Here you can see and try some fingerstyle exercises using the techniques described on the page How to Play a 12 string guitar..
A number followed by a + sign (e.g.: 3 +) means that it is the octave string alone which is played.
We use the p, i, m, a, notation for the fingers of the right hand:
‘p’ = thumb, and
‘i’, ‘m’, ‘a’ = index, middle and annular (ring) fingers.
P, i, m, a are in fact the initial letters of Latin words and are used pretty universally.
The tablatures will help to visualize the dexterities.

Stage – training
The right handed fingerstyle remains practically unchanged throughout the entire piece. Beware though: in spite of its aspect it is not “picking” style, you must refrain from stressing the thumb. Each note bears the same “weight” : there are no bass notes in this piece, only a high pitched melody. The thumb plays on the octave strings and produces the higher pitched notes – which intermingle with the usual high notes played by the index and middle fingers in order to build the melody. It’s easy and yet quite surprising, don’t you think?
Cathédral – training
Although the right hand play is the same in both cases, the two bars produce vert differen effects due to a mere change in the left hand position. In particular you will notice that the rhythm gives the impression of being twice as fast on the second bar although the right hand hasn’t changed.
The book ‘12 string fingerstyle’ features these exercises and many others.
