As I understood from the tutorial, the short code
\key d \major cis4 d e fis
Is this the only way to type it, or is there a natural way to get the same output by absorbing the
sharps in the key, i.e. since D major already signals that
f really mean
f-sharp, respectively, I'd like to know if it's possible to get the same pdf and midi by typing
\key d \major c4 d e f
P.S. Sorry if this is somewhere else in the tutorial, I'm just trying to produce my hello world in Lilypond.
