Therefore, numbers such as 'Rokudan no Shirabe' (Music of Six Steps), 'Hachidan no Shirabe' (Music of Eight Steps) and 'Midare' (one of the best-known classical works for so (koto)) are early sohonkyoku (numbers originally created for so (koto), but they can also be played in ensembles with sangen and kokyu).
したがって、「六段の調」、「八段の調」、「乱れ」などは初期の箏本曲（本来、箏のために作られた曲、これらも三弦、胡弓と合奏が可能）である。
