Guitar Calculator

Guitar Calculator is a simple tool for beginner guitar players to show the notes and chords that go together for a given key and scale. It allows you to select a key, scale, hand, and tuning to see what notes on the fret board to play and how those notes are used to build chords.

Notes within the selected key and scale are highlighted on the fret board, which is arranged depending on what hand you select. The scale notes are shaded by their frequency to show you which matching notes are the same, higher or lower. A chord table identifies the degree and notes that make up each chord.
