Frequently asked questions
How do I read the chord diagram?
The vertical lines are the strings, from the 6th (low E) on the left to the 1st (high E) on the right, and the horizontal lines are the frets. The dots show where to press, O means an open string and X a string that should not be played.
Where do the positions come from?
The tool calculates them itself: it looks for fret combinations, within a span of up to 4 frets, that play all the notes of the chord with the root in the bass, and sorts the easiest first.
What is the difference between C7 and Cmaj7?
Both have the notes of C major (C, E, G) plus a seventh. In C7 it is the minor seventh (B flat), which gives the dominant, tense sound. In Cmaj7 it is the major seventh (B), with a softer sound, widely used in jazz and bossa nova.
