E-sharp minor is a theoretical key based on the musical note E ♯, consisting of the pitches E♯, F, G♯, A♯, B♯, C♯ and D♯. Its key signature has eight sharps, requiring one double sharp and six single sharps .
A musical passage notated as flats. The same passage notated as sharps, requiring fewer canceling natural signs. Sets of notes that involve pitch relationships — scales, key signatures, or intervals, [1] for example — can also be referred to as enharmonic (e.g., the keys of C ♯ major and D ♭ major contain identical pitches and are therefore enharmonic).
Four of the scale notes – the tonic (C in the example), subdominant (F), dominant (G), and octave (C′) – are all fixed: They are nearly exactly the same relative pitches in all three categories of ancient Greek scales (enharmonic, chromatic, and diatonic), [4] and in ancient Greek music, the fixed tones relative pitches were very nearly the same as the corresponding notes in the modern ...
Some fixed just intonation scales and systems, such as the diatonic scale above, produce wolf intervals when the approximately equivalent flat note is substituted for a sharp note not available in the scale, or vice versa. The above scale allows a minor tone to occur next to a semitone which produces the awkward ratio 32:27 for D→F, and still ...
Harmonic fragment scales form a rare exception to this issue. In tunings such as 1:1, 9:8, 5:4, 3:2, 7:4, 2:1 , all the pitches are chosen from the harmonic series (divided by powers of 2 to reduce them to the same octave), so all the intervals are related to each other by simple numeric ratios.
A harmonic is any member of the harmonic series, an ideal set of frequencies that are positive integer multiples of a common fundamental frequency. The fundamental is a harmonic because it is one times itself. A harmonic partial is any real partial component of a complex tone that matches (or nearly matches) an ideal harmonic. [3]
A man tuning an upright piano. Piano tuning is the process of adjusting the tension of the strings of an acoustic piano so that the musical intervals between strings are in tune. The meaning of the term 'in tune', in the context of piano tuning, is not simply a particular fixed set of pitches. Fine piano tuning requires an assessment of the ...
the ascending melodic minor scale or jazz minor scale (also known as the Ionian ♭ 3 or Dorian ♯ 7): this form of the scale is also the 5th mode of the acoustic scale. the descending melodic minor scale: this form is identical to the natural minor scale . The ascending and descending forms of the A melodic minor scale are shown below:
