Leipzig

Here is the concerto in D-minor.
He needs to unlock the very world.
Harmonics explode in each spin.
The sparks always find him.
Each staff is an uncovering.
Tracking first principles.
Here is the science of the notes.
The keys discover the pattern
every single time. Harpsichord,
clavichord, it makes no difference.
He is the scribe. The onlooker
with the busy fingers. A bystander.
The singing starts at night
when no one sees.
