Simply mention the hit video game Tetris to someone who has played it, and they will instantly think about the catchy music that accompanies the game. In this game, the player organizes blocks into (hopefully) organized stacks. The music of Johann Sebastian Bach is similar, in that he often takes a small musical idea (motif) and turns it into a building block out of which he builds an entire piece – much like building a house entirely out of tiny Legos.

Anyone who has played Tetris knows the main theme music (Music A), but for those more adventurous types who chose the B or C music, you might recognize the Minuet (jump to 11:35) from Bach’s French Suite in b minor. Many of the movements of this suite are built on small motivic ideas, which, when stacked correctly on top of each other, can create magnificent structures.
