Free music tools

Everything here runs in your browser, free, with no sign-up: a metronome, tuners for guitar, ukulele and bass, a chord finder, a chord transposer, a progression builder and quizzes for reading notes. They all make sound on the first tap.

Practice tools

• MetronomeA steady click from 30 to 260 BPM, with 2/4, 3/4, 4/4 and 6/8, an accented first beat and tap tempo.
• Guitar tunerTune E A D G B E with your microphone, or by ear with a reference tone for each string. Includes drop D and open tunings.
• Ukulele tunerStandard G C E A tuning with re-entrant high G, plus low-G support and a string-to-string method by ear.
• Bass tunerE A D G for four-string bass, with harmonic tips for low strings and notes on the 5-string low B.
• Chord finderTap notes on a keyboard and get the chord name, including inversions and slash chords.
• Chord transposerPaste a chord chart and move it to any key, with sharps or flats, plus a capo chart for guitar shapes.
• Progression builderPick a progression, key and tempo, hear it loop on piano or guitar, and share it with one link.
• Circle of fifthsTap any key on the circle to hear its main chords and see its key signature and relative key.

Note-reading trainers

Each trainer shows a note (on a staff, a keyboard or a fretboard), you pick the letter, and you hear the note whether you were right or not. That links the name, the position and the sound, which is what makes reading stick.

• Treble clef notesLines, spaces and ledger lines, with a tap-to-hear staff and a name-the-note quiz.
• Bass clef notesThe left-hand staff, where middle C sits, and a quiz from E2 to C4.
• Piano notesA full keyboard with every key named and playable, and a find-the-key quiz.
• Guitar fretboard notesEvery note to the 12th fret, octave shapes, and a fretboard quiz.
• Bass fretboard notesThe four-string bass neck, root-fifth-octave shapes, and a quiz.
• Ukulele fretboard notesGCEA tuning with re-entrant G explained, landmark frets, and a quiz.
• How to read musicNote values and rests you can hear, time and key signatures, and a two-bar example that plays.

A simple routine using these tools

You don't need every tool every day. A short routine that covers the basics works better than a long one you skip.

1. Tune (1 minute). Use the guitar, ukulele or bass tuner. Playing out of tune makes even correct chords sound wrong, and it trains your ear badly.
2. Read (2 minutes). One round of a note trainer. Treble clef for most instruments, both clefs for piano, the fretboard quiz for guitar, bass or ukulele.
3. Change chords in time (5 minutes). Open the progression builder at a slow tempo and switch chords on the beat. When it's easy, speed up a little.
4. Play something (the rest). Look up any chord you don't know in the chord library, move a chart into a comfortable key with the transposer, and keep time with the metronome.

How the tools are built

All the tools share the same sound engine and music theory code as the rest of Hear the Chord, so a chord drawn anywhere on the site is the chord you hear, and the note names in the quizzes match the diagrams on the chord and scale pages. The sounds are synthesized in your browser, which is why there is nothing to download and why they respond the moment you tap. The tuners listen through your microphone only while you have them switched on, and the audio never leaves your device.

If you're just starting, pair these with the first guitar chords, first piano chords or first ukulele chords, and the music theory guide when you want to know why things work.
