This is a kinda Spanish/Mexican song.
If you don't know the tune by name, you should
know it when you start playing it.
*It's the theme of the toshiba add if that helps* 

The whole tune is only played on 1 string (sounds best on medium - low pitched strings).

0-3-5-8-5 |

On those lines, move your finger around when you play the 8 so that it goes wo-ow-ow (i can't remember what it's called lol).

5-7-7-7-7-7-7-12  | (make sure you play a 12, not a 1 then a 2!!!)

Enjoy!
