Alto padre no’ ti preghiamo Ba6/4?:8/9 (wxyxzx aaaa bbbb...)

note: lauda text in Rs424 without cc. indication. The poem is also transmitted in the (probably) pre-15thc. ms. BML, Ashburnham 423, 39v, where its form appears to be a six-line refrain (abcbdb) followed by a series of quatrains of varying line-lengths (aaaa bbbb...).
