Town tune

The town tune (formatted as Town Tune in and known as the island tune in ) is a melody that plays in the player's town. It is customizable and can contain one to sixteen notes.

Creation and usage
A town tune is represented by frog icons for each eighth note. They can be set to the natural pitches between G3 and E5 (almost two octaves), a question mark representing a random sharp note, a dash which sustains the previous note, and a sleeping frog representing a rest.

Town tunes are played in the following situations:
 * When the player talks to a villager or special character for the first time in a certain amount of time, the town tune plays. Each character plays a unique variation of the town tune with instruments and timing that reflect their personality.
 * At the beginning of each hour, the town hall's bells chime to the melody of the town tune.
 * When someone enters or exits a building with a door, bells will jingle to the melody of the town tune, sped up.
 * In games prior to, when the player interacts with an instrument, the tune will be played at the same speed as any music playing in the room.
 * When a villager is happy, they will sing the town tune.
