This is the intro of a song of mine called Progretango. Why the name? In this song I’ve been strongely influenced by the amazing modern tango composer "Astor Piazzolla", he used to call many of his compositions like that: Libertango, Amelitango, Violentango etc.

This is a progressive approach to tango music (originally written in 2/4), let's talk about meters: Piazzolla started writing tango pieces in 4/4, dividing it in 8/8 and
counting 1 2 3 1 2 3 1 2 (this numbers represent the 8 eights notes and the natural accent should be in every number one of the count, I painted them black so you can recognize ‘em). The first section of the intro is written in 9/4 (5/4 4/4) and I prefer counting like that: 5/4 (1 2 3 1 2 3 1 2 1 2) and 4/4 as I said before ( 1 2 3 1 2 3 1 2 ).

Let’ s talk about harmony, it begins in Bm with a typical cliché (very used in tango music) then it goes to Em, then to Bm again, then to Dm, from there it moves down chromaticaly to Dbm, Cm and Bm, I continue developing the cliché with some meter changes until I get to Cmaj7 #11 then comes the heavy metal section!!(you can also download this song from my profile).

have fun!
