guitar chords and tabs is an app to visualize the layout of scales and arpeggios on a variety of fretboards. It aims to help players get a better grasp on scales, and ultimately to become a flexible learning and practicing tool for musicians interested in music theory and improvisation.
Choose between a variety of instruments (from ukulele to 11-string guitar) and tunings, set the length of the fretboard, and switch between left- and right-handed fretting.
The main feature that distinguishes guitar chords and tabs from other similar apps is the ability to display several sequences of notes on the same fretboard. You can overlap scales and arpeggios, display their intersections and select specific positions on the neck.

The UI has been designed to be simple and intuitive, and to work on both desktop and mobile devices. Dark mode included!
