This is a piano sheet. The second line is in bass clef. The blue one and the green one are same. How should I play this two?

Should I pick up my left hand and play the blue one?

    O.k., so what's the key signature?

  • What do you mean "the blue one and the green one are [the] same"?

  • But lets say its in c major key - if the note in the trebble is Fb and in the bass cleff is E how would you play it? I also seen scores like that with same notes it is not clear how would you play similar note that apear in both cleffs simultanesly

    @LoveIsHere This "lets say" is quite pointless here. I would give an answer to that case (as this scenario is very common in organ music actually), but I don't want to answer so unclear question, and I doubt that E and Fb appear simultaneously.

    @LoveIsHere - the way I see it is that when a question is asked, as much relevant information as is needed should be provided by the poser. Here, it's insufficient.

Without the key signature, it's not a total certainly, but it appears that the treble clef note is Fb, which is in fact the white key to the left of F,a.k.a. 'E', while the bass clef note is either E or Eb. If it's Eb, then it's a different note, and will be held on. If it's E, then I can't think why the r.h. note would need to be written as anything but E, certainly not Fb. It rather depends on the key signature though...

  • The signature almost certainly has flats, since otherwise it wouldn't make sense to notate both a B and a C flat for the right hand. Commented Mar 2, 2018 at 7:15

I also notice the C-flat later on in the bar, which is enharmonically equivalent to a B natural. Since it is preceded immediately by a B, it is almost certain that there is at least a B-flat in the key signature. But as the response above says, it would be awkward if the E in the left hand was not a flat, because it would otherwise not be technically playable. So I am pretty certain that there should be an E-flat in the key signature as well. Also accounting for the double bar which indicates this bar is the beginning of a section or theme, I think the key would be either B-flat major or E-flat major, but it could also be a modulation to D-flat minor (which has a F-flat), but as before, I cannot guarantee a firm response until you tell or show us what the key signature is.


I suspect it's in 5 flats. Then it all makes perfect sense.

  • Because the last four notes in RH spell a natural E-flat minor scale - which has six flats including C-flat, but not F-flat; the F-flat there is merely an enharmonic respelling of E-natural to avoid clashing with the E-flat in LH.
