How to Play G Prometheus on Cavaquinho
Begin by locating G on your instrument and play through the 6 notes of the Prometheus scale slowly, ensuring each note rings clearly before increasing speed.
The G Prometheus scale contains 1 sharp (C#). This scale does not follow a traditional major or minor key signature, so reading from sheet music may require accidentals.
Practice Routine
Practice the G Prometheus scale by playing it ascending with one rhythmic feel (straight eighth notes) and descending with another (swing or triplets) at 100 BPM. This dual approach trains both technical accuracy and rhythmic versatility with the 6 notes of the scale.
Experiment with simple two-chord vamps rooted on G to let the characteristic intervals of the Prometheus scale come through clearly. This scale is especially effective in experimental contexts.
