That dudes approach is similar to mines. What I did with this song was slow the track down to its slowest haha. What impressed me though was the clear tone of Snoops warrior being able to still hear the clear exact note he was hitting at such a slow speed. Try it yourself.
Anyways heres my approach to it after a long time figuring it out.
Note: Bigginners way of explaining it
Key of C
b10-10-11-b10-8-b7-5-6-8-b7-9-8-5-6-8-5~6
Notice the sign ~ on the last two notes? Thats Hammering on but as an option,You can also hammer on the same sets of notes (5~6) but for the other two times used as well as the last. Hope that makes sense
Stay Blessed
