B flat note, C note, D note, E flat note, F note, G note, A note, B flat note.
C flat is located to the left of C. It is enharmonic with the note B.
C sharp, D flat (C#, Db)
C flat is the same as B natural.
The Western musical system has 12 individual semitones which divide the octave (an octave being the point at which the musical system repeats itself). However, the Western musical system only uses seven letter names to represent notes (A, B, C, D, E, F, G). The remainder of the 5 notes are given names which identify their relationship between the note and the closest named note. On the piano keyboard, the "named" notes are the white notes. The black notes take their names from the closest white note. The purpose of Sharps/flats is to raise/lower a note by a half-step. The word "sharp" indicates a note which is half-step higher (to the right). C-sharp (also, C#) is the black note to the right of the note named "C". D# is the black note to the right of the note named "D". The word "flat" indicates a note which is half-step lower (to the left). E-flat (also, Eb) is the black note to the left of the note named "E". Db is the black note to the left of the note named "D". This naming system creates two strange issues. First, each black note takes on two different names. The black note to the right of C is also to the left of D. This means that this note is known as both C# and Db. Musicians say that C# is the ENHARMONIC EQUIVALENT to Db, and understand that both names refer to the same location on the keyboard. Second, because not every white note has a black note beside it, certain white notes can also be known by "sharp" or "flat" terminology. For example, there is no black note in between B and C, and no black note in between E and F. This means that C is to the right of B, and is therefore also B#. B is to the left of C, and is therefore also Cb. By the same logic, F is E# and E is Fb.
Any note which is "flat" is always one half step lower that the specific white note you're talking about, B-flat is one half step lower than B, so that is the black key just to the left of B. Thus A-flat is the black key just to the left of A, G-flat is the black key just to the left of G, E-flat is the black key just to the left of E and D-flat is the black key just to the left of D. For C-flat and F-flat, there are no black keys between B and C & E and F so therefore C-flat would have to be B and F-flat would have to be E. Any note which is "sharp" is always one half step to the right of the specific white note your labelling. Thus F-sharp is the black key directly to the right of F, G-sharp is the black key to the right of G, A-sharp is the black key to the very right of A. C-sharp is the black key to the right of C and D-sharp is the black key to the very right of D. For E-sharp and B-sharp, since there is no black key between the notes I mentioned above, E-sharp would sound the same as F and B-sharp would be the same as C. Most of the time when we're talking about "sharps" and "flats", we're referring to a black key.
white = natural note = c, d, e, f, g, a, b = do, re, mi, fa, so, la, ti, do black = sharp or flat note = c# (=d flat), d# (=e flat), [there's no e#] f# (=g flat), g# (=a flat), a# (=b flat), [there's no b# either] It's generally accepted that the white keys are used more often than the black.
b means the flat version of the note, one semi-tone below C. Between notes B and C on any clef there is only one semi-tone, so there is no C flat note. The C flat note is actually B.
The enharmonic of a note is another note that sounds the same, so the enharmonic of d flat would be c sharp.
Do you mean the note? An enharmonic of D sharp is E flat.
B, or Ax.
A sharp raises a note by a half-step. A flat lowers a note by a half-step. Any one key on the piano - both white and black - can be referred to as a sharp or a flat. For example: C-natural - a white key - can also be called B-sharp or D-double-flat. Or, for another example: G# - a black key - can also be called A-flat. The exact symbol used for a note (i.e. a flat or a sharp) is determined by the key signature and the specific harmonics within the music.
