Here is "Dragon Quest I Symphonic Suite - Unknown World":
A-E-D---
--CBA-GF
GEB-A---
Last E is low, all other notes are high. It's three lines long when a normal town tune is only two, this is to preserve the correct timing of the song. You can try removing/changing around the sustains - to try to make all of the notes fit into one town tune, or you can just use the first two lines. You can remove the GF at the end of the second line to make it end less abruptly if you're okay with just the first six notes, like this:
A-E-D---
--CBA---
If none of these work for you, I can try a different part of the same song, or a different song, just let me know.
