Pick a chord or a progression and see the two-note shapes that fit it, written out in notation and tab. Use them for fills and harmony lines, or to learn where chords lie on the neck.
Which instruments are there?
Mandolin, violin, mandola, octave mandolin, guitar and banjo.
Can I use a whole progression?
Yes. Enter the chords and see double stops for each one.
What is a double stop?
Two notes played at once on neighboring strings. Fiddle and mandolin players use them for fills, harmony and a fuller sound.
