I recommend getting solid with triads before starting this piece. Try my Thirds: Building Blocks of Triads
If you prefer seeing music notation, here is the Music Notation Version
of this tune. This requires a free viewer. You will be prompted to download if you do not already have it, just follow the link on the bottom of the screen. You can change the melody instrument from Banjo to Contrabass by clicking the key signature button and following the prompts.
This wonderful Baroque tune is in jig time, 6/8, so the bar lines in the AB line builder do not correspond.
Review first the fingerings for triads, then study the bass line to determine which fingerings would fit best.
This is the first "half" of the tune.
