Si Si is a bebop-flavored jazz blues in F by Charlie Parker. It was recorded in 1951 during the same session that produced Blues for Alice, featuring Red Rodney, John Lewis, Ray Brown, and Kenny Clarke. The melody sits in a blues form but includes a striking dissonant moment in the second bar, where the notes E natural, C sharp, and A natural create tension before returning to diatonic material in the third bar. This tune, like Parker’s other blues, showcases melodic, harmonic, and rhythmic innovations that reveal his approach to the blues. The exact album release for Si Si isn’t specified in the provided content, but it comes from Parker’s 1951 blues sessions alongside Blues for Alice.
