Fretspace is a cool new chord and scale editor for fretted instruments.
Fretspace is a chord and scale editor for guitars and other fretted instruments, such as banjos, mandolins, ukuleles etc. It can be used to create charts of chords and scales in any tuning. Chord and scale shapes are displayed in standard grid boxes, where notes can be added or removed by clicking. There are also chord and scale pickers that calculate and display almost any possible chord and scale shape for the current tuning. Fretspace automatically identifies and labels chords and scales, and automatically calculates fingerings (both are editable). There are options for labelling notes and for displaying root notes in a different colour. A tunings editor allows custom tunings to be created, in addition to the range of standard and alternative tunings that are provided.
Fretspace contains a number of tools for completing or modifying shapes, by inverting them or moving them around the fretboard. Charts can be printed, and shapes can also be copied and pasted into other applications as PDF graphics. The program includes a step-by-step tutorial and detailed reference manual, which are available from the Help menu (and can be printed or viewed on screen).
Fretspace runs on macOS 10.11 (El Capitan) or later. It costs $29 and is available from www.softpress.com. There is a free 7-day trial version.
