Groove Merchant: Jazz Ensemble Conductor Score & Parts

Rich Sigler's arrangement captures the infectious pocket of a gospel rock groove without sacrificing ensemble musicianship. The written-out solos for trombone and trumpet give inexperienced improvisers a scaffold to build from, while the clever modulations and development section reward groups ready to dig deeper into the form and phrasing.

Groove Merchant swings with a contemporary gospel-rock energy that feels alive and present. The arrangement invites the ensemble into a pocket groove while offering enough harmonic and melodic sophistication to keep rehearsals engaging and performances memorable.

Medium-easy jazz ensembles and young jazz programs seeking a chart with real substance and contemporary feel. This works for groups confident enough to handle written solos but not yet ready for fully open improvisation.

• Lock the rhythm section (bass and drums) into the pocket at 132 BPM before adding the horns; the straight eighths and gospel feel demand precision and confidence from the foundation.
• Have the lead trumpet isolate the written high passages that reach G on top of the staff; balancing that range with the rest of the section takes rehearsal time and breath management.
• Give soloists space to breathe within the written-out parts; treat the trombone and trumpet solos as points of focus that deserve ensemble support and careful listening from the rest of the band.
• Explore the modulations intentionally so the ensemble hears them as compositional landmarks, not harmonic detours; they shape the arc of the chart.

Program this as a centerpiece for a jazz concert or festival set; its three-and-a-half minute duration and accessible level fit comfortably alongside more traditional big band charts. The optional vibes part opens doors for percussion students who want expanded ensemble roles beyond drums and bass.

• Reading lead trumpet range and balancing extreme highs with section blend
• Pocket rhythm playing and straight-eighth articulation in a gospel-influenced groove
• Following written-out solo forms with harmonic awareness
• Recognizing and responding to modulations within a single arrangement
