A Masterclass in Vocal Stamina
"Grenade" is the defining power ballad of the 2010s. Released on Bruno Mars' debut album Doo-Wops & Hooligans, it combines a driving pop beat with agonizingly desperate lyrics. The song is notorious among vocalists for its high tessitura—it stays high, and keeps going higher.
To sing this well, you need more than just range; you need "grit" without damage. The emotional delivery requires you to sound like you are in pain, but your vocal cords must remain relaxed and retracted. Here is how to break it down.
Phase 1: The Verses (Storytelling)
The song starts in D Minor with a rhythmic, almost staccato delivery on "Easy come, easy go." This sits comfortably in the middle range (A3-D4). Focus on clear diction here.
The Trap: Don't get too loud too early. The verses need to be intimate to contrast with the explosive chorus. Keep your volume at a 4/10.
Phase 2: The Pre-Chorus (The Climb)
The tension builds on "Black, black, black and blue." This is where you must shift from chest voice into a strong mixed voice. You are ascending towards the break.
- Beat me 'til I'm numb: Keep the jaw loose.
- Tell the devil: This line requires forward placement. Imagine aiming the sound at your front teeth to get that piercing quality Bruno is known for.
Phase 3: The Chorus (The High Belt)
This is the vocal Olympics. The line "I'd catch a grenade for ya" jumps to a powerful B♭4 and peaks at D5. This is very high for a male chest belt.
To hit this, engage your core muscles (support) and think of the sound going "up and over" rather than pushing it out. You need a bright, twangy tone to cut through the mix. If you feel a tickle in your throat, you are squeezing too hard—switch to a headier mix immediately.
