Jukebox comparator signal for every Minecraft disc (all 22)

A comparator reading a jukebox gives a signal from 1 to 15, and the number depends on which disc is inside. Disc 13 gives 1, disc 5 gives 15, and the signal stays on as long as the disc sits in the jukebox. In Java 1.19.4 and later, a playing jukebox also powers adjacent redstone with a full 15 until the song ends.

These values are for Java Edition, which has 22 music discs as of 26.3. If you play Bedrock, check the wiki for its values. New to jukeboxes? Start with how to make a jukebox in Minecraft.

Which discs share a signal

The 12 original C418 discs run in order from 1 (13) to 12 (wait). Pigstep, otherside and 5 then took 13, 14 and 15. Every disc added from 1.20 onward reuses an existing value, which creates pairs:

• Signal 8: stal and Bounce
• Signal 9: strad and Lava Chicken
• Signal 10: ward and Tears
• Signal 11: 11 and Creator (Music Box)
• Signal 12: wait and Creator
• Signal 13: Pigstep and Precipice
• Signal 14: otherside and Relic

Signals 1 to 7 each belong to one disc. So does 15, which only disc 5 gives.

A comparator can't tell the two discs in a pair apart. If your build reacts to Pigstep, it reacts to Precipice too. Either keep only one disc from each pair in your system, or accept that both will trigger it.

The two jukebox signals: comparator vs playing

A jukebox sends out two different redstone signals. Mixing them up is a common reason a jukebox build doesn't do what you expect.

1. The comparator signal (1 to 15). A comparator reading the jukebox outputs the disc's value from the table above. It stays on while the disc is inside, even after the song finishes.

2. The playing signal (always 15). In Java 1.19.4 and later, a jukebox powers adjacent redstone with signal 15 while a disc plays, no matter which disc. When the song ends, this signal stops, even if the disc is still inside.

	Comparator signal	Playing signal
Strength	1 to 15, depends on the disc	Always 15
On while	Disc is inside	Song is playing
Read by	A comparator reading the jukebox	Adjacent redstone
Tells you	Which disc (or pair) is inside	Whether music is playing now

A disc plays once and doesn't loop by itself. That makes the playing signal useful: it tells your build when the song is over.

How hoppers work with a jukebox

In Java 1.19.4 and later, hoppers and droppers can put discs into a jukebox and take them out again.

The playing signal is what makes this useful. While a disc plays, the jukebox's own signal locks the hoppers next to it. When the song ends, that signal stops, and a hopper pulls the disc out.

You don't need any extra redstone for this timing. The jukebox handles it itself.

Build idea 1: a disc detector

A disc detector uses the comparator signal to react to what's in the jukebox.

1. Craft a jukebox: 8 planks of any wood around 1 diamond.
2. Connect a comparator so it reads the jukebox.
3. Run its output to whatever you want to trigger.
4. Insert a disc and check the signal against the table.

Because the strength changes with each disc, you can set your build to respond to a specific value instead of just on or off. Keep the pairs in mind. A detector set for signal 15 is the only one that can't be fooled, since disc 5 has no twin.

If you want to know whether music is actually playing, use the playing signal from adjacent redstone instead. It turns off when the song ends, while the comparator signal stays on.

Build idea 2: an automatic disc changer

A disc doesn't loop, so a jukebox goes quiet after one song. An automatic disc changer fixes that using only hoppers and the jukebox's built-in lock.

The idea has three parts:

1. A hopper inserts a disc, and the jukebox starts playing.
2. While the song plays, the jukebox locks the hoppers next to it.
3. When the song ends, a hopper pulls the finished disc out, making room for the next one.

Fill your hoppers or a connected chest with discs and you get a playlist that runs without you touching it. For ideas on what to build around one, see our Minecraft nightclub build ideas.

On JukeZone, the nightclub at spawn sits inside a giant jukebox, and DJ JUKE takes song requests, so you can hear music without wiring up a changer yourself.

Other things a playing jukebox does

While a disc plays:

• Allays dance if they're within 3 blocks of the jukebox. Give a dancing allay an amethyst shard to duplicate it. There's a 5-minute cooldown before it can duplicate again.
• Parrots dance near the jukebox.

A disc changer next to an allay setup keeps the music going, so you don't have to swap discs by hand between duplications.

Common mistakes

• Your output stays on after the song ends. You're reading the comparator signal, which lasts as long as the disc is inside. Use the playing signal if you only want "music on."
• A detector triggers for the wrong disc. That disc probably shares a value with the one you wanted. Check the pairs list above.
• Your Bedrock build doesn't match these numbers. The table is for Java. Check the wiki for Bedrock.
