{{subst:prodwarning|Octave scale}} ~~~~


An octave scale is named for the musical note that begins and ends a musical scale. However, though the notes are the same they remain an octave apart, or in other words, the end note is double the frequency of the beginning note. Notes at the letters A, B, C, D, E, F, and G are used to name the musical notes. Using C major, the octave scale would be C, D, E, F, G, A, B, C. The octave number tells us which. As there are eight C notes on the 88-key piano the octave number signifies which C to start with. This article is about music. ... In music, a scale is a set of musical notes that provides material for part or all of a musical work. ... In music, an octave (sometimes abbreviated 8ve or 8va) is the interval between one musical note and another with half or double the frequency. ... Sine waves of various frequencies; the bottom waves have higher frequencies than those above. ... A grand piano, with the lid up. ...


A number (i.e seventh octave) or a note (C5) may be associated when referring to a particular octave scale. The seventh octave is the last octave at the top of a piano. ...


Examples

The first note on the piano is 'A'. Since it is the first note, it is called A0. Note that it vibrates at only 27.5 Hz. The hertz (symbol: Hz) is the SI unit of frequency. ...


The next white note is B0. The black key in between is a half-step and is the sharp of A (A♯0) or the flat of B (B♭0). Figure 1. ... Figure 1. ...


The next white-key notes are C1, D1, E1, F1, and G1 respectively. The black keys in between are the flat of the note after it and the sharp of the note before it.


The next A is the second A, named A1. It vibrates at 55 Hz (double A0). This repeats again, to A2 (110 Hz).


Note

In Scientific pitch notation, octaves are numbered beginning with C and ending with B. In that notation (used in many Wikipedia articles - see Piano key frequencies and Soprano, Alto, Tenor, and Bass, as well as articles on specific instruments), the lowest piano keys play A0, A♯0, and B0. Followed by C1 through A1, B1, and C2, and Middle C is C4. This article or section may be confusing for some readers, and should be edited to be clearer or more simplified. ...

The seventh tone of the major scale is often referred to as the “leading tone” and usually is followed by the tonic or key center, in this case, B to C, when played in a melody or in a series of two chords.
In a C major scale, the perfect fifth is a G, the perfect fourth is an F and a major third is an E. Guitars have six strings of the same approximate length but different pitches due to the different thicknesses and textures of the strings.
If other major scales involving additional sharps or flats are played when a keyboard is tuned to a C major scale with Pathagorean intervals, the music sounds out of tune to trained musicians.
MML: Frequency Module (1961 words)
As the octave is not universal, a more neutral term will be used in MML: noteset, which is not restricted to the 8-note, 2:1 relation set, but is used as a generic term that may as well apply to a 5-note "octave".
There are different conventions for numbering octaves, such as the Helmholz method, (starting about in the middle of the piano keyboard and numbering outwards, thus a dual method) and the method used by music physicists (starting at one end, the lower end, and numbering serially upward).
The A notes on beats 1 and 4 are on octave 3, as specified by the noteset attribute; the second beat on octave 4, the third on octave 2.
