Chop-Monster, Book 1: Trombone 3 Book

Chop-Monster uses call-and-response pedagogy, which mirrors how jazz was historically transmitted. Trombone players internalize jazz vocabulary through listening and imitation rather than abstract rule-learning, making the style tangible and ear-driven. Berg's sequence in Book 1 (Ima7, iimi7, V7 changes plus blues) builds a concrete foundation that prepares students for the ii-V-I progressions in Book 2.

Playful and grounded. The call-and-response format creates conversation rather than lecture, and the specific harmonic vocabulary of Book 1 (major seventh and minor seventh sounds, the blues) is immediately recognizable and fun to explore. You're learning a language by speaking it, not by studying grammar.

Jazz ensemble students new to improvisation who benefit from structured listening and imitation. Trombone players (specifically those reading the third part) in middle school through college jazz ensembles or combos.

• Record yourself improvising over the provided changes, then listen back to hear how your phrasing and rhythm sit against the harmonic movement; this trains your ear faster than reading alone.
• Isolate one chord at a time before connecting them in sequence; spend several practice sessions on just the Ima7 sound until the characteristic tones feel natural under your slide.
• Listen to recorded jazz soloists (especially trombonists) playing these same harmonic changes to absorb authentic articulation, rhythm, and phrasing choices.
• Work through the call-and-response exercises at a slower tempo first, focusing on matching inflection and articulation exactly before moving to performance speed.

Use this as the core improvisation curriculum for your jazz ensemble's third trombone part, pairing it with live rhythm section accompaniment or the recorded backgrounds. Progress through Book 1 during the fall semester, then move to Book 2 once students show confidence with the ii-V-I progression, ensuring continuity across your jazz program.
