Understanding the Technique-Bonus Formula and Its Cap: Stacking Vibrato, Scoops, and Melisma Wisely

"How do you do vibrato, scoops, melisma, and falls?" was already covered in a separate article. This one goes a level deeper and looks, in actual numbers, at exactly how far each of those techniques moves your score. Since technique isn’t one of the heavily weighted axes, knowing where to put your effort for the best return makes your practice priorities much clearer.

The technique axis is 12 of 100 points, split between four techniques

Utavie’s scoring is built from five axes: pitch 45 points, stability 18 points, expression 15 points, technique 12 points, and rhythm 10 points. Technique is 12 of those points, calculated by summing the detection results for vibrato, scoops, melisma, and falls into a "normalized score (0–1)" and multiplying it by 12. In other words, even maxing out the technique axis only earns you 12 points of your overall total.

The per-technique cap isn’t evenly split

A normalized score of 1.0 (= 12 points) breaks down as: vibrato up to 0.5, scoops up to 0.2, melisma up to 0.15, falls up to 0.15. Converted into points, that comes out to:

• Vibrato: up to 6.0 points (this single technique accounts for half of the normalized score)
• Scoops: up to 2.4 points (0.04 points per occurrence, capping at 5 occurrences)
• Melisma: up to 1.8 points (0.05 points per occurrence, capping at 3 occurrences)
• Falls: up to 1.8 points (0.05 points per occurrence, capping at 3 occurrences)

Even stacking scoops, melisma, and falls all the way to their caps only adds up to 6.0 points total — the exact same as the cap for vibrato alone. That means "nailing vibrato reliably" has a bigger impact on your score than "sprinkling in all four techniques evenly."

Why vibrato accounts for half: duration multiplied by quality

The vibrato score is calculated as "quality × (total wavering seconds divided by 3 seconds, capped at 1)." Quality is determined by how regular the oscillation is (whether the wave sizes stay consistent), and the seconds figure is the total duration of detected vibrato across the whole song. You don’t need one long sustained stretch — the total can come from multiple spots added together, like 2 seconds at the end of the chorus plus 1 second before the interlude.

Rule of thumb: once you hit 3 seconds, the duration side is maxed out

Once a total of 3 seconds of good-quality vibrato is detected, you can’t earn any more from duration. Adding a fourth second or beyond doesn’t move the score at all. If you want to keep gaining points past that point, the right direction isn’t adding more seconds — it’s practicing to improve the regularity (quality) of the oscillation.

Scoops, melisma, and falls cap out based on "occurrence count"

These three are designed so that a fixed number of points is added per detected occurrence, capping out after a set count. Scoops count toward your score up through the 5th occurrence, melisma and falls through the 3rd, and beyond that, no matter how many more times they’re detected, the bonus is zero. In other words, a delivery style that piles on six or seven scoops right at the top of the chorus is putting in completely wasted effort from the 6th one onward.

• Scoops: cap at 5. Using them sparingly, at points where you want to add emotion — like the opening line or the top of the chorus — is more than enough to reach the cap.
• Melisma: cap at 3. The common-sense idea of using it "as an accent a few times per song" lines up exactly with the scoring cap.
• Falls: cap at 3. Picking a few spots where you want to leave some lingering emotion — like the tail ends of phrases in a ballad — is enough.

Priority order: what’s the best return on your training time?

1. Lock down pitch and stability first (63 combined points — more than 5x technique). Technique practice can wait if this foundation is shaky.
2. Get to where you can hold a long tone steady for 5 seconds without wavering. Vibrato can’t build a stable wave without a foundation that controls the wavering in the first place.
3. Get to where you can hold vibrato for a total of 3 seconds, regularly. This is the single practice with the biggest point impact on the technique axis.
4. Add scoops at a few spots at the start of a phrase. Once you hit 5, you’re at the cap — you now know not to chase more than that.
5. Add melisma and falls once or up to three times, at spots where they’ll stand out. Pushing past that doesn’t add anything from the 4th occurrence on.

Why chasing bonus points alone can backfire

Overusing scoops, or adding ornamental wavering even when it’s not a long tone, throws off the judgment for pitch and stability. Technique can only earn you a handful of points at best, while the point loss from disrupted pitch or rhythm tends to be larger. Knowing the caps for technique makes it easier to reason: "this technique is already at its cap, so it’s not worth chasing further at the cost of my pitch."

Frequently asked questions

Q. Can I get a high score by training technique alone?

No. The technique axis caps at 12 points, which is far outweighed by the combined 88 points from pitch (45), stability (18), expression (15), and rhythm (10). Think of technique strictly as a finishing touch layered on top of the foundation.

Q. Does vibrato score higher the longer I hold it?

Once the running total across the whole song hits 3 seconds, the duration-based points cap out. Holding it longer than that adds nothing further. If you want to push past 3 seconds, stabilizing the regularity (quality) of the wavering is what actually pays off.

Q. Is it a waste to add more than 6 scoops?

Anything past the 6th doesn’t earn bonus points, but it isn’t penalized either. That said, if forcing in extra occurrences throws off the pitch or rhythm of your entry, that disruption gets penalized on those other axes. Once you know 5 occurrences hits the cap, you can decide there’s no need to force in a 6th.

Summary: knowing the point breakdown decides your practice priorities

Of the technique axis’s 12 points, vibrato alone accounts for half at 6 points, while scoops, melisma, and falls each cap out based on occurrence count. Rather than chasing sheer numbers, the most efficient approach is nailing 3 regular seconds of vibrato, and placing scoops, melisma, and falls naturally, capped at their occurrence limits.
