A beatiful piece of classical guitar, mostly fingerpicking through a chord progression (key of A minor).
The song starts with a simple T - 1 picking pattern on the A minor chord.
Afterwards the chord progression is:
A minor - F maj7 - A m6 - F maj7
Use a T 1 2 3 2 1 T 1 Fingerpicking pattern for that, then...
A minor - A m add4 - A minor - A m add9
Use a T 1 2 3 Fingerpicking pattern for that, then...
A minor use T 1 2 3 4 3 2 1 then A minor with T 1 2 3 2 1 T 1
Repeat those 2 chords one more time then repeat the first chord part again...
A minor - F maj7 - A m6 - F maj7
Use T 1 2 3 2 1 T 1 again then afterwards there is a lovely little descending bass line played with the thumb as you descend through the following chords...
A minor - A m add4 - A minor followed by
A minor use T 1 2 3 4 3 2 1 then A minor with T 1 2 3 2 1 T 1 and
A minor use T 1 2 3 4 3 2 1 then A minor with T 1 2 3 4
After that the tune gets a little more freestyle in places, using C major chord shapes and some little melodic licks, but essentially the song repeats the sections already outlined above.
