Pitch trainer · by ear
Hear a note, sing it
The page plays a note and does not say which. Sing it and hold it. When you have stayed on it for one second the page names the note.

How pitch matching works
Press Play a new note. The page picks a note at random between the lowest and highest notes you chose and sounds it for a second and a half. Start the microphone and sing what you heard. The readout shows the note you are on, as it does on every page, but not the note you are looking for.
A match is your pitch staying within the tolerance of the note for one full second, judged on the centre of the last third of a second, so a vibrato around the note is not held against you. A gap in the sound longer than a quarter of a second starts the second again. While the note is sounding the microphone is ignored.
Hear it again repeats the note. Show the note names it and ends the attempt: a note you asked to see is counted as played, not as matched.
Any octave, and which notes
With Any octave counts ticked, singing the note an octave or two away from where it was played is a match. Untick it to be held to the exact octave. If you have measured your range on the vocal range test, Use my measured range sets the lowest and highest notes to it. That range is read from this browser’s own storage.
What this page does not do
It plays notes from C2 to D6 and hears the same span. The tally counts notes played and notes matched since the page was loaded; it is not stored and not sent, and it is not a score of anything but this visit. This is a measurement of pitch, not vocal coaching or an assessment of hearing.
To practise a named distance between two notes, use sing intervals. To watch your pitch as you sing, use the vocal pitch monitor.
How it measures, and what it keeps
The pitch comes from a detector that runs inside this page: the normalised square difference method of McLeod and Wyvill, tuned for a voice from C2 to D6. It was measured on 7,344 synthesised tones, not on recorded singers and not on your microphone; the method page has the tables and says what they do not cover.
The sound from your microphone goes to that detector and nowhere else: it is not recorded, stored or sent. This browser keeps three settings for the trainer’s pages, under labs.sing.a4, labs.sing.solfege and labs.sing.range. The musical facts (note names, cents, scales, intervals, voice types) are read from thirteen published articles, each listed on the method page with its revision and the date it was read.
