OK, dear mudcatters, this thread is accomplishing good things in that we are learning about some Tyrolean and (thank you for the information, Susanne!) steiermärkisch songs.

I have been thinking how to throw some more information into the ring that might conduce to finding the target song. I mentioned that as I remembered it had a Phrygian modality, but that's only half true. The cognatively meaningful verses are Phrygian, but the yodelly refrain is major. As best I can recall it:

so-la ti ti ti-do re re mi re do re-do ti
so-la ti ti ti-do re re mi re do re-do ti

(Short notes are hyphenated, long notes stand alone; only so and la lie below the finalis.)

And the refrain:

mi do so mi-re-do-ti-re so
re ti so fa-mi-re-do-mi so
mi do so mi-re-do-ti-re so
re ti so fa-mi-re do

(Here only so and ti lie below the finalis.

Perhaps someone will recognize the tune, if not the words.
