just Learned the second thing needed for this project, i learned how to make a buzzer and subsequently use buttons to turn it into an keyboard instrument of sorts. here is the code:  int notes[] = {262, 294, 330, 349};void setup(){  Serial.begin(9600);}void loop(){  int keyVal = analogRead(A0);  Serial.println(keyVal);  if (keyVal == 1023){    tone(8, notes[0]);  }  else if(keyVal >= 990 && keyVal <=1010){    tone(8, notes[1]);  }  else if (keyVal >=505 && keyVal <= 1010){    tone(8, notes[2]);  }  else if (keyVal >= 5 && keyVal <= 10){    tone(8, notes[3]);  }  else {    noTone(8);  }} image is still wrongly cropped, to see the whole creation open the image in its own tab
