Is that F Clef between the beam of those two notes in the 3rd bar proper notation? if so, what does it mean? I'm guessing it's the same as the G Clef that precedes it, so that the next note would be C instead of an A, am I right?
This question is not really the same, as my question as a whole was: is there a difference with that clef under the beam and the other clef changes?
