Scale Generator

You see, I never knew how to "create" scales in my mind, my music theory is really bad, so I coded this to help me with generating scales to practice with.

Example

const CHROMATIC_SCALE = ["C", "C#", "D", "D#", "E", "F", "F#", "G", "G#", "A", "A#", "B"];

const SCALE_FORMULAS = {
  major: [0, 2, 4, 5, 7, 9, 11],
  naturalMinor: [0, 2, 3, 5, 7, 8, 10],
  harmonicMinor: [0, 2, 3, 5, 7, 8, 11],
};
