Standard string tuning (G,D,A,E) recommended 

1. Nothing too difficult, just make sure you are stamping your 
foot two times per second and that you are counting from 1 to 4 
in time with your foot beat. So in other words, you play the next 
note each time you finish counting to 4.
|—————————————————0—————————————|
|—4———0———2———————————0—————————|
|—————————————4———————————2—————|
|—————————————————————————————3—| 

2. By now you should be able to count to 4 with a steady foot beat 
because you will need to play each note in time with your footbeat.
|—————————————————————————————————0—0—0—0—————————————————————————|
|—4—4—4—4—0—0—0—0—2—2—2—2—————————————————0—0—0—0—————————————————|
|—————————————————————————4—4—4—4—————————————————2—2—2—2—————————|
|—————————————————————————————————————————————————————————3—3—3—3—| 

3. This one is called a walking bass line. Remember to play each 
note in time with your foot, but I'd personally recommend that 
you take your time in being able to get used to playing the notes 
at your own pace so that you could either remember the notes, 
or be able to site read them. Good Luck.
