Enharmonic Equivalence
In modern musical notation and tuning, an enharmonic equivalent is a note, interval, or key signature that is equivalent to some other note, interval, or key signature but "spelled", or named differently. The enharmonic spelling of a written note, interval, or chord is an alternative way to write that note, interval, or chord. The term is derived from Latin ''enharmonicus'', from Late Latin ''enarmonius'', from Ancient Greek ἐναρμόνιος (''enarmónios''), from ἐν (''en'') and ἁρμονία (''harmonía''). Definition For example, in any twelve-tone equal temperament (the predominant system of musical tuning in Western music), the notes C and D are ''enharmonic'' (or ''enharmonically equivalent'') notes. Namely, they are the same key on a keyboard, and thus they are identical in pitch, although they have different names and different roles in harmony and chord progressions. Arbitrary amounts of accidentals can produce further enharmonic equivalents, such as B (mean ...

Comparison Of Unisons
Comparison or comparing is the act of evaluating two or more things by determining the relevant, comparable characteristics of each thing, and then determining which characteristics of each are Similarity (psychology), similar to the other, which are Difference (philosophy), different, and to what degree. Where characteristics are different, the differences may then be evaluated to determine which thing is best suited for a particular purpose. The description of similarities and differences found between the two things is also called a comparison. Comparison can take many distinct forms, varying by field: To compare things, they must have characteristics that are similar enough in relevant ways to merit comparison. If two things are too different to compare in a useful way, an attempt to compare them is colloquially referred to in English as "comparing apples and oranges." Comparison is widely used in society, in science and in the arts. General usage Comparison is a natural ...

C-sharp Major
C-sharp major (or the key of C-sharp) is a major scale based on C, consisting of the pitches C, D, E, F, G, A, and B. It is enharmonically equivalent to D-flat major. Its key signature has seven sharps. The C-sharp major scale is: : Its relative minor is A-sharp minor (or enharmonically B-flat minor) and its parallel minor is C-sharp minor. A harp tuned to C-sharp major has all its pedals in the bottom position. Because all the strings are then pinched and shortened, this is the least resonant key for the instrument. Compositions Most composers prefer to use the enharmonic equivalent D-flat major since it only contains five flats as opposed to C-sharp major's seven sharps. However, Johann Sebastian Bach chose C-sharp major for Prelude and Fugue No. 3 in both books of ''The Well-Tempered Clavier''. In Hungarian Rhapsody No. 6, Franz Liszt takes the unusual step of changing the key from D-flat major to C-sharp major near the start of the piece, and then back again to B ...

E-flat Minor
E-flat minor is a minor scale based on E, consisting of the pitches E, F, G, A, B, C, and D. Its key signature consists of six flats. Its relative key is G-flat major (or enharmonically F-sharp major) and its parallel key is E-flat major. Its enharmonic equivalent, D-sharp minor, contains the same number of sharps. The E-flat natural minor scale is: : Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The E-flat harmonic minor and melodic minor scales are: : : Music in E-flat minor In the 24 canonic keys, most of the composers preferred E-flat minor, while Johann Sebastian Bach, Sergei Lyapunov, and Manuel Ponce preferred D-sharp minor. In Book 1 of ''The Well-Tempered Clavier'' by Bach, Prelude No. 8 is written in E-flat minor while the following fugue is written in D-sharp minor. In Book 2, both movements are in D-sharp minor. Haydn's Piano Trio No. 41, H. XV.31 in two movements, composed in 1794/95 ...

D-sharp Minor
D-sharp minor is a minor scale based on D, consisting of the pitches D, E, F, G, A, B, and C. Its key signature has six sharps. Its relative major is F-sharp major (or enharmonically G-flat major), and its parallel major is D-sharp major, usually replaced by E-flat major, since D-sharp major's two double-sharps make it impractical to use. Its enharmonic equivalent, E-flat minor, has the same number of flats. The D-sharp natural minor scale is: : Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The D-sharp harmonic minor and melodic minor scales are: : : Music in D-sharp minor D-sharp minor is infrequently used as the principal key of pieces in the Classical era. More common is notation in E-flat minor, which is a relatively manageable key for many brass instruments and woodwinds. In the 24 canonic keys, most of the composers preferred E-flat minor, while Johann Sebastian Bach, Sergei Lyapunov, ...

