After many years of neglecting (avoiding?) this classic tune as done by Bert Jansch, it has finally been completed as accurately as I have done anything. Take a look at Black Waterside, which is done in Dropped D Tuning.
Black Waterside is a traditional ballad made famous by the early English folkies in London in the early 1960s. Bert Jansch's arrangement is the most popular with fingerstyle guitarists. His is done in Dropped D Tuning and includes many embellishments and ornaments that can be challenging.
