Guitar Tools
Free tools for playing, not reading: each one does one job on a phone propped on a music stand, with sound, and no sign-up.
Tune & time
- Metronome
Click track 20–300 BPM with time signatures, subdivisions, a speed trainer and strum patterns.
- Guitar tuner
Microphone tuner with a needle in cents, 11 tunings and reference tones for tuning by ear.
- Tap BPM
Tap along to a song: its tempo in BPM, how steady your taps are, then practise it on the metronome.
Analyse a song
- Song key finder
Drop a song or play it to the mic: its key, then the chords to play and the easiest capo.
- BPM finder
The tempo of a song from a file or the mic, half/double time, then a practice click at that tempo.
- Key and BPM accuracy
How often the key and BPM finders are right on labelled real loops, and where they go wrong.
Theory
- Chord progression generator
Key + style → a progression you can hear, with roman numerals, chord shapes and a capo tip.
- Circle of fifths
Tap a key: its chords I to vii° as playable guitar shapes, key signature, relative minor.
- Capo calculator and chord transposer
Song key + the shapes you want → capo fret. Paste chords → transposed, with the best capo for open chords.
- Fretboard notes and scale finder
Every note on the neck, or any scale and arpeggio in any key and tuning, tap a dot to hear it.
- Chord finder (chord namer)
Tap the frets you hold: the chord name, its notes and the other names the same shape goes by.
- Camelot wheel
Tap a Camelot code: the keys that mix with it, its chords and the guitar key page.
Which tool do I need?
- Guitar sounds wrong: tune it first with the guitar tuner.
- You want to play in time, or speed a riff up: the metronome has a speed trainer that starts slow and steps up.
- You want to play along with a recording: the song key finder gives its key and the chords to play; the BPM finder gives its tempo.
- A song is too high or low to sing, or has barre chords: the capo calculator finds a capo fret and easier shapes.
- You hold a shape and want its name: the chord finder.
- You want to know which chords belong together: the circle of fifths, or a key page; to write your own, the chord progression generator.
- You want to solo or learn the neck: the fretboard map shows every note and any scale.