G-flat Major
G-flat major (or the key of G-flat) is a major scale based on G, consisting of the pitches G, A, B, C, D, E, and F. Its key signature has six flats. Its relative minor is E-flat minor (or enharmonically D-sharp minor), and its parallel minor is G-flat minor, which is usually replaced by F-sharp minor, since G-flat minor's two double-flats make it generally impractical to use. Its direct enharmonic equivalent, F-sharp major, contains the same number of sharps as the G-flat major key does flats. The G-flat major scale is: : Characteristics Like F-sharp major, G-flat major is rarely chosen as the main key for orchestral works. It is more often used as a main key for piano works, such as the impromptus of Chopin and Schubert. It is the predominant key of Maurice Ravel's ''Introduction and Allegro'' for harp, flute, clarinet and string quartet. A striking use of G-flat major can be found in the love duet "Tu l'as dit" that concludes the fourth act of Giacomo Meyerbe ...

F-sharp Major
F-sharp major (or the key of F) is a major scale based on F, consisting of the pitches F, G, A, B, C, D, and E. Its key signature has six sharps. The F-sharp major scale is: : Its relative minor is D-sharp minor (or enharmonically E-flat minor) and its parallel minor is F-sharp minor. Its direct enharmonic, G-flat major, contains the same number of flats in its key signature. Music in F-sharp major F-sharp major is the key of the minuet in Haydn's "Farewell" Symphony, of Beethoven's Piano Sonata No. 24, Op. 78, Verdi's "Va, pensiero" from ''Nabucco'', a part of Franz Liszt's Hungarian Rhapsody No. 2, Mahler's unfinished Tenth Symphony, Korngold's Symphony Op. 40, and Scriabin's Fourth Piano Sonata. The key was the favorite tonality of Olivier Messiaen, who used it repeatedly throughout his work to express his most exciting or transcendent moods, most notably in the ''Turangalîla-Symphonie''. Like G-flat major, F-sharp major is rarely used in orchestral musi ...

G-sharp Minor
G-sharp minor is a minor scale based on G, consisting of the pitches G, A, B, C, D, E, and F. Its key signature has five sharps. Its relative major is B major. Its parallel major, G-sharp major, is usually replaced by its enharmonic equivalent of A-flat major, since G-sharp major has an F in its key signature, making it impractical to use. A-flat minor, its enharmonic, with seven flats, has a similar problem, thus G-sharp minor is optionally used as the parallel minor for A-flat major. (The same enharmonic situation occurs with the keys of D-flat major and C-sharp minor). The G-sharp natural minor scale is: : Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The G-sharp harmonic minor and melodic minor scales are: : : Music in G-sharp minor Despite the key rarely being used in orchestral music other than to modulate, it is not entirely uncommon in keyboard music, as in Piano Sonata No. 2 b ...

Its key signature has seven Flat (music), flats. Its Relative key, relative minor is A-flat minor (or enharmonically G-sharp minor), and its Parallel key, parallel minor is C-flat minor, usually replaced by B minor, since C-flat minor's three Double-flat, double-flats make it impractical to use. The direct enharmonic equivalent of C-flat major is B major, a key signature with five sharps. The C-flat major scale is: C-flat major is the only major or minor key, other than theoretical keys, which has "flat" or "sharp" in its name, but whose tonic note is the enharmonic equivalent of a Natural (music), natural note (a white key on a keyboard instrument). Use in harp music C-flat major is the home key of the harp, with a ...

B Major
B major (or the key of B) is a major scale based on B. The pitches B, C, D, E, F, G, and A are all part of the B major scale. Its key signature has five sharps. Its relative minor is G-sharp minor, its parallel minor is B minor, and its enharmonic equivalent is C-flat major. The B major scale is: Although B major is usually considered a remote key (due to its distance from C major in the circle of fifths and fairly large number of sharps), Frédéric Chopin regarded its scale as the easiest of all to play on the piano, as its black notes fit the natural positions of the fingers well; as a consequence he often assigned it first to beginning piano students, leaving the scale of C major until last because he considered it the hardest of all scales to play completely evenly (because of its complete lack of black notes). Few large-scale works in B major exist: these include Haydn's Symphony No. 46. The aria "La donna è mobile" from Verdi's opera ''Rigoletto'' is in the ke ...

Flat (music)
In music, flat (Italian bemolle for "soft B") means "lower in pitch". Flat is the opposite of sharp, which is a raising of pitch. In musical notation, flat means "lower in pitch by one semitone (half step)", notated using the symbol which is derived from a stylised lowercase 'b'. For instance, the music below has a key signature with three flats (indicating either E major or C minor) and the note, D, has a flat accidental. : Under twelve-tone equal temperament, D for instance is enharmonically equivalent to C, and G is equivalent to F. In any other tuning system, such enharmonic equivalences in general do not exist. To allow extended just intonation, composer Ben Johnston uses a sharp as an accidental to indicate a note is raised 70.6 cents (ratio 25:24), and a flat to indicate a note is lowered 70.6 cents. In intonation, flat can also mean "slightly lower in pitch" (by some unspecified amount). If two simultaneous notes are slightly out-of-tune, the lower-pitched o ...
