Parse intervals in shorthand notation
npm install @tonaljs/pitch-note> Pitch note support
⚠️ It's probably you don't need to use this package directly. Use tonal-note instead.
``js
import { note } from "@tonaljs/pitch-note";
note("c4"); // => { name: 'C4', oct: 4, ...}
`
Given a note name, it returns an object with the following properties:
- name: the note name
- pc: the pitch class name
- letter: the note letter
- step: the letter number (0..6)
- acc: the note accidentals
- alt: the accidental number (..., -1 = 'b', 0 = '', 1 = '#', ...)
- oct: the octave (or null if not present)
- chroma: the note chroma (0..11)
- midi: the note midi or null if octave is not present
- freq: the note frequency in Hertzes, or null if the octave is note present
Example:
`js`
note("ab4");
// =>
// {
// name: "Ab4",
// pc: "Ab",
// letter: "A",
// acc: "b",
// step: 5,
// alt: -1,
// oct: 4,
// chroma: 8,
// midi: 68,
// freq: 415.3046975799451,
// }
This function always returns an object:
`js``
note("hello"); // => { empty: true, name: "" }
