By the end of this lesson, students will be able to:
Identify and define the characteristics and types of chromatic sequences, including descending and ascending patterns.
Explain the harmonic and melodic functions of chromatic sequences and their role in modulation and voice leading.
Analyze musical excerpts to identify chromatic sequences and discuss their structural and expressive effects.
Compose short harmonic progressions and melodies that incorporate chromatic sequences, demonstrating an understanding of their function and voice leading.

Characteristics: What are the key characteristics of chromatic sequences, and how do they differ from diatonic sequences?
Sequence Types: What are some of the different types of chromatic sequences introduced in the reading? Starting on the tonic, compose a brief example of each as a group, alongside the diatonic variant (where applicable). Listen to each example and describe how the diatonic and chromatic versions vary in expressive effect.
Sequence ID: Identify sequences in short excerpts by Ana Bon, Clara Schumann, and José Garcia (from Diverse Music Theory Examples)
Composition: Compose a chord progression that includes a chromatic sequence, then part-write the progression in 4-part keyboard or chorale style. Swap with a partner to check voice leading. If there's time, add texture and a melody to your chord progression.

Recomposition: Pick examples from the Music Theory Anthology that use diatonic sequences. Rewrite each excerpt with a chromatic sequence. Find examples of diatonic sequences in the anthology here.
Chromatic Sequences: Select examples from the section “Chromatic Sequences” for analysis. Identify the chords using Roman numerals or chord symbols. Identify each sequence by type.
