Continuing with my El Choclo syncs, next up is Roberto Firpo (1884-1969). Firpo recorded El Choclo in 1940. His style belongs to earlier times, the Guardia Vieja, pre-1930 thereabouts. Which suits El Choclo just fine, since it is a typical Guardia Vieja composition.
Sections are the top level element of music's form. They are the the large building blocks of tango music, typically lasting around thirty seconds or so. Each section is a unique segment of music, having a distinct musical character.
Tango music has two, occasionally three, primary sections, which we may label “A”, “B”, “C”. Sometimes there is an "Introduction", "Bridge", a short section between two larger ones, or "Coda", a short concluding section.
Usually each section will be played consecutively in order (A then B then C), followed by various other orderings. Typically in tango songs each section is played instrumentally then each is sung, then section A is played instrumentally: A-B-A (vocal)-B (vocal)-A. But there are many exceptions and other possibilities.
Phrases exist within a section.
Composers/arrangers make a very conscious decision regarding form. The order sections are heard greatly effects our sensations and responses as listeners and dancers.
