Hey Matt, this (mandolin technique: guide fingers post) is awesome. Last month when I went to the jam camp, I attended a session on moveable chords for mandolin that was intended for intermediate players (which I am decidedly not, ha ha). The instructor presented 3 different triad forms with the root of the chord in different positions. She suggested writing out fretboard charts of all the different possibilities in order to pick one of each for the progression. I finally did some of that last night. This morning I was looking at it, scratching my head, wondering how to move from one to another efficiently.

Voila, your post on guide fingers! Just what I needed and just when I needed it! Thanks
