A Masterclass in Vocal Texture
"Diamonds" marked a shift in Rihanna's vocal delivery. Written largely by Sia, the track features that distinct "indie-pop" pronunciation and emotional rawness. Unlike many pop anthems that rely on high-pitched acrobatics, this song is about sustained power, resonance, and timbre.
To sing this well, you need to master the balance between a warm lower register and a powerful, forward-placed belt in the chorus. It is less about range and more about endurance and tone.
AI Coach Tip: Breath Support
The line "Shine bright like a diamond" is repeated relentlessly. Our analysis shows singers often run out of air by the third repetition. Take a deep, diaphragmatic breath before the chorus hits to maintain power.
Phase 1: The Verses (Low Control)
The song starts in the A3-B3 range. "Find light in the beautiful sea..." requires a warm, chest-dominant tone.
The Trap: Many singers go too breathy here to sound "emotional," but this causes pitch instability. Keep the vocal cords connected. Think of speaking the lyrics on a pitch rather than whispering them.
Phase 2: The Chorus (The Belt)
The energy explodes here. You are belting around C#5 and D5. This is the "Shine bright" hook. The placement must be forward (in the "mask" of the face) to get that ringing quality without straining your throat.
- Vowel Modification: Don't sing a wide "Bright." Modify it slightly towards "Braht" or "Broht" to allow the jaw to drop and the sound to resonate more fully.
- Texture: Don't be afraid of a little vocal fry at the onset of words to mimic the style, but ensure you quickly transition into a clean tone.
Phase 3: The Ad-libs (F#5)
Towards the end, Rihanna throws in higher ad-libs reaching up to F#5. These are generally sung in a heady mix or falsetto. They provide a sparkly texture on top of the heavy chest belt of the main melody.
Contrast is key here. The main vocal is grounded and heavy; the ad-libs should feel light and ethereal.
Frequently Asked Questions
The highest belted note in the main melody is generally considered a D5, while the background vocals and ad-libs reach up to an F#5.
It is approachable for beginners because the melody is repetitive, but mastering the tone and stamina makes it an intermediate challenge to sing well.
Focus on vowel breaking (diphthongs) and a slightly nasal, forward placement. The Singing Coach AI app can visualize your timbre to see if you are matching her resonance.
