa Eishin-ryà «, and Morimoto Tokumi, a fellow student of à Âe Masaji of the Tanimura branch (è°·æÂÂæ´¾). The name Musà  Shinden-ryà « most likely comes from the name given to the Shimomura branch by Hosokawa, Musà  Shinden Eishin-ryà « (ç¡éÂÂç¥Âå³è±信æµÂ).
The kata from Musà  Shinden-ryà « have a number of differences from the kata of its sister art, Musà  Jikiden Eishin-ryà «. Among the most visible are the manner in which the furikaburi (raising the sword overhead, sometimes called furikamuri) and the nà Âtà  (sheathing) are done. Both arts also differ from many other iaijutsu schools in that the kiai is performed silently, without hassei (shouting).
After striking with one hand, primarily on nukitsuke (cutting as one draws the sword out), the sword is brought to a position about ten centimeters above the left shoulder, blade edge up, and with the point facing backwards. The movement resembles a thrust to the rear. Unlike in Musà  Jikiden Eishin-ryà «, the sword does not fall off behind the back but always stays over shoulder height. The right hand then raises the sword overhead while the left hand takes its place on the hilt, thus entering in the jà Âdan stance or kamae. The sword should now be right in the middle line of the body, with the tip raised forty-five degrees upward (Chuden) or level with the ground (Shoden) and your left hand hovering just above your forehead.
In Musà  Shinden-ryà «, the sheathing is performed horizontally with the blade outwards. In Shimomura-Ha lignage, more usual, only when the sword is about two-thirds of the way in the saya is the edge turned to face upwards, but there is also a Tanimura-Ha lignage inside Muso Shiden Ryu, and the sword is in the saya is the edge turned to face upwards. The blade and saya should cross your center line at a 45-degree angle while sheathing.
The word "Shoden", which can be translated as the "first transmission", consists of the kata of à Âmori-ryà « iaijutsu plus one kata variation exclusive to Musà  Shinden-ryà «. The kata start from the seiza sitting posture. This series of kata became the first to be learned when the 17th headmaster of the Tanimura branch, à Âe Masamichi, reorganized and rationalized the curriculum of Hasegawa Eishin-ryà « at the start of the 20th century. The kata Ryà «tà Â, which involves the Ukenagashi technique, is often considered as the most difficult kata of the Omori set. The seventh kata, Juntà  was created neither for dueling nor for self-defense, but to serve as kaishakunin.
According to his own memoirs, Nakayama Hakudà  invented the twelfth kata, In'yà  Shintai Kaewaza, as a variation on the fifth kata In'yà  Shintai.
The following is the order given by Yamatsuta. In some schools, the order of the last two kata are reversed.
The word "Chà «den" can be translated as the "middle-transmission" and consists of ten techniques from Hasegawa Eishin-ryà «. This series of kata is executed from the tachihiza (more commonly called tatehiza) sitting position. In contrast to the first series of kata, the enemy is considered to be sitting very close and thus the primary goal of the chà «den techniques is to create proper cutting distance (kirima) by stepping back instead of forward.
à Âe Masamichi is credited with developing the hayanuki (quick draw) exercise. In this style of training, the practitioner executes all ten techniques in a row. Two versions of hayanuki exist. In one version, both the left and right hands are used to execute the movements, just as in the normal practice. The second version involves drawing the sword with only the right hand, as if you were on a horse. This kind of practice is not done in formal presentations.
The word "Okuden" can be translated as the "inner transmission". Oku-iai, as it is also called, is divided into two groups: suwari-waza (sitting techniques) and tachi-waza (standing techniques). As in Chà «den, the sitting techniques are performed from tatehiza.
Suwari-waza (座æ¥Â)
<nowiki>*</nowiki> Despite the fact to be a sitting-form, in an Enbu the Itomagoi form is usually performed after the execution of all standing forms so the kenshi is ready to begin the finishing reiho, like Battô in Omori-ryu and Nukiuchi in Hasegawa Eishin Ryu.
Tachi-waza (ç«Âæ¥Â)
<nowiki>*</nowiki> This is believed to be a kata that Oe Masamichi Sensei discarded when he re-organized the old tradition. It is generally not performed.
The paired Kumitachi techniques (the kenjutsu part of the curriculum) are rarely taught today. Tachi Uchi-no-Kurai and Tsumeiai-no-Kurai are the series most often taught.
