Navigating Options On The Fingerboard

This is a little one-off lesson I've been thinking about doing for a long time. Stringed instruments are weird, and guitar is no exception. One weird thing about stringed instruments is that many duplicate or "unison" notes can be found all over the fingerboard. In other words, you can play the exact same chord or scale or riff in multiple places. These tones are not different octaves, they are the same frequency.

I've attached two PDFs, one is a detailed, high color, printer-unfriendly recap of this lesson with a few examples. The other PDF is unison-finder scratch paper with subtle colors that are (hopefully) more printer friendly for those of you who want to print.

Here are a few questions for the community to ponder and discuss in the comments below or in the community forum: If your fingers are already comfortable, would there be any musical reason to play the same phrase or chord on different strings? Have you found that you prefer voicings on any particular set of strings, like strings 2, 3, & 4 or 4, 5, & 6? Is there a specific situation where you've used this unison note finder method to make something easier or better sounding?
