Listen to a chord progression as soprano, bass, and inner voices moving at the same time. Practice pointing out which note stays, which note moves, and how a single line can continue through changing chords.

Follow one voice through a simple song by using register, lyrics, timbre, and contour as listening anchors. Hum or trace the target line while the rest of the harmony keeps sounding around it.

Read and listen to a short SATB chorale as four separate strands: soprano, alto, tenor, and bass. Practice staying with an inner voice even when the outer voices are easier to hear.

Apply the previous explanations in a guided problem.

Compare two parts at a time and recognize parallel, contrary, similar, and oblique motion. Use those motion types to describe how lines cooperate instead of hearing only the chord they form.

Separate a simple piano texture into melody, bass, and inner accompaniment, even when the notes are broken into patterns. Trace how arpeggios, repeated figures, and Alberti bass can imply continuing voices.
