Finger picking is a more skill specific technique than that of strumming since it requires more precise connections between the right and left hand. There are a lot of different finger picking patterns and styles. Sometimes you can find easy songs to help develop the basic skill to get started learning. The song “Dirty Paws” from the band Of Monsters and Men is a good example of an easy finger picking pattern to start with. You only need to use your thumb and index finger on a small group of strings as explained in this video. For more extensive work in finger picking I have a course on my website called “Techniques to Master the Guitar”, whether you’re a beginner or have some experience you’ll find specific instruction on finger picking designed to boost your skills.
