Here is the fingering chart, 0=open, 1=1st finger, 2=second finger, 3=third, finger and 4=fourth finger of your neck hand. The notes are played as follows. E=0, F=1, G=3, A=0, B=2, C=3, D=0, E=2, F=3, G=0, A=1, B=3, and C=4. Use the same fingering on the way back down. It helps if you say the notes as you play them and don't worry about speed, it will come.
