Sol Alegrías
I – V7 – I – IV – I – V7 – I progression in Sol major
Sol Alegrías — I – V7 – I – IV – I – V7 – I
Joyful flamenco palo from Cadiz in major mode. Unlike most flamenco which uses the Phrygian mode, Alegrias lives in pure major tonality (typically E major). The 12-beat ternary cycle with accents on 3, 6, 8, 10, 12 shares the solea family rhythmic structure but with a bright, celebratory character.
Playing in Sol major
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 G to D (descending perfect fourth), D to G (ascending perfect fourth), G to C (ascending perfect fourth), C to G (descending perfect fourth), G to D (descending perfect fourth), D to G (ascending perfect fourth). The root motion by larger intervals (fourths and fifths) gives each chord change a strong, decisive character. When the progression loops, the bass returns from G to G by unison.
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 major pentatonic works because every note is either a chord tone or a safe passing tone — there are no avoid notes. For soloing, this means you can play freely without clashing. Over dominant seventh chords, G Mixolydian adds the flat seventh for an authentic blues-rock edge.
Strumming Pattern
Try a D-D-DU waltz pattern at 80-100 BPM. Accent beat 1 strongly and keep beats 2-3 lighter. For fingerpicking, use a bass-pluck-pluck pattern with alternating bass notes.
