The middle 4 bars of the Parker blues is also challenging to play. Rather than a dominant chord for the IV chord, it is a major 7th chord and then there is a half-step walk-down of ii-V's that can be tough to navigate. With the use of sequencing, a melodic repetitive cell, also integral to Wes Montgomery's style of soloing, this hard progression can be easier to play.
