This very popular tango dates from 1903. The English translation of El Choclo is the "The Ear of Corn". The instruments specified are electric guitar & bass guitar but these could be substituted by acoustic instruments. The slur markings appear in the conventionally notated music score but not the TAB version. Players once they are familiar with the music can introduced and apply some guitar techniques characteristic of the instrument - "pull offs" and "hammer ons" - to the melody line. However, it may also be necessary to change some of the TAB positions and strings currently specified to ensure consistency in the playing approach. This is probably quite a challenge for an improver level guitarist but the TAB support should help and the triplet figuration has been omitted. A tempo of 60-66 quarter note (crotchet) notes to the minute is recommended. Ãngel Villoldo (1861-1919) was an Argentinian composer and a pioneer of tango which became very popular from both the music and dancing point of view towards the end of the nineteenth century. It is popular today both in Argentina from where it originates and is a familiar and recognisable music style around the world.
