Here are several arrangements to help you play Red River Valley on guitar:
Melody & Accompaniment:
Includes flatpick strumming but can be done fingerstyle as well.
Pattern Picking Accompaniment – Example 1:
Use your thumb to play bass notes on the count of 1 and 3 and your index and middle fingers to pluck the strings (instead of strumming) on the count of 2 and 4.
Pattern Picking Accompaniment – Example 2:
Use this pattern as an easy fingerstyle backup as you sing. The fingering is given as an example in the first measure.
A simple Travis picking arrangement that I played at the beginning of the recording.
An easy arrangement you can play if you prefer flatpicking.
