Insufficient clear notation explanation hinders adoption

Updated 10/20/2026, 22:04:17

Problem

The post introduces a base‑12 numeric music notation for an isomorphic keyboard, but commenters point out that the system lacks a clear explanatory guide, mixes up numeric conventions, and obscures musical relationships, making it hard for musicians to adopt or use on paper.

It took me a while to understand what the numbers were actually trying to indicate (in part because I'm used to numbers in sheet music being suggestions of which finger should play the given note).

People who know Nashville system are gonna struggle with that... musicians think in relationships, not absolute notes, and this kind of obscures those relationships.

I really enjoy all the alternative music notation projects that popup on HN. Based on the comments, I think this one could use a page explaining the notation and instrument before diving into sheet music. Also looks pretty difficult to use with pen and paper but I'm probably in the minority there
fact
I've been playing around with a new kind of isomorphic music keyboard that uses a base-12 notation, and wanted some sheet music to learn some new music for it.
