ScoreJS (next)

This is an explanation of how it works the 4th iteration of the scorejs prototype. All the examples shown are valid code (at least for today ;-)

Basics

The library makes two big assumptions:

• an score is made by combining indivisible entities called elements: an object with a duration property. Currently the only type of elements supported are notes (an element with pitch property)

// # Tonal

// __tonal__ is a functional music theory library. It deals with abstract music
// concepts like picthes and intervals, not actual music.

// `tonal` is also the result of my journey of learning how to implement a music
// theory library in javascript in a functional way.

// You are currently reading the source code of the library. It's written in
// [literate programming](https://en.wikipedia.org/wiki/Literate_programming) as
