Midterms -- the time of the semester where everyone is stressed, about to lose their minds, and have exam after paper after exam. It can be hard to stay focused when there is so much going on, and stress levels are high. However, a way to push through that and calm down is to listen to classical music. Here is a list of 12 classical songs to help you relax and focus while studying:

1. "Debut" -- Melanie Laurent

This is one of my favorite (if not favorite) piano pieces. French artist Melanie Laurent, makes you feel some type of way that can help you calm down.

2. "Piano sonata No.12 in F, K.332:2. Adagio" -- Wolfgang Amadeus Mozart

3. "Beethoven's 5 Secrets" -- The Piano Guys

You may recognize the first half of this song as the music to One Republic's "Secrets." If you get distracted by singing, then this version will help you focus.

4. "He's a Pirate" -- Klaus Badelt

If you're looking for an instrumental song to pump you up when you're in a study slump, then this is the one. And even better, here is a 14-minute extended version.

5. "Piano sonata No.14 in C-Sharp minor, Op.27, No.2, 'Moonlight': I. 'Adagio sostenuto'
-- Ludwig van Beethoven, Jeno Jando

And in case you can't get enough of Beethoven, here's the full version of "Moonlight Sonata."

6. "The Cello Song" -- The Piano Guys

An upbeat twist to Bach's "Unaccompanied Cello Suite No.1: Prelude" that will brighten your mood after hours of studying.

7. "Claire de Lune" -- Claude Debussy

This is probably one of the most well-known classical songs that will help you relax right before you take an exam.

8. "River Flows in You" -- Yiruma

This is probably my second favorite piano piece following Melanie Laurent's "Debut." It's hard to put into words how peaceful and beautiful this song is.

9. "The Mission: Gabriel's Oboe" -- Ennio Morricone, Yo-Yo Ma, Roma Sinfonietta

10. "Lord of the Rings" -- Howard Shore, Philipps Jane Boyens, The Piano Guys

Not necessarily a classic but an epic instrumental that encompasses music from all of the
"Lord of the Rings" films.

11. "Andante spianato et Grande Polonaise brillante in E flat, Op.22: Andante Spianato. Tranquillo." -- Frederic Chopin

12. "Come Sail Away" -- Styx -- Covered by: Donald Gould

Okay, so this may not be a classical song, but it's a rock classic. This video of a homeless man, Donald Gould, went viral after a woman captured a beautiful moment of him performing on the main streets of Sarasota, Fla.
