Watch the Add a Fingerpicking Pattern online guitar lesson by Vicki Genfan from Acoustic Rhythm Guitar Cookbook
Once you have your fingers in position for the first chord, make sure you don't totally lift them off of the strings...the next chords will use the same strings – but with 2 different shapes. You'll need to spend time getting a visual and "body" sense of where the chords sit. Use your dots on the guitar neck as reference points! So work on moving between the first 4 chords before you worry about right hand. This study is in 3/4 time, which is another very common time signature. Make sure if you're counting that you are counting 3 beats in each measure – not 4! Take note that when you play the G chord you'll be using 2 bass notes – one on the 6th string and one on the 4th string...ah, the details!
