go-music-chord-note provides utilities for chords and notes.

Usage

package main

import (
    "github.com/bayashi/go-music-chord-note/note"
    "github.com/bayashi/go-music-chord-note/chord"
    "github.com/bayashi/go-music-chord-note/scale"
)

func main() {
    n, _ := note.NoteNumber("Db") // "Db"
    println(n) // 1

    n2, _ := note.NoteNumber("C9") // "C" on octave 9
    println(n2) // 120

    chordName, _ := chord.GetChord("Csus4")
    println(chordName[0]) // "C"
    println(chordName[1]) // "F"
    println(chordName[2]) // "G"

    chordNumber, _ := chord.GetChordAsNumberList("sus4")
    println(chordNumber[0]) // "0"
    println(chordNumber[1]) // "5"
    println(chordNumber[2]) // "7"

    scaleNumber, _ := scale.GetScale("Ionian")
    println(scaleNumber[0]) // "0"
    println(scaleNumber[1]) // "2"
    println(scaleNumber[2]) // "4"
    println(scaleNumber[3]) // "5"
    println(scaleNumber[4]) // "7"
    println(scaleNumber[5]) // "9"
    println(scaleNumber[6]) // "11"
}

See tests for more functions.
