The Notes of Music:
Western music has 12 notes of which 7 are “natural” (“”) notes and 5 are “sharps” or “flats”. These natural ones are named from A through G. Sharps are written with the “#” symbol after the names of the notes less shrill than it where as flats are written with the “b” symbol after the name of the note shriller than it. All the notes barring B and E have sharps. A sharp note is shriller than its natural note but less shrill than the natural note after it. Sharps and flats indicate the same note and are merely two names of the same thing.
The notes are used in cyclical order and each octave below and above are noted by the same sets of notes repeating themselves. Thus “A” of a higher octave is of double the frequency of the present and half of that of the lower though they are all A’s. That is not a problem for the staff notation as these “repeating” note names that are an octave or two apart are written on the staff at different place (see below).
Thus the 12 these notes in order are as follows:
A A# B C C# D D# E F F# G G#
A Ab G Gb F E Eb D Db C B Bb
The series above with the sharps is called the Ascending Chromatic Scale, and the ones with the flats are called the Descending Chromatic Scale.
Here one must remember that,
A# = Bb, C# = Db, D# = Eb, F# = Gb, G# = Ab
Any note that is not accompanied with a # or b is a natural, so,
A = A , B = B, ...... G = G
The sharp, flat and natural signs are very fundamental to staff notation.
German connection: One more point is better mentioned here, that in German notations, B is written as H, making the series A H C D E F G A H...This is important as some files available on the net have this “H” in them, especially those in chords.
