This is a pretty little ditty. Simple, yet could prove tricky. Enjoy!
Guitar 1 NEEDS to be an acoustic, or it will sound completely wrong. Harmonics normally sound terrible on Powertab, but if you play this out they should sound fine. It's all a matter of fretting the sounded notes in a way so you can hit the harmonics also. Also, fingerpicking sounds best, but it's harder to strike the harmonics without a pick, so I wouldn't recommend it. As for guitar 2, it's just the ambient hum that exists throughout the song. Not necessary, but it adds a little spice to what might otherwise be a fairly dull-sounding tab.
Not bass notes, since there is no bass...
I have no clue what this was released on. And I have looked. It was probably a compilation of some sort.
