Music

Terraria has over thirty music tracks total as of version 1.3. Each one will play and loop endlessly while the player is in a specific biome or while certain events are taking place. Music is individual to each player, and as such its volume can be lowered or disabled entirely within the Options menu.

All the music in Terraria was composed by Scott Lloyd Shelly of Resonance Array.

In-game, it is possible to record and play these songs using the Music Box accessory.

PC soundtrack
The soundtracks can be listened to and purchased from Bandcamp. Currently, several themes are unavailable for purchase. They may be released in the future.

Overworld Day
This is track number 1 in the official soundtrack. It's a cheerful, upbeat, and simple tune that's almost surely to be the first one heard by a new player. It plays during the day in the Forest only if it is not corrupted/crimson or hallowed. It also plays on the title screen on the mobile version.

Eerie
This is track number 2 in the official soundtrack. It's slower and more sinister than most other tracks. It always plays in the Meteorite mini-biome. It will also replace the regular night music on many surface biomes while there's a Blood Moon.

This track also played within The Corruption prior to the 1.0.6 patch, the Dungeon prior to the 1.2 patch, and the Underworld prior to the 1.3.0.1 patch.

Overworld Night
This is track number 3 in the official soundtrack. It's relatively peaceful and relaxing, but its tune is a minor one. This track plays only during the night in the Forest, Ocean, Hallow and Snow surface biomes, but is replaced by Eerie when there's a Blood Moon.

Title Screen
This is track number 4 in the official soundtrack. It's a serene, solemn tune and is probably the slowest track in the game. Short and hooking, it normally only plays in the main menu of the game, before entering a world; however, it can play in-game when its corresponding music box is crafted and used.

Underground
This is track number 5 in the official soundtrack. It's fast and has an almost robotic tone. It plays within the Underground layer of the world unless the alternate/cavern soundtrack is already playing, and will continue into the Cavern layer until the end of the track, after which it transitions to the alternate soundtrack. These two are by far the largest biomes in the game before hardmode is reached. At that point, this track, along with the alternate soundtrack, may become significantly more difficult to access, as the Underground Hallow and the Underground Corruption (both of which have different tracks) will quickly start spreading through the underground.

Cavern/alternate underground
This track plays in the Cavern layer, but does not start until the Underground soundtrack finishes. Similarly, this track continues playing in the Underground until the end of the track. This track, along with the Underground track, become harder to access in hardmode due to the spread of Underground Corruption and Underground Hallow.

Boss 1
This is track number 6 in the official soundtrack. It's a loud, frenetic tune, similar to battle music. It plays during the fight with the Eye of Cthulhu (PC exclusively), King Slime, Eater of Worlds, Skeletron, Lepus, and Turkor the Ungrateful. In hardmode, it also plays during the fight with Skeletron Prime and Duke Fishron.

It also played during the Goblin Army Event prior to the 1.3.0.1 update.

Jungle
This is track number 7 in the official soundtrack. With an exotic, relaxed tune, it has an unique feel to it with a heavy emphasis on percussion. It plays only in the Jungle (day and night) and its underground extension, the Underground Jungle.

This track was added in the 1.0.5 patch. Before it, the Jungle used the Overworld Day/Night tracks and the Underground Jungle used the regular Underground track.

Corruption
This is track number 8 in the official soundtrack. Its melody somewhat resembles the Overworld Day track, but altered and slowed to sound much darker and more menacing. It plays in The Corruption during both day and night, but only on the surface. Once a world has entered hardmode, the Corruption will spread aggressively and this track will also play in Deserts, Oceans and Floating Islands that have been corrupted.

This track was added in the 1.0.6 patch. Before it, the Eerie track was used.

Underground Corruption
This is track number 9 in the official soundtrack. This track is a combination of The Corruption and Underground tracks. It plays within the Underground Corruption, likely only accessible once a world has entered hardmode.

The Hallow
This is track number 10 in the official soundtrack. It has a heavenly, happy tone and makes use of instruments related to this idea, especially the harp. It plays in The Hallow, but only on the surface and during the day. Once a world has entered hardmode, the Hallow will spread aggressively and this track will also play in Deserts, Oceans and even Floating Islands that have been hallowed.

This track was added in the 1.1 patch, along with the biome it plays in.

Boss 2

Ocean
This is track number 1 in Volume 2 of the official soundtrack. It is a tranquil theme with a somewhat slower pace than other daytime themes. It plays in the Ocean biome, but only if it hasn't been taken by the Hallow, the Corruption or the Crimson; their respective surface themes will play then.
