You can pause the music with the following instruction:

	BGSoundScript.Instance.Audio.Pause ();

In order to resume the music, use:

	BGSoundScript.Instance.Audio.Play ();

These commands may be part of any C# script, like this one:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MusicControl: MonoBehaviour {

    public bool musicOn = true; // this variable appears in the Inspector and controls the music

    void Start(){
        if (musicOn){
		BGSoundScript.Instance.Audio.Play ();
        } else {
		BGSoundScript.Instance.Audio.Pause ();
        }
    }
}

Attach this script to the camera in every scene and set the field Music On to true or false in order to enable/disable the music in each scene.
