Just like minecraft why not add noise and a note element to the game. You can change the note particles tone and when it's powered it creates that noise. For exaple |~| = a double note |~|~| = a triple note and so on. o| = a quarter note Q| = a full note *| = an upside down full note & = a rest note ^| = an upside down quarter note and $ = one of those curly shaped rest notes. Here is the song... & |~|~|~| |~| Q| |~| Q| $ *| *| *| *| *| *| *| *|
