Chop-Monster, Book 2: Trombone 3 Book

Book 2 of Chop-Monster respects the fact that improvisation mastery requires time and strategic progression. By narrowing the harmonic focus to the ii-V-I progression across three keys, Berg gives trombonists a deep well to draw from rather than scattered shallow pools. The call-and-response format transforms the page into a conversation, which means students actually internalize these changes instead of just reading about them.

The ii-V-I progression is the backbone of jazz vocabulary, and working through these changes in multiple keys creates a kind of musical muscle memory that feels like liberation when you finally reach a jam session. There's an economy to Berg's approach; no excess, no filler, just the essential harmonic movement repeated in different contexts until it becomes second nature.

Trombonists in jazz ensembles who completed Book 1 and are ready to tackle functional harmony beyond static chord tones. This works equally well for high school jazz programs and serious student musicians seeking structured improvisation practice outside of ensemble rehearsal.

• Listen to the recorded jazz ideas multiple times before attempting your own response. The inflection and phrasing matter as much as the notes themselves.
• Practice the ii-V-I progression in all three keys (concert B-flat, E-flat, F) without the book so your slide positions become automatic.
• Record yourself and play it back against the accompaniment. Hearing your own phrasing alongside the rhythm section reveals rhythmic or harmonic problems immediately.
• Don't rush through the imitation phase. Berg built this method on repetition because repetition is how muscle memory forms in your slide hand and embouchure.

Assign Book 2 to your jazz band's trombone section as a summer or fall semester method text, pairing it with the recorded accompaniment to create consistent daily practice routines. You might also use it as remedial material for students who need reinforcement with basic changes before tackling the full chart book.
