Music

Terraria has thirteen music tracks as of version 1.1.2. 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 soundtrack can be listened to and purchased from Bandcamp.

Overworld Day
This is track number 1 in the official soundtrack. It's a cheerful, upbeat 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 or hallowed.

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 and Underworld biomes. It will also replace the regular night music on all surface biomes while there's a Blood Moon.

This track also played within The Corruption prior to the 1.0.6 patch.

Overworld Night
This is track number 3 in the official soundtrack. It's a relatively peaceful and relaxing tune. This track plays only during the night in all surface biomes; except in The Corruption, The Crimson, The Hallow, the Meteorite biome, the Jungle, and when there's a Blood Moon.

Title Screen
This is track number 4 in the official soundtrack. It's a serene tune and is probably the slowest track in the game. 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 and Cavern layers of the world, which are by far the largest biomes in the game before hardmode is reached. At this point, this track 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.

Boss 1
This is track number 6 in the official soundtrack. It's a loud, frenetic tune. It plays during invasions by the Goblin Army and during the fight with every normal mode boss: Eater of Worlds, Skeletron and the King Slime. It also plays during the battle with Skeletron Prime, in hardmode.

Jungle
This is track number 7 in the official soundtrack. It has an unique feel to it with a heavy emphasis on its background sounds. 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 resembles the Overworld Day track, but with a heavily distorted, menacing feel to it. 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.

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

The Hallow
This is track number 10 in the official soundtrack. It has a very upbeat tone and makes heavier use of physical instruments than other tracks. 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
This is track number 11 in the official soundtrack. It's a very hectic tune. It plays during the fight with the Wall of Flesh and The Twins.

Boss 3
This is track number 13 and the last in the official soundtrack as of 1.1.1. It's much slower and less intense than the other boss fights, giving it a more frightening tone. It plays during the fight with The Destroyer, as well as invasions by the Frost Legion.
