I have a question on some of the dynamics markings in Carcassi's Etudes (Op. 60). In No. 1, there are two markings I am unfamiliar with - pf and rf. Some have suggested that pf is the same as p/f but this doesn't seem correct as there is no repeat. Other have suggested that rf denotes a rest stroke? Does anyone have any information on these markings?
Thanks for you help!
