What can two hands and 25 bars do? In Bach's Invention No. 13 in A minor (BWV 784), a tiny musical idea sparks a restless conversation.

Join Andrew Cook and Lisa Partington at the piano as they pull the voices apart, try musical what-ifs and reveal how J. S. Bach builds tension, surprise and a sense of home. Along the way: a family music notebook, a chord that won't settle, and an ending worth hearing twice.

No music-reading or theory background needed. Hear the ideas demonstrated, then listen afresh to Luis Kolodin's complete performance at 46:47.

Listen for

• Counterpoint: two melodies with minds of their own.
• Rhythm and harmony: what keeps the music moving.
• Performance choices: how touch, timing and balance change what you hear.
