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 ;-)
The library makes two big assumptions:
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 | |
