An octave is always 8 white keys and 5 black keys.
30
Most have 88 keys (36 black keys and 52 white keys)
In an Octave or Perfect Eighth, there are 12 ( 13 if you count the eighth). For scales that begin on white keys, there are always 8 white keys and 5 black keys in a single full octave. For scales that begin on black keys, there are always 6 black keys and 7 white keys in a single full octave.
In an octave there are eight white notes, C D E F G A B C. For the black notes there are 6, if you are going from C sharp to C sharp again. Hope this helps. Five black keys per octave is probably a better way to think about it.
8.
Two each have 6 keys in between them
There are 7 octaves on a standard grand piano (plus a minor third, or one additional "black key"). If each octave has 5 accidentals (or black keys) then 7 octaves would have 35 black keys, plus the additional B Flat at the bottom of the piano.....so: A 72 key piano has 36 black keys.
try 5x8. there are 8 keys in one octave, and you want to know 5 0ctaves. multiply
No. The piano does have eighty-eight keys, but including the black keys (sharps or flats), it takes twelve keys to make an entire octave, so it's closer to eight octaves.
36 black keys are on a piano.
