ok this is a great Nirvana song, and its pretty easy to play.

there are two main versions to the song: a powerchord version and
mixture of open and powerchords (which i think sounds better,
I at least enjoy playing this version more)

you can tune ur guitar down one step but no one ever does that.
the song still sounds great in standard tuning.

x- palmute or the note is muted naturally

Interlude ("polly said")- E5

In this song its inportant to transition to each chord smoothly,
just add open stroke to do this. Also, listen to the song for the
rhythm. All of the song is there and it songs great on an acoustic
with light strumming.

have a good one.
