How to Use

Start on the Chords tab: pick a root note, pick a chord type, and the voicing appears on the fretboard. Use the numbered buttons to switch between positions — every chord has several shapes up and down the neck. Hit the play button to strum it. Try selecting A and Minor — you'll see the open Am shape at the nut plus every other spot those notes show up.

Flip to the Scales tab, pick a root and a scale type. Root notes show up as filled dots; the rest are outlined. Select G and Major to see the classic G major scale laid out across all 15 frets — great for finding new positions to practice.

Click or tap any dot on the fretboard to hear that note. Works on mobile too — just scroll sideways to see all the frets.
