This test takes about 3 minutes. The app plays a note, you sing it back, and you say how it felt. Step by step it finds your lowest and highest notes and, more usefully, your comfortable range: the notes a song should stay inside.
- Use headphones if you can, so the mic hears you and not the reference tone.
- A quiet room helps. Sing on an open "ahh" at a normal speaking volume.
- Don't push. If a note hurts, scratches, or cracks, mark it and stop.
- Your audio never leaves this device. Nothing is recorded or uploaded.
Lowest note held: - | Highest note held: -
Practice: match the note
Hold a key (click, touch, or type the letter shown) to hear a note. It plays for as long as you hold it. Then sing it back on an "ahh" and hold it steady. The needle shows how far flat or sharp you are in cents: 100 cents is one semitone (one piano key, about 5.9% in frequency), and under 10 cents (0.6%) is dead on.
Testing a phone, laptop, or mic: open this page on two devices, hold notes on one, and watch the other. A steady tone should read the right Hz with clarity near 1.00. Small speakers can't play the lowest notes, but their harmonics still carry the pitch.
Practice a song
Pick a song and press Sing it. After a few clicks to count you in, the notes scroll toward the blue line. Each bar is a note: higher bars are higher notes, longer bars are held longer. Sing each note as it crosses the line, and your voice draws over it.
Library: songbooks, your songs, and choir sets
Nothing here yet. Open a library or set file below, or collect songbooks from churchofjesuschrist.org. Songs you send with the Send to Sing bookmark are kept here too.
Choir set
Email or text the file, or put it on Dropbox or a website and share the link. Members open it below.
Open or save
The setup link opens this library and sets your range and part on a new phone or browser in one tap. It holds the library's private address: keep it to your own devices.
Collect songbooks from churchofjesuschrist.org
For your own home use: the Sing bookmark (see "Hymns from churchofjesuschrist.org" below to add it) reads whole songbooks (Hymns for Home and Church, Hymns, Children's Songbook) into your library, with every part, verse, topic, and voicing. Verses printed below the music are fitted to the notes by AI when this app's local helper is running.
Use it: open any page on churchofjesuschrist.org other than a song, and tap the bookmark. Pick the songbooks. To get only new or changed songs, pick your saved library file; it can also refresh the topics and voicing of the songs you have, which takes a few seconds per book. Reading songs takes a couple of seconds each (all three books about 30 minutes), then it opens this app, or saves a file to open here if it's large.
Each song keeps the data it was collected with, so newer versions of this app rebuild your songs without collecting them again.
The notes you can sing easily; songs are moved to fit inside them. Not sure? The range test above finds them in about 3 minutes. As a rough start, many men are comfortable around C3 to C4 (131-262 Hz) and many women around A3 to A4 (220-440 Hz). One octave is 12 steps.
For songs with several parts (soprano, alto, tenor, bass). "Everyone but me" plays the other parts and leaves a gap for yours, like singing in a choir. Learn a part with "All parts" or "Only my part" first. If your own part plays out loud, wear headphones, or the mic hears it and scores it as you. Listen first always plays every part.
How it went
Copies this take, note by note, with a question for a coach. Paste it into any AI chat for tips on what to practice.
Use your own song
Load a MIDI file (.mid), for example one exported from MuseScore or a song-writing app. Each track becomes a part you can pick under "My part" (the top note where a part plays chords).
Or type a melody. Notes are a letter and an octave number (C4 is middle C, 261.6 Hz); each lasts
one beat unless you add a length, like G4:2 for two beats or E4:0.5 for
half a beat. r is a rest (silence). | marks a bar and is optional. Words
go one syllable per note; _ holds a syllable over an extra note. Any AI chat can write
a melody in this format if you paste in this example.
Hymns from churchofjesuschrist.org
Songs from the hymnbooks and the Children's Songbook can be practiced here with every part and verse: add one bookmark, then tap it on the Church site.
On a computer: drag this button to your bookmarks bar: Sing
On a phone: tap , bookmark any page, edit that bookmark, name it Sing, and paste the copied text as its address (URL).
On a song's page, tap the bookmark (on Android Chrome, type "Sing" in the address bar and tap the bookmark) and this app opens with that song; pick your part and verse. Songs without Interactive Sheet Music can't be sent. On any other page of the site, it opens the songbook collector (see the library above).
The hymn goes straight from the Church's page to this app in your browser; this site never stores it. The arrangements are copyright Intellectual Reserve, Inc. and may be copied for incidental, noncommercial Church or home use, so keep shared links to that. If the Church changes its website, the bookmark may stop working until this app is updated.
Timing looks off? Measure the delay
Speakers, headphones, and mics all add a small delay, which can make every note look late. Measure it plays a short melody out loud and listens to it through the mic, the way it listens to you, then sets the adjustment so it scores on time. Take headphones off, turn the volume up, and stay quiet while it runs (about 12 seconds). Measuring again should then read close to 0 ms; readings within about 25 ms of each other are as close as it can tell.
The measurement covers this speaker. Wired headphones use the same timing; Bluetooth headphones add their own delay (often 150-250 ms more), which the mic can't hear, so nudge it with Later. If notes still show late when you're sure you're on the beat, press Later; if early, press Earlier.

New to music? How note names work
Notes are named with letters C D E F G A B, plus "sharps" (C# = a half step above C) for the black piano keys. After B the letters start over, one octave higher. An octave is a doubling of frequency: A3 is 220 Hz, A4 is 440 Hz.
The number is the octave. C4 is "middle C" (261.6 Hz), the middle of a piano. Most adult men speak around 85-155 Hz (roughly E2-D#3), most women around 165-255 Hz (E3-B3).
A semitone (half step) is one piano key, black or white: a frequency ratio of about 1.059. 12 semitones make an octave. A typical pop melody spans 12-18 semitones.
Comfortable range (singers call it tessitura) matters more than extremes. A song in the wrong key for you is the most common reason a song feels "unsingable". Any song can be moved (transposed) to fit your range.
