I'm Sixteen (Chnam Oun Da Pram Muey)

Standard Tuning (but if you want to play along with the original Ros Sereysothea version 
need to drop all the strings down half a step)

Intro/Fill 1

D|--2-2-0--------------------------------------------------------|

(sort of) Chorus

     Em (1 bar) Am (1 bar) Em (1 bar)        Fill 1

e|---0-----------0---------0-------------------------------------|
B|---0-----------1---------0-------------------------------------|
G|---0-----------2---------0-------------------------------------|
D|---2-----------2---------2----------------2-2-0----------------|
A|---2-----------0---------2----------------------2-0------------|
E|---0---------------------0--------------------------3-2-0------|

That's basically the whole song for the original.  The solos in the Ros Sereysothea 
use the Em pentatonic scale so you can just mess around with those.

The Dengue Fever version has an extra bit which just goes through the cycle of chords below.

    Em  ?   G   A   Am  Em  B

e|--7---5---3---5---0---0---7------------------------------------|
B|--8---7---3---5---1---0---7------------------------------------|
G|--9---8---4---6---2---0---8------------------------------------|
D|--9-------5---7---2---2---9------------------------------------|
A|--7-------5---7---0---2---9------------------------------------|
E|----------3---5-------0---7------------------------------------|

The bit above comes in at about 1 min 37 in the Dengue Fever Version and then again at 
starting on the heavily strummed B chord.

There's also this little fill before the bit above comes in at 2.40, after Fill 1 played slowly.

(All tremelo picked, listen to get the rhythm)
