As often as a new song is introduced, a symbol is erased until the itikaru [is reached]; the song is then ended.
cf. Volume X, pp.114-128, describing the itikaru and the mindiri
wima.
itikaru matja mudana warai tankubana, malka matja kalina
itikaru-song already finished towards morning, symbols already extinguished
when the itikaru song is ended by morning, all symbols [pertaining thereto] are erased
