This note lies a chromatic semitone above A and a diatonic semitone below B, thus being enharmonic to B ♭ (French: si bémol). When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of the A ♯ above middle C is approximately 466.164Hz. [1] See pitch (music) for a discussion of historical ...
The diatonic scale (seven notes)—this includes the major scale and the natural minor; The melodic and harmonic minor scales (seven notes) These scales are used in all of their transpositions. The music of this period introduces modulation, which involves systematic changes from one scale to another. Modulation occurs in relatively ...
The major scale (or Ionian mode) is one of the most commonly used musical scales, especially in Western music. It is one of the diatonic scales . Like many musical scales, it is made up of seven notes : the eighth duplicates the first at double its frequency so that it is called a higher octave of the same note (from Latin "octavus", the eighth).
For orchestral works in A major, the timpani are typically set to A and E a fifth apart, rather than a fourth apart as for most other keys. Hector Berlioz complained about the custom of his day in which timpani tuned to A and E a fifth apart were notated C and G a fourth apart, a custom which survived as late as the music of Franz Berwald .
Relative keys are the most closely related, as they share exactly the same notes. [3] The major key and the minor key also share the same set of chords. In every major key, the triad built on the first degree (note) of the scale is major, the second and third are minor, the fourth and fifth are major, the sixth minor and the seventh is diminished.
Music theory in most European countries and others [note 1] use the solfège naming convention. Fixed do uses the syllables re–mi–fa–sol–la–ti specifically for the C major scale, while movable do labels notes of any major scale with that same order of syllables.
Major and minor third in a major chord: major third 'M' on bottom, minor third 'm' on top. Major and minor may also refer to scales and chords that contain a major third or a minor third, respectively. A major scale is a scale in which the third scale degree (the mediant) is a major third above the tonic note.
