Up Jumped Spring: 3rd Trombone

Jeff Jarvis's arrangement transforms a classic into something fresh by reframing the jazz waltz in a grooving 4/4 Latin-pardido setting. The chart sits at Grade 3.5 with genuine solo opportunities for your lead players and a sax soli that gives voice to your section, making it rewarding to conduct without sacrificing playability.

Warm and sophisticated, with a groove that sits deeper than a traditional jazz waltz. The Latin-pardido feel gives the piece a relaxed urgency, while the sax soli and optional vibe create moments of lush texture that reward careful listening.

Jazz ensembles in the intermediate-advanced range that can handle the Latin groove and solo responsibilities. Your lead trumpet, tenor 1, and trumpet 2 need confidence and voice; your rhythm section needs to lock onto the half-note pulse without rushing.

• Establish the Latin clave feel early in rehearsal. The shift from traditional jazz waltz character to 4/4 groove is the chart's signature move, so lock the rhythm section on the half-note pulse at 77 BPM before layering in horn lines.
• Give your tenor 1 and trumpet 2 soloist space to develop their written solos during individual practice. These aren't vamp-over moments; the provided melodies give shape to the improvisation and reduce anxiety for less experienced soloists.
• Balance the sax soli with optional flute and vibe parts. Experiment with different doublings in rehearsal to find what sits best in your ensemble and allows each section to cut through the texture.
• Watch the lead trumpet's range climbing to written A-flat. Confirm your first trumpet has the security and endurance for sustained passages at this altitude, especially over the Latin feel where stamina matters as much as pitch accuracy.

Program this as a centerpiece in a mid-season jazz concert, where your ensemble has built the cohesion to handle both the groove and the solo spotlights. At just over five and a half minutes, it pairs well with a faster bebop chart and a ballad to create program balance.

• Comping and time-keeping in a Latin-based feel at a moderate tempo
• Solo performance with written melodic guidance as a scaffold
• Section blend in a sax soli with optional doublings
• Lead playing and range extension into the upper register
• Jazz ensemble ensemble cohesion across a moderate-length form
