Sol Tangos (Flamenco) — iv – III – II – I
The Andalusian cadence applied to Tangos: a festive binary 4/4 rhythm in 8-beat cycles. In A Phrygian: Dm-C-Bb-A. Mixes Cadencia Andaluza (instrumental preludes) with Traditional Harmony (vocal accompaniment). The characteristic accent pattern falls on beats 1, 3, 5, 7.
Playing in Sol minor
G major is the singer-songwriter's key. The open G, B, and D strings spell out the full G major triad with zero fretting. Add the open high E for a Gadd6 shimmer. Nearly every diatonic chord (Em, Am, C, D) has a comfortable open voicing. G is a beginner-level key on guitar because the open G, B, and D strings form a complete G major triad without fretting a single note, and the open low E adds a rich 6th color. Beginners will find this key approachable since most chords use open voicings with minimal stretching.
Voice Leading
The bass line moves through C to Bb (descending whole step), Bb to Ab (descending whole step), Ab to G (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 G to C by perfect fourth.
Capo Transposition
To play in G using familiar open chords: capo 3 with open E shapes; capo 5 with open D shapes; capo 7 with open C 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
G 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 G 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.
