Concertina - The Mars Volta
Tremulant EP
Guitar tab by Andrés

As we all know, Omar improvises a lot on all of his songs, specially live
Tabbing out all the variations would not only be very complex, but
also futile. If you want to improvise, do your own stuff.
The song is in Dm, so youll find a lot of non natural notes (Eb, Ab, Bb).

About the tab: the song is mostly based on chords, and you can play them
wherever on the fretboard you want. The same goes for the notes on the 
verse. This is the way I like to play it, and regardless the position, I 
think the actual notes are there.
Parts between brackets () are not always played by Omar.

On both of the last bars Omar plays a lot of variations
during the song. I have tabbed out (contrary to what I said
before) some of the variations on the last bar:

The other guitar plays this on the beggining, the rest
is mostly the same. On the ending chord keyboard goes
to Bb, creating a nice harmony
