I think so. i thought Its always the same on all instruments ( a half-step each between all notes but ef and bc which dont have anything in between). is that what you mean? i dont really think about in terms of the strings 'cause i play my guitar in a c-sharp and i read tab. Im trying to learn ear training from the guitar grimoire but im not sure about the part with the keys of the scales; like, am i supposed to play a c-sharp scale if thats what my guitars tuned to. know what i mean?
