La# Tangos Modern Voicing
II – III – II – I progression in La# minor
La# Tangos Modern Voicing — II – III – II – I
Modern tangos voicing documented by Alejandro Roman. Uses Lydian tensions (#11) on the bII chord and dominant 9th on III: Bb(add#11)-C7(9)-Bb6(add#11)-A(addb9). Represents the jazz-influenced evolution of flamenco harmony.
Playing in La# minor
A# (Bb) major requires barre chords rooted at fret 1 on the A string or fret 6 on the E string. Despite the barre demands, it is a common key in funk, New Orleans R&B, and brass band music. The open D string can ring as the major third for added color. A# is a intermediate-level key on guitar because the open D string is the major 3rd of Bb, adding a bright color if allowed to ring. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.
Voice Leading
The bass line moves through B to Db (ascending whole step), Db to B (descending whole step), B to Bb (descending half step). A half-step bass movement creates a strong leading-tone pull that demands resolution. The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from Bb to B by half step.
Capo Transposition
To play in A# using familiar open chords: capo 1 with open A shapes; capo 3 with open G shapes; capo 6 with open E shapes. Choose the capo position that gives you the voicings you prefer — lower capo positions produce a fuller sound, while higher positions create a brighter, mandolin-like timbre.
Scales for Soloing
A# minor pentatonic is your safest starting point because all five notes are chord tones or stable tensions within the natural minor harmony. When a dominant seventh chord appears, switch briefly to A# Dorian or harmonic minor to capture the raised 6th or 7th that the chord implies.
Strumming Pattern
Use D-DU-UDU at 100-120 BPM for a standard pop strum. Accent beats 2 and 4 for a backbeat feel. Vary dynamics between verse (lighter) and chorus (stronger) to build energy.
