How to Play A Major Blues on Cavaquinho
Begin by locating A on your instrument and play through the 6 notes of the Major Blues scale slowly, ensuring each note rings clearly before increasing speed.
The A Major Blues scale contains 2 sharps (C#, F#). This scale does not follow a traditional major or minor key signature, so reading from sheet music may require accidentals.

Set a metronome to 60 BPM and play the A Major Blues scale in groups of four notes, shifting the starting note each repetition. This builds muscle memory across the entire scale range. After a week, try improvising short 4-bar phrases using only these notes.
Experiment with simple two-chord vamps rooted on A to let the characteristic intervals of the Major Blues scale come through clearly. This scale is especially effective in southern rock contexts.
