About A Blues on bass
The A Blues on bass is one of the most rewarding scales to learn early. The scale's character is gritty, expressive, and unmistakably American, which is why it shows up in so many genres. The notes are A, C, D, D#, E, G, ascending from the root, and that exact sequence is the entire scale.
On bass the blues scale powers the classic walking bass line; the flat-five is a chromatic passing tone between the fourth and fifth. What makes it sound like itself is the gap pattern between notes; transposing to A keeps that pattern intact. Use the highlighted positions as a starting point; once they feel comfortable, try improvising over a simple drone in A.
