Adding commands to play .mp3

I have the below code working to spin a stepper motor. I have the arduino connected to an .mp3 card, but need to add the code to get it to play. I have added what I believe is the correct code (see below in red). Any help is appreciated. Thanks in advance

/*
Stepper Motor Control - one revolution

This program drives a unipolar or bipolar stepper motor.
The motor is attached to digital pins 8 - 11 of the Arduino.

The motor should revolve one revolution in one direction, then
one revolution in the other direction.

#include <Stepper.h>
int x = 0;
const int stepsPerRevolution = 200; // change this to fit the number of steps per revolution
// for your motor

// initialize the stepper library on pins 8 through 11:
Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11);

void setup() {
// set the speed at 60 rpm:
myStepper.setSpeed(63);
// initialize the serial port:
Serial.begin(9600);
}

void loop() {
if (x <= 10)
{ // step one revolution in one direction:
Serial.println(“clockwise”);
myStepper.step(stepsPerRevolution);
// delay(500);
x++;
}

// step one revolution in the other direction:
// Serial.println(“counterclockwise”);
// myStepper.step(-stepsPerRevolution);
// delay(500);
}

void setup(){
** Serial.begin(4800);**
}
void loop(){
** Serial.write(0x01);**

Because your post is breaking the rules about posting code.

Now post code that compiles or post the error message you get when it fails as that code you posted fails.

have added what I believe is the correct code

Here is a clue, it is not even remotely correct, and does not begin to address what you need to do.

You are trying to do something that is too hard for your present knowledge. Do some more tutorial examples before attempting this.
