For example, in twelve-tone equal temperament (the modern system of musical tuning in the West), the notes C♯ and D♭ are enharmonically equivalent - that is, they are the same key on a keyboard - and thus are identical in pitch, although they have different names and diatonic function, or role in harmony and chord progressions.
In a given diatonic scale, an individual note name may only occur once. In the key of F for example, the major scale is: 'F, G, A, B♭, C, D, E, (F)'. Thus, the 'B' is called 'B♭' rather than 'A♯' as we already have a note named 'A' in the scale. The scale of F♯ major is: 'F♯, G♯, A♯, B, C♯, D♯, E♯, (F♯)'; thus we use the term 'A♯' instead of 'B♭' as we need the name 'B' to represent the 'B' note in the scale, and 'E♯' instead of 'F' as we need the name 'F' to represent the 'F♯' note in the scale. ......
I have been reading about music theory, and I don't have even a master, who gimme words from a teacher, learn how it is, translate the technical words in some easier to understand.
Thinking that I am a fool for the type of my stupid comments, because I am new to the subject of music theory,
and sometimes these comments can be irritating and do not want to be annoying with questions or comments about any connection with any esplicacion points of music theory .. I appreciate sharing your knowledge... see ya then! |

C# and D# are not enharmonically equivalent... Ever.
C# and DFlat are.. I don't know if it's just how the flat and sharp symbols came thru in your post, but as it is.. this information is very wrong.
Also, not to be rude, but if I couldn't correctly read or speak French I would not try and learn from French text.. |

C# and D# are definitely not the same. If you mean C# & Db, then the different naming convention is to keep all the accidentals in a scale all # or b. Also, to make sure when you write the scale on manuscript paper a note is written on every line and space (that's why some scales contain accidental double bb or ##)
If you want to go deeper. This may have something to do with the fact that the 12 tone scale is a compromise to bypass the Pythagorean comma. (Tonic frequency x 2/3's is the only perfect harmonic, further divisions to create new notes result in decimal points)
We've had to get used to an imperfect diatonic system that doesn't require retuning when the tonic changes.
C# and Db should be different depending on the scale, but actually aren't due to western 12 tone compromise and are now seen as the same tone and frequency. |
