Hello everyone.
I have a problem that I cannot solve.
I received the Harmony exercises from a classmate (N* 10 Basses by Jacopo Napoli)
and looking at his notes, I notice some Modulations.
I know that to modulate to closely related keys it is enough to use ( I5 -> V24 -> I6 or I6 -> V56 -> I5 )
However, I do not understand how he goes from A to modulate to G (second line) and then immediately after to F#.
