In 1st measure - first chord - it's said that it is C#min (i) but there are C-C#-G. I thought it should be C#-E-G# why is it C#min (i) if there are C-C#-G??
In 3st measure - first chord - it's said that it is A (VI) but there are A-A-A. I thought it should be A-C#-E why is it A (VI) if there are A-A-A??
In some measures (i.e. 4,12,13,25,48 etc.) there are 3 or 4 chords in one measure. I thought, in general, chords could change only on strong beats(except for syncopation). Does that mean there's a syncopation in there or what?
