- Sherlock's Theme. It's remarkable for how it's utilized in the show; it usually comes in whenever something hilarious or awesome or hilariously awesome happens, and this has the effect of inducing a Pavlovian response in the viewer. After a few episodes, you need only hear those opening notes before a smile starts spreading across your face.
- Moriarty's theme is epically menacing.
- The hauntingly beautiful song that is Irene Adler's theme.
- Which Bottle? is tension given musical form.
- The main theme is pretty good too. The Reichenbach Ballad is a minor-key variation. The feels, the FEELS.
- John's theme, the tear-jerkingly sad and beautiful War. Made ten times worse with One More Miracle.
- The whirlwind of emotions felt/portrayed by Sherlock at the end of Series 2 is best shown musically with Prepared to Do Anything. The song halfway through culminates the starting half's tension with a violin and piano section that mirror John's and Sherlock's themes in a minor key that just begs the tear ducts.
- The brilliant use of Nina Simone's "Sinnerman" for the court scene.
- Series 3 produced plenty of memorable tracks:
- How It Was Done, the rock opening signifying the return of the coolness that is Sherlock Holmes.
- John is Quite a Guy is absolutely gripping, especially as it crescendos to its startlingly gripping finish.
- Stag Night. Dubstep FTW!
- Waltz for John and Mary.
- The Lie in Leinster Gardens and Addicted to a Certain Lifestyle. Both double as Tearjerkers.
- The East Wind.
- And last but not least, Redbeard, the song that plays as Sherlock wills himself back to life.
