A LITTLE CLARITY
Higher score. Easier melody.
MelodyMeter rates the ease of singing a song’s recognizable main lead melody in a comfortable key. A score of 10 is easiest. You don’t need to copy the original singer’s tone, optional ad-libs, or layered backing vocals.
AI gets the conversation started
AI ratings are provisional judgments from available song information and the model’s learned knowledge. Audio has not been analyzed. We don’t present exact tempo, note range, or timing measurements without supporting evidence. Unfamiliar songs may remain unrated.
How quickly you sing the words and main notes.
How far the melody stretches from low to high.
Sudden jumps between distant notes.
Holding notes steadily without losing control.
Enough chances to breathe between phrases.
Tricky entrances, accents, and off-beat phrases.
Several quick notes on a single syllable.
The effort needed to finish the vocal part.
Changes in pace, feel, and melodic pattern.
The AI overall score is the rounded weighted average of these nine factors. Scores 1–2 are very hard, 3–4 hard, 5–6 medium, 7–8 easy, and 9–10 very easy.
The audience takes the lead after 10 ratings
Once 10 different verified emails have submitted an overall rating for a song/version, the audience average becomes the main score. We show that average to one decimal place and retain the AI estimate separately.
Each individual factor also needs 10 audience ratings before its audience score qualifies. The audience overall average uses people’s overall scores, independently of the optional factor scores.

A useful starting point
Community ratings describe the experiences of the people who voted. Your voice, familiarity with the song, and chosen key can change how comfortable it feels. Choose a key that fits your voice and practice at a comfortable volume.
