This is a short tune I recorded using the Hookpad song editor at
hooktheory.com. It felt surprisingly natural to make the tune, considering that I knew nothing about making music before reading the
Hooktheory book.
It was first composed in Hookpad with its synthesized piano voices, and then it was imported into Apple's GarageBand software where other instruments were substituted, adding drama.
The playable music theory tab for the tune, with the original piano voices, is through this link:
