Okay i seethe lesson.
I'm not so sure of the question though but here goes:
Here is the tab to video 1
Index-Medium
S S S S S S S S S S S S S S S S
E||---------------------------9-10-11-10-------|
B||----------------------9-10------------11-10-|
G||-----------------9-10-----------------------|
D||------------9-10----------------------------|
A||-------9-10---------------------------------|
E||--9-10--------------------------------------|
S S S S S S S S S S S S S S S S
--------------------------------------------------|
--------------------------------------------------|
--11-10-------------------------------------11-12-|
--------11-10-------------------------11-12-------|
--------------11-10-------------11-12-------------|
--------------------11-10-11-12-------------------|
etc..
and heres the fingering:
I= index
M= middle (medium?)
Index-Medium
S S S S S S S S S S S S S S S S
E||---------------------------I-M-M-I-------|
B||----------------------I-M------------M-I-|
G||-----------------I-M-----------------------|
D||------------I-M----------------------------|
A||-------I-M---------------------------------|
E||--I-M--------------------------------------|
S S S S S S S S S S S S S S S S

--M-I-------------------------------------I-M-|
--------M-I-------------------------I-M-------|
--------------M-I-------------I-M-------------|
--------------------M-I-I-M-------------------|
etc..
The other videos have this sequence but using different fingers (as described).
the playing "process" should be something like: play index, play middle, lift/prepare index while still playing middle, play index and at the same time lift/prepare middle (to avoid notes ringing together)...then this process cycles..
The fingers not being used don't have to be on the fretboard- but you should avoid letting them "fly away" too far from the fretboard as this is considered "bad practise". Keep your hand relaxed and play slow to avoid this
Does that answer your question? If not, can you be more specific?
