After all the fuss in my mind over starting without markings on my shamisen, trying to make it difficult for myself.
I ended up marking my shamisen, for the ease of reading tab… and to stop playing notes which shouldnt exist XD
I marked my shamisen with ash, this is a rough version as i just did it… but it works nice and the ash lines stop right where my thumb always is so it wont rub off, I do need help marking more positions though.
