Ataka and Kajincho

The main difference I see between the nō play Ataka and the kabuki  Kajincho, is that in Kajincho, there are singers that interrupt the actors as Benkei and his men talk to Togashi, for example when the guards are questioning Benkei and his men.  In  nō, the actors interact in dialogue just between each other, while in kabuki, a phrase that would be said by the actors, is taken and sang by professional singers. (i.e. not the actors in kabuki).  However, these professional singers also act like the chorus in nō which provide a similarity between nō and kabuki.  Each time the chorus (nō ) or singers (kabuki) sing, it adds to the drama of the play.  For example, at the end of the fifth dan of Ataka, the chorus and and the singers are functioning in the same way (pgs 94-95).  "Oh, all you guardsmen,/ what are the reasons,/ Oh, all you guardsmen,/ what are the reasons,/ that you draw the swords and blades/ against so lowly..."
