A Note Block being triggered and playing a note.
Crafting
Note Blocks can be crafted by placing 8 planks in a square with redstone at the center.
Music
Note blocks play a note when hit or when powered by redstone. Redstone current only causes the note to play once, even if it is a continuous current. A note block must have a block of air above it to play a sound.
Each time a note block plays a note, a note particle will fly out of the top, with the color depending on the pitch (but not the instrument). http://www.youtube.com/watch?v=Exriq7QEckA
Right clicking increases the note pitch up a half step, with a total of two full octaves being available to play. After reaching high C, right clicking again resets it to low C, as does breaking the block and picking it back up.
The instrument played depends on the block underneath the note block:
| Block type | Instrument |
|---|---|
| Glass/Glowstone | Sticks |
| Stone/Cobblestone/Obsidian/Netherrack/Bricks | Ordinary drum |
| Wood Blocks | Marimba |
| Sand/Gravel/Soulsand | Snare drum |
| All other blocks. | Piano |
Other Information
Note Blocks can only play when there is at least a block of air above them.
