Lately I have been trawling YouTube looking for jam sessions to practice my rather ropey backup skills and I am increasingly finding these guys tend not to stick with G, D, C and A. The keys I normally play in and I am having a hard time trying to find the key signature they are in before the song ends. Please forgive me if you have covered this topic already but could you do a lesson sometime on playing in F, E and Bb. Also any tips one can use to find the key by ear quickly when it’s not possible to see the guitar players hands or where a capo is placed.
In this video at 6.40 the mandolin player has her instrument capo’ed at the 3rd fret what key are they in. I don’t ever recall seeing anyone capo a mandolin before seeing this.
