Commitment – Harold Vick

Not as funky as many Harold Vick songs, this one is nonetheless very swinging with a classic hard-bop sound. The A section melody has a series of one-measure pickups leading to longer notes; these pickups often contain dramatic leaps. This melodic structure, alternating a static measure with a more active "pickup" measure, continues for much of the 32-measure ABCD form, though less so in the D section. The A and C sections are almost the same, but the B and D sections are different throughout.

Though the key is definitely C minor, the changes occasionally imply C major. After an opening cadence in C minor, the fifth measure begins with a descending series of II-V7s starting on Bm7♭5 and continuing into the B section, where it resolves to E♭maj7 on the third and fourth measures. This is followed by an unexpected Dmaj7 for two measures, and then G7 to wrap the section up; the C minor tonality actually appears in the melody in the sixth measure, over the Dmaj7 to anticipate the G7. The D section begins on Fmaj7 instead of the B section's Fm7; this chord begins a "walk down" with a major sound, but brought back into minor with A♭maj7 in the fifth measure to resolve back to the minor tonic.

There is a coda which extends the end of the melody in a descending sequence, with changes that cycle in fourths; this is followed by a break with a phrase similar to the beginning of the melody to lead to the final chord.
