Basic Tango Rhythm in D Minor

Before attempting Piazzolla's complex harmonies, a guitarist must master the fundamental tango rhythm and the basic Andalusian cadence that underlies most tango music. The classic tango uses the i–VII–VI–V progression (in D minor: Dm–C–Bb–A) with a simple but dramatic rhythmic pattern that gives tango its characteristic urgency. The tango has a 4/4 time signature but its feel is not a simple four-beat pulse. The pattern is "strong-short-long" grouping within each bar, with strong emphasis on beat 1 and a characteristic "flick" on the upbeat of beat 4 (the "anticipation"). This basic pattern is the same whether you are playing classical tango, milonga, or simple social dance music. The D minor Andalusian cadence (Dm–C–Bb–A) appears in countless tango pieces. The A major chord at the end (the dominant) is the key: it uses a major 3rd (C#) instead of the minor 3rd expected in D minor, creating the sharp, biting clash that makes tango sound simultaneously passionate and unresolved.
