storing the data into progmen
or
use a microcontroller with more RAM
or
use an SD-Card to store the data

or
saving RAM by defining the notes only once as an array of int.
And for the melody storing the notes as an array of byte which needs half the RAM

Try this: I shifted the melody array into PROGMEM. It compiled for Uno at 17% instead of 113%

Thanks for the answer, but another problem has arisen.
Let's start with the fact that my board is Arduino nano.
I ran your code and got a very strange result. Moreover, when loading a sketch and when pressing the reset button, the sound is different. The buzzer just beeps like an old modem.

Sound when loading script via Arduino IDE

Sound when pressing the reset button

and... i dont know what to do...

As far as I see, you connected the speaker directly to arduino pin. This may damage the board.
What is the speaker resistance?

6

8 Ω :point_right: :point_left:

7

This speaker must be used with amplifier.
To test your code, use the arduino buzzer module .

8

Do a basic check with uploading the example-sketch "tone" from the arduino-ide

if you do a basic calculation about the current
this is

5V / 8 Ohm = 0,625 A
where an arduino-IO-pin can only withstand 0,040 A
and you should not exceed 0,020A = 20 mA

Calculating the resistance for 20 mA

5V / 0.02A = 250 Ohms
So if you want to continue driving this 8-Ohm-speaker directly from an IO-pin

insert a 270 Ohm-resistor in series

IO-pin-----270 Ohm--------8-Ohm-speaker-------GND

If you want the speaker to be louder you will have to use a transistor which can drive 800 mA like a BC338

The code from post #3 has an error. The data is being stored in PROGMEM, but the code is reading from RAM, not PROGMEM. Special methods need to be used to read from PROGMEM.

void setup() {
  for (int thisNote = 0; thisNote < notes * 2; thisNote = thisNote + 2) {

    //divider = melody[thisNote + 1];
    divider = (int)pgm_read_word(&melody[thisNote + 1]);
    if (divider > 0) {

      noteDuration = (wholenote) / divider;
    } else if (divider < 0) {

      noteDuration = (wholenote) / abs(divider);
      noteDuration *= 1.5;
    }

    //tone(buzzer, melody[thisNote], noteDuration * 0.9);
    tone(buzzer, (int)pgm_read_word(&melody[thisNote]), noteDuration * 0.9);

    delay(noteDuration);

    noTone(buzzer);
  }
}

I'd switch to a ESP based board and leave all these AVR specific resource issues behind.
