It is possible to make a song with a certain section that keeps repeating until a signal comes through and moves to the next thing.You can use buttons to start/stop instead of levers.You can use pistons to start/stop the song.If you have a lot of redstone, it might be helpful to color code or label what part does what in case it breaks.Be careful with water as it destroys redstone on contact.Always remember that you need a block of space above a note block.Remember that redstone dust activates all of the blocks around it, not just one.Right-click to change the pitch of the note block.Use a redstone signal to play the sound.
