The C sharp note on a treble clef. C ♯ (C-sharp) is a musical note lying a chromatic semitone above C and a diatonic semitone below D; it is the second semitone of the solfège. C-sharp is thus enharmonic to D ♭. It is the second semitone in the French solfège and is known there as do dièse. In some European notations, it is known as Cis.
In vocal music, the term High C (sometimes called Top C [5]) can refer to either the soprano's C 6 (1046.502 Hz; c ′ ′ ′ in Helmholtz notation) or the tenor's C 5; soprano written as the C two ledger lines above the treble clef, with the tenor voice the space above concert A, sung an octave lower. Sometimes written with “8v” below the ...
Most commonly, [note 2] the sharp symbol (♯) raises a note by a half step, while the flat symbol (♭) lowers a note by a half step. This half step interval is also known as a semitone (which has an equal temperament frequency ratio of 12 √ 2 ≅ 1.0595).
For example, C 4 is one note above B 3, and A 5 is one note above G 5. The octave number is tied to the alphabetic character used to describe the pitch, with the division between note letters ‘B’ and ‘C’, thus: "B 3" and all of its possible variants (B, B ♭, B, B ♯, B) would properly be designated as being in octave "3".
Lowers the pitch of a note to a pitch matching the indicated number in the harmonic series of the root (bottom) of the chord. The diagram shows a specific example, the septimal flat, in the context of a septimal minor third, in which the E ♭ is tuned exactly to a 7:6 frequency ratio with the root (C).
The standard tempered fifth has a frequency ratio of 2 7/12:1 (or about 1.498307077:1), approximately two cents narrower than a justly tuned fifth. Ascending by twelve justly tuned fifths fails to close the circle by an excess of approximately 23.46 cents , roughly a quarter of a semitone , an interval known as the Pythagorean comma .
When one contrasts this with a dissonant interval such as a tritone (not tempered) with a frequency ratio of 7:5 one gets, for example, 700 − 500 = 200 (1st order combination tone) and 500 − 200 = 300 (2nd order). The rest of the combination tones are octaves of 100 Hz so the 7:5 interval actually contains four notes: 100 Hz (and its ...
