Hi team, 
I have a buzzer attached to my arduino uno.
i want to know is there any tool for making songs,melodies etc. like super mario etc.
i have the following code that plays a single melody for now. I dont know how to make another.
'/*
* Play a simple tune using a piezzo
* Based on example created by Tom Igoe
* http://arduino.cc/en/Tutorial/Tone
*/
// Make sure the file pitches.h is placed in the same folder as this sketch
#include "pitches.h"
// Piezzo element connected to Arduino pin 12 and ground
const int buzzerPin = 13;
// Array with the notes in the melody (see pitches.h for reference)
int melody[] = {NOTE_A4, NOTE_A4, NOTE_A4, NOTE_F4, NOTE_C5, NOTE_A4, NOTE_F4, NOTE_C5, NOTE_A4, NOTE_E5, NOTE_E5, NOTE_E5, NOTE_F5, NOTE_C5, NOTE_A4, NOTE_F4, NOTE_C5, NOTE_A4};
// Array with the note durations: a quarter note has a duration of 4, half note 2 etc.
int durations[] = {4, 4, 4, 5, 16, 4, 5, 16, 2, 4, 4, 4, 5, 16, 4, 5, 16, 2};
int tempo = 120; // tempo for the melody expressed in beats per minute (BPM)
void setup() {
 playTune(melody, durations, tempo);
}
void loop() {
 // no need to repeat the melody.
}
void playTune(int notes[], int durations[], int BPM)
{
 int tuneSize = sizeof(melody) / sizeof(int);
Â
 // iterate over the notes of the tune:
 for (int thisNote = 0; thisNote < tuneSize; thisNote++) {
  // For details on calculating the note duration using the tempo and the note type,
  // see http://bradthemad.org/guitar/tempo_explanation.php.
  // A quarter note at 60 BPM lasts exactly one second and at 120 BPM - half a second.
 Â
  int noteDuration = (int)((1000 * (60 * 4 / BPM)) / durations[thisNote] + 0.);
  tone(buzzerPin, notes[thisNote],noteDuration);
  // to distinguish the notes, set a minimum time between them.
  // the note's duration + 20% seems to work well:
  int pauseBetweenNotes = noteDuration * 1.20;
  delay(pauseBetweenNotes);
  // stop the tone playing:
  noTone(buzzerPin);
 }
}
