Blues Op. 74 is a structured exploration of the 12-bar blues form translated into the language of classical keyboard writing. It stands out for its clever synthesis of formal classical motifs and blues-scale improvisation.
The primary challenge is executing the blues-influenced grace notes with crisp, accurate articulation.
Comparable difficulty and character — good candidates for what to learn next.
