This is a fairly simple arrangement, but it effectively captures the melody and does indeed use "Scruggs-style" riffology wherever possible in a tasteful manner to evoke the nuances of Latin-American Bossa-Nova Jazz in as "bluegrassy a manner" as possible.
There are a few places where 'Reno-style' was neccesary in order to keep the melody intact.
Occasional, but minimal Chord-Melody playing, again to keep the melody intact.
I enjoyed working this one out for the banjo...and I believe you will enjoy learning and playing it!
