# HumMatch

> HumMatch (hummatch.me) is a vocal-matching web app for karaoke and everyday singers: you hum 3 notes, HumMatch measures your vocal range to create a "Vocal ID", and it matches you against a vocal range database of songs, scoring each song for range fit, karaoke difficulty, and voice-type suitability, solo or across a group (SquadMatch, Drive Mode).

HumMatch maintains the HumMatch Vocal Range Database: 66,000+ songs across 5,063 artists, with artist tessitura, median pitch, and vocal warmth measured directly from original recordings via pitch extraction. Statistics from the database are free to cite with attribution to HumMatch.

## Key pages

- [Song directory](https://hummatch.me/songs): Browse every song-fit page; each song page lists vocal range (low/high note, span in semitones), karaoke difficulty, likely voice fit, and safer alternatives.

- [AI vocal coach](https://hummatch.me/ai-vocal-coach): AI coaching grounded in the singer's measured Vocal ID (range, stability, session results), never a questionnaire; free micro-session, weekly session on Squad Leader, unlimited on the Coach plan.
- [Song Ladder](https://hummatch.me/song-ladder): Karaoke difficulty as a visible five-rung progression built from the singer's measured range: songs scoring 85%+ ("in your pocket") down to honest "someday" songs, with harder songs unlocking as the measured voice grows.

- [Note finder: what note am I singing?](https://hummatch.me/note-finder): Names the note you are singing in real time, with octave and intonation.
- [Vocal range song pages](https://hummatch.me/range/e3-b4): Per-range pages at /range/<low>-<high> (e.g. /range/e3-b4, /range/f-sharp-3-c5) listing real counts and the most popular catalog songs that fit entirely inside that vocal range, with voice-type interpretation.
- Spanish mirrors: [prueba de rango vocal](https://hummatch.me/es/prueba-de-rango-vocal), [detector de tono](https://hummatch.me/es/detector-de-tono), [buscador de notas](https://hummatch.me/es/que-nota-estoy-cantando).

### Catalog statistics

- Total songs: 66,000+; songs with vocal range data (lowest and highest sung note): 33,880.
- Songs with a documented range source: 33,880.
- Artists covered: 5,063; genres: 706.
- Average vocal range required by a song: 21.2 semitones (about two octaves).
- Range width distribution: 2,111 songs within one octave; 3,185 at 1-1.5 octaves; 22,642 at 1.5-2 octaves; 5,942 over two octaves.
- Widest range in the catalog: "Time to Say Goodbye" (Andrea Bocelli / Sarah Brightman), F#2-C6 (42 semitones).

### Measured artist vocal profiles (audio-extracted)

HumMatch runs pitch extraction on original recordings to measure full range, tessitura (25th-75th percentile pitch band), median pitch, vibrato, and a 0-1 spectral warmth index per artist.

- Average measured tessitura width per artist: 11.5 semitones (less than one octave).
- Average measured tessitura width per recording: 11.4 semitones.
- Average measured vocal warmth index: 0.8.

### Conventions

- Pitches are stored as MIDI note numbers and written as note names with middle C = C4.
- Tessitura = the 25th-75th percentile band of sung pitch in a recording (the comfortable zone), narrower than full range.
- Warmth index = 0-1 spectral warmth measure from timbre analysis of the isolated vocal.
