Redstone Tips

 * Use blocks of gold for the block of your choice under the note blocks to get a bell sound, which sounds similar to a real doorbell
 * Right-click the first note block 6 times, and the second one 2 times, to create doorbell-like pitches.
 * You can use a pressure plate instead of a button, for an automatic doorbell.
