E|-------3--------|-------3--------|----------------|----------------|
B|-------3--------|-------3--------|-------4--------|----------------|
G|-------3--------|-----3----------|-------6--------|----------------|
D|---5----------5-|---3----------3-|-----5----------|-------3-----3--|
A|----------------|----------------|---6----------5-|----------5-----|
E|----------------|----------------|----------------|----------------|
