Getting started

When you create a new document in Frettler, you’ll be asked to select an instrument type, its tuning, and whether you are right- or left-handed.

The instrument/tuning/handedness selections made when the document is created will determine the appearance and layout of all fretboards created within it, and will be re-applied when the document is reloaded. The selections made are summarised in the top left of the document window.

However, you can change any of these choices later using the controls icon to the right of the instrument/tuning title at the top of the document. When you click “Apply”, all fretboards and chord organisers in the document update to match the new settings. For example: start with guitar, standard tuning, right-handed — then switch to a left-handed bass guitar with Drop D tuning, and all panels adjust automatically.

Once you have made that selection and clicked “Apply”, you will be presented with your new but still empty document. Add a fretboard or chord organiser panel using the buttons in the new document welcome page or use the 'Add Panel' button in the top right of the document:

Selecting "Add Chord Organiser" will simply prompt you for the new panels title, whereas "Add Fretboard" will open the fretboard config dialog:

For the “Scale” content type, the available patterns are:

For the “Mode” content type, the available patterns are:

For the “Chord” content type, the available patterns are:

Frettler covers commonly used and practical scales, modes and chords. There are many more we could add - suggestions for additions are welcomed.

Once your fretboard is created, you can others or mix them with chord organiser panels. All the fretboards and chord organisers you create are stored in the current document. Open it tomorrow and they’ll still be there waiting for you.

Create a document for individual instruments or tunings, or for multiple lessons or projects for just one. How you organise your documents is entirely up to you!
