I would like to learn a few songs that require a drop C tuning.(cgcfad) I put 2 and 2 together so this is what I did. I started off at regular then tuned it to drop d, then tuned the rest down so its regular from the dropped d, then turned the d down again so i guess its a c. I don't have a tuner or piano and can't make it to the store for 2 weeks since I'm only 16. Did I do it right, if not please correct me and explain how I get dropped c tuning starting from dropped d or regular tuning.
