Mastering the Nu-Disco Groove
"Vowels" by Capital Cities is a standout track from their debut album In a Tidal Wave of Mystery. Unlike power ballads that demand immense range, this song is a masterclass in rhythm, attitude, and phrasing. The lyrics playfully describe being "tongue-tied" and communicating through sounds rather than words.
To sing this well, you need to lock into the beat. The vocals are dry, punchy, and sit right in the pocket of the bassline. Let's breakdown how to capture that cool, indie-pop vibe without sounding flat.
AI Coach Tip: Watch Your Diction
Because the hook relies entirely on vowel sounds ("I-E-A-I-A-I-O"), lazy pronunciation will ruin the effect. Our analysis shows users score higher when they exaggerate the shape of their mouth for each vowel.
Phase 1: The Rhythmic Verses (0:15 - 0:45)
The verses are sung in a lower register, sitting comfortably in F# Minor. The delivery should be almost spoken-word but with melody. This style requires "staccato" phrasing—keeping the notes short and detached.
The Trap: It is easy to drag the tempo here. Keep your breath support engaged but light. Do not push too hard from the chest; let the microphone (or your phone) do the work.
Phase 2: The Chorus Hook (0:45 - 1:15)
Here is the earworm: "I-E-A-I-A-I-O". This sequence repeats and requires a bit more energy. The notes jump up slightly, but stay within the chest voice range (topping out around F#4).
- Articulation: Make sure the "E" sound doesn't get nasal. Smile slightly while singing to brighten the tone.
- The "O": Round your lips significantly on the final "O" to give the phrase a clean finish.
- Groove: Nod your head while recording. If your body isn't moving, your vocals will sound stiff.
Phase 3: The Bridge & Outro
The song features extended instrumental breaks with trumpets, but the vocal ad-libs in the outro require stamina. You will be repeating the hook with higher energy. Ensure you are breathing deeply from your diaphragm during the instrumental breaks so you don't run out of air during the final repetitions.
Frequently Asked Questions
The melody consistently hits an F#4 in the chorus. It is a very safe range for most male voices and a comfortable low range for female voices.
Yes. Because it does not require complex runs or extreme high notes, it is perfect for working on your timing and rhythm fundamentals.
Try varying your volume (dynamics). Sing the verses slightly softer and punch the vowels in the chorus harder. This contrast brings the performance to life.
