Do Rumbas
iv – III – II – I progression in Do minor
Do Rumbas — iv – III – II – I
Energetic, Latin-influenced flamenco style. Binary 4/4 rhythm with 8-beat cycles like Tangos. Often the most accessible entry point to flamenco guitar. In A Phrygian: Dm-C-Bb-A. Made world-famous by Paco de Lucia's 'Entre dos aguas'.
Playing in Do minor
With no sharps or flats, C major is the theoretical home base on guitar. The open G, B, and high E strings all belong to the C major chord, creating natural sustain. C is a beginner-level key on guitar because the open B and high E strings ring within the scale, and every basic chord uses familiar open shapes. Beginners will find this key approachable since most chords use open voicings with minimal stretching.
Voice Leading
The bass line moves through F to Eb (descending whole step), Eb to Db (descending whole step), Db to C (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 C to F by perfect fourth.
Capo Transposition
To play in C using familiar open chords: capo 3 with open A shapes; capo 5 with open G 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
C 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 C 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.
