Here I've compiled the simplest inversions of most of the chords for mandolin and Tenor banjo. The shapes also relate to the fiddle. There are four or five inversions for most chords on the Mandolin, these are the one's I use.
The first artist is Vicki Shell, of Johnson City, TN. Vicki is a musician and builds mandolins out of canteen gourds. I have seen some beautiful gourd banjos and guitars, but this is the first mandolin I've seen.
