Workshop tool · Free, with limits
The guitarist's toolbox, online
Everything that usually sits next to your music stand, on one page: a metronome, a capo transposer, a reference tuner and printable sheets. Practise in time, play in the right key and get your ideas down on paper, with nothing to install.
Included in the free account with a limit, unlimited with Premium.
The three practice tools
The metronome runs from 40 to 240 BPM. The "Slower" and "Faster" buttons change the tempo by 4 BPM, the slider lets you dial in an exact value, and the Italian tempo marking appears alongside (Largo, Adagio, Andante, Moderato, Allegro, Presto). The first beat of every group of four is accented with a higher click, and four dots light up with the pulse.
The capo transposer answers the question "I've put the capo on, what chord are people hearing?". Choose the fret (from "No capo" to capo 11): the C, G, D, Am, Em and F shapes are listed with the chord that actually sounds. Capo 2: the G shape sounds as A, the C shape as D, the Em shape as F#m.
The reference tuner plays each string's note in standard tuning: E (82.41 Hz), A (110 Hz), D (146.83 Hz), G (196 Hz), B (246.94 Hz), high E (329.63 Hz). Click a string, listen and tune by ear. Think of it as a six-note tuning fork: it does not use your microphone and does not listen to your guitar.
Printable PDF sheets
The second half of the page generates A4 sheets ready to print:
- Blank fretboards: 1 to 8 fretboards per page, 5 to 24 frets, with or without fret numbers, string names and inlays (3, 5, 7…). Perfect for drawing a scale across the whole fretboard.
- Blank chord boxes: a grid of chord diagrams to fill in by hand, with your choice of columns, rows and frets per box.
- My chords (cheat-sheet): tick your chords, add your own (F#m7b5…), give it a title, and the PDF shows the standard diagram for each one.
- Tab paper: six-line staves with bar lines, plus an optional row for chord names.
- Scale sheet: pick a tonic and a scale type; the sheet shows the notes, the degrees, the position on the neck and the diatonic chords to improvise over. A "notate in flats" option writes Bb rather than A#.
A preview lets you check the settings before you download.
Tempo in practice: getting the most from a metronome
A metronome is not just for playing fast: it is for playing evenly. A simple routine for a tricky passage:
- Find the tempo at which you can play the passage cleanly three times in a row, say 60 BPM in eighth notes.
- Click "Faster" once (+4 BPM) and go again.
- At the first slip, drop back 8 BPM and finish the session there.
Use the accented first beat to check that your chord changes land exactly on "1". And write down the tempo you reached: next day, start 8 BPM below it.
Free or Premium: what's included
The toolbox is part of the GuitarHarmony workshop (app.guitar-harmony.com), open with a free account and no card.
- Free: metronome, capo transposer, reference tuner and every type of printable sheet. Printable sheets are unlimited, even on a free account.
- Premium (4.90 € a month or 39 € a year): adds the AI chord-grid generator. Give it a short progression (C, Am, F, G for example), a number of bars from 4 to 32 and optionally a key; it expands the progression into a full song grid, with the degree and diagram for every bar, ready to print.
The AI chord-grid generator comes with Premium: it is not a separately paid feature.
How to use it
- Start the metronome. Set the tempo with "Slower", "Faster" or the slider, then click "Start". "Stop" ends the click.
- Tune up and set your capo. In "Reference tuner", click each string and tune by ear. If you play with a capo, set its fret in "Capo transposer" to read the chords people will hear.
- Pick a sheet. Under "Sheets and grids as PDF", click Blank fretboards, Blank chord boxes, My chords, Tab paper or Scale sheet, then adjust the options.
- Check and download. Open the preview if you like, then generate the A4 PDF. Print it or keep it in your practice folder.
What you can do with it
Bringing a piece up to tempo
The solo is at 120 BPM and you're stuck? Work it at 96 BPM, then add 4 BPM after every clean run. Within a few sessions you reach the target tempo without tensing up.
Singing in the right key
You play in G but the song sits too low for your voice. Capo 2: you keep the G, C, D and Em shapes and the audience hears A, D, E and F#m. The transposer confirms it at a glance.
Preparing a lesson or practice session
Print a scale sheet and a page of blank fretboards: you, or your student, fill in the scale position by position. The chords on the sheet can then go into a chart in the songbook.
Frequently asked questions
Are the metronome and tuner free?
Yes. The metronome, capo transposer and reference tuner are free with a GuitarHarmony account. The metronome, capo transposer, reference notes and every printable sheet are free and unlimited; only the AI chord-grid generator needs Premium.
Does the tuner listen to my guitar through the microphone?
No. It is a reference tuner: it plays the right note for each string (E, A, D, G, B, E) and you tune by ear by comparing. There is no microphone pitch detection.
What tempo range does the metronome cover?
From 40 to 240 BPM, in 4 BPM steps with the buttons or to the exact value with the slider. The first beat of each four-beat bar is accented.
What exactly does the AI chord-grid generator do?
It takes a short progression and expands it over the number of bars you choose (4 to 32): variations, extensions, secondary dominants. Each bar is shown with its degree and diagram, and the sheet prints as a PDF. It is included in Premium.
