Today I decided to look for "At Seenteen" (1975) by Janis Ian. She is an award winning songwritter, and desevedly so to say the very least!
I found it and started messing around trying to play it. What a surprize! she is tuned to Leonards C (drop C--basically taropatch with a C bass). Wow, no wonder I could never figure these songs out when I was younger!
Great song! For sure it is worth listening to again. Maybe you can get some new chords from it. Check out the beautiful guitar.
