I have been learning fingerstyle guitar for a while and I can properly play songs with simple bass lines, but now I arrived to some songs with more difficult bass lines that don't sort of follow the main melody rhythm.
An example would be this song, where the main melody has notes in each eighth but the bass line measure has two notes each 3 eighths and 2 notes each 2 eighths.
Other example can be fingerstyle blues songs that have a constant bass line but melody notes have a different rhythm like here.
Can I have some tips on improving this aspect of the fingerstyle playing? Maybe a book, or a keyword to easily find exercises online to practice this.
