Some weeks ago, Rob MacKillop launched a website devoted to the Russian 7 string guitar and its repertoire, where he shares his own learning process of this similar, yet different instrument, and inviting everybody to jump along. The website, if you didn't visited yet is sarenkoandco.com
I decided to put to side my resistance to learn to read in a different tuning, re-stringed my guitar, and it has been a fun process.
From the patriarch of the Russian Guitar, Andrei Sychra, a simple set of variations on a folk song "Как иэ-эа леса, лесочка" (As from beyond a forest). The score is available on https://sarenkoandco.com/on-the-essence ... ng-guitar/
