+====== Tetrismelodie ======
+Die Tetrismelodie besteht aus drei Tonspuren: Sopran, Alt und Bass. Diese sind im Programm als einzelne Melodien gespeichert. Mit mehreren Arduinos kannst du alle drei gleichzeitig abspielen.
+==== Sopran ====
+Der Sopran ist die Hauptmelodie, die jeder kennt. Wenn du nur eine Tonspur benutzt, dann ist diese hier zu empfehlen.

+===== Programm =====
+Das Basisprogramm hat -- wie immer -- eine Setup- und eine Loop-Funktion
+<code>
+void setup()
+{
+  // put your setup code here, to run once:
+  pinMode( 8, OUTPUT );
+}
+// loop spielt hier die Hauptmelodie (Sopran) in einer Endlosschleife.
+void loop()
+{
+  playMelody( melodyTrack1, durationsTrack1, 59 );
+}
+</code>
+Die ''playMelody'' Funktion bekommt die Melodie, die Notenlängen und die Anzahl der Töne in der Melodie.
+<code>
+void playMelody( int* melody, int* noteDurations, int length )
+{
+  // iterate over the notes of the melody:
+  for( int thisNote = 0; thisNote < length; thisNote++ )
+  {
+    // to calculate the note duration, take one second
+    // divided by the note type.
+    //e.g. quarter note = 1000 / 4, eighth note = 1000/8, etc.
+    int noteDuration = 1000 / noteDurations[thisNote];
+    tone( 8, melody[thisNote], noteDuration );
+    // to distinguish the notes, set a minimum time between them.
+    // the note's duration + 30% seems to work well:
+    int pauseBetweenNotes = noteDuration * 1.30;
+    delay( pauseBetweenNotes );
+    // stop the tone playing:
+    noTone(8);
+  }
+}
