The minor 7th on the guitar
10 semitones · m7 · C → B♭
Its character, in the app's words: freedom; an octave wider (m14), distance: the openness stays unresolved.
The shapes on the neck
- On the same string: 10 frets up.
- On the next string, towards the 1st: 5 frets up; 6 frets up when you cross from the G string to the B string, which are tuned a major 3rd apart instead of a 4th.
- Turned upside down it becomes a major 2nd: 10 + 2 = 12 semitones.
The root is the C on the A string, 3rd fret; the other circles are the same note, B♭, wherever it sits between frets 0 and 12. The 1st string (high e) is at the top, as in the app. The root is filled.
