For this fingerstyle guitar arrangement of this historic American Spiritual song, I used a special technique for the thumb to give more fullness to the accompaniment. Here the thumb must play two strings at the same time, this is indicated by an arrow and the letter "B" (brush). This movement can be a bit tricky at first, but if you practise it slowly you can do it. Learn to play it with free guitar tablature, sheet music, chords and video tutorial.
