I attended an introduction-to-the-banjo workshop yesterday, just out of curiosity. I learned a few interesting things. First, a bluegrass banjo is amazingly heavy, full of brass and wood. Second, it’s tuned to a G chord – if you strum or pick without touching a fret, you get a G chord; if you bar straight across, you get another major chord. But bluegrass banjo players do not strum, they pick in little patterns with three fingers, which is how they get in so darn many notes.
