Thanks, Polly. This is a song in praise of "My homeland," which from the geographical indications given I take to be south Tyrol. It begins with the claim that the wide world is beautiful, but the very most beautiful part is the homeland. It refers to the source of the Etsch, the river Edige as it is called in Italian. It devotes one stanza to each of the four seasons and the beauty of Tyrol in each, and closes with the observation that heaven will be as beautiful as the homeland.
It is similar to the target song only in praising Tyrol and having a yodel refrain. The words do not correspond, and the meter is different.
A little correction to my solmisation of the melody in the previous message: in the refrain, the _so_ that falls in third place in each line should be followed by a hyphen rather than a space.
