This chapter delves into the historical development of keyboard layouts in organs and pianos, uncovering the evolution of the standard 12-key configuration. It explores the various methods of octave division and the pivotal role of organ makers and musicians in shaping music composition within the constraints of the instrument's design.

When you go to a concert, you might try to get there right when the doors open. Or perhaps you take your time and skip the opening act. But generally, you want to be there when the show starts. In February, everyone who went to a concert in Halberstadt, Germany, showed up 23 years late. The performance is of a piece called ORGAN2/ASLSP. ASLSP stands for “as slow as possible,” which is how the composer meant for it to be played, and this particular day would involve a chord change. The last time ORGAN2/ASLSP had a chord change was in 2022, and this new chord will play until the next change, in August, 2026. There is a change the year after that, and the following year, and so on, until the year 2640. The full performance is meant to last 639 years. Reporter Gabe Bullard travels to Germany to witness the chord change and to discover why such a concert is even happening in the first place.
