Cambalache (Accordion Tango) - Enrique Santos Discépolo

This is a very detailed arrangement of the tango ensemble version of Cambalache by Discépolo.
Since tango is a very niche genre with many subtleties that can pass unnoticed I wrote down many notes on dynamics, fingerings, tempo changes, etc. The YouTube video is a great companion for learning this piece since tango has a phrasing style that can't be clearly translated into sheet music.
