In harmonic analysis and on lead sheets, a C major chord can be notated as C, CM, CΔ, or Cmaj. A major triad is represented by the integer notation {0, 4, 7}. A major triad can also be described by its intervals: the interval between the bottom and middle notes is a major third, and the interval between the middle and top notes is a minor third.
C or Do is the first note of the C major scale, ... middle C has a frequency around 261.63 Hz [1] ... C major; C minor; Root (chord) References
The frequency of a pitch is derived by multiplying (ascending) or dividing (descending) the frequency of the previous pitch by the twelfth root of two (approximately 1.059463). [ 1 ] [ 2 ] For example, to get the frequency one semitone up from A 4 (A ♯ 4 ), multiply 440 Hz by the twelfth root of two.
Pythagorean (tonic) major chord on C Play ⓘ (compare Play ⓘ equal tempered and Play ⓘ just). Comparison of equal-tempered (black) and Pythagorean (green) intervals showing the relationship between frequency ratio and the intervals' values, in cents.
Mozart and Haydn wrote most of their masses in C major. [3] Gounod (in a review of Sibelius' Third Symphony) said that "only God composes in C major". Six of his own masses are written in C. [4] Of Franz Schubert's two symphonies in the key, the first is nicknamed the "Little C major" and the second the "Great C major".
In the key of C major, the first degree of the scale, called the tonic, is the note C itself. A C major chord, the major triad built on the note C (C–E–G), is referred to as the one chord of that key and notated in Roman numerals as I. The same C major chord can be found in other scales: it forms chord III in the key of A minor (A→B→C ...
For the English guitar, the open chord is C major (C–E–G–C–E–G); [26] for the Russian guitar, which has seven strings, it is G major (D–G–B–D–G–B–D). [ 27 ] [ 28 ] When the open strings constitute a minor chord, the open tuning may sometimes be called a cross-note tuning.
Constant-Q transform applied to the waveform of a C major piano chord. The x-axis is frequency, mapped to standard musical pitches, from low (left) to high (right). The y-axis is time, starting from pressing the piano chord at the bottom, and releasing the piano chord at the top, 8 seconds later.
