A Tense Moment is a song that is featured in Super Mario Galaxy. It usually plays in a pre-boss area. It has the key of E minor.
- Good Egg Galaxy (King Kaliente's Battle Fleet, Octo Lava Planet before boss fight)
- Bowser Jr.'s Robot Reactor (entire level before boss fight)
- Space Junk Galaxy (Phantom Boss Spider Zone area before boss fight)
- Battlerock Galaxy (Topmaniac's Saucer before boss fight (Topmaniac and the Topman Tribe only))
- Bowser Jr.'s Lava Reactor (entire level before boss fight)
- Dreadnought Galaxy (Topmaniac's Saucer before boss fight (Revenge of the Topman Tribe only))
In Super Mario Galaxy 2, a more unsettling remix plays, with the same chord progression for the first 18 seconds, but the last 6 seconds have a D minor chord instead of an F#7. It plays during Daredevil Comet missions that lead to a boss fight for the entire level prior to that fight and when Mario approaches Bowser's Galaxy Generator.
