A-sharp Major
In music theory, a theoretical key is a key whose key signature would have at least one double-flat () or double-sharp (). Double-flats and double-sharps are often used as accidentals, but placing them in the key signature (in music that uses equal temperament) makes the music generally impractical to read. Enharmonic equivalence For example, the key of G-sharp major is a key of this type, because its corresponding key signature has an F (on its leading-tone), giving it eight sharps. An equal-tempered scale of G-sharp major scale consists of the same pitches as the A-flat major scale, so that the two scales sound exactly the same; such key pairs are said to be enharmonically equivalent. Consequently, the theoretical key of G-sharp major is usually notated as A-flat major which has four flats. Even when enharmonic equivalence is not resorted to, it is more common to use either no key signature or one with single-sharps and to provide accidentals as needed for the Fs, than to ...

Music Theory
Music theory is the study of the practices and possibilities of music. ''The Oxford Companion to Music'' describes three interrelated uses of the term "music theory". The first is the "rudiments", that are needed to understand music notation (key signatures, time signatures, and rhythmic notation); the second is learning scholars' views on music from antiquity to the present; the third is a sub-topic of musicology that "seeks to define processes and general principles in music". The musicological approach to theory differs from music analysis "in that it takes as its starting-point not the individual work or performance but the fundamental materials from which it is built." Music theory is frequently concerned with describing how musicians and composers make music, including tuning systems and composition methods among other topics. Because of the ever-expanding conception of what constitutes music, a more inclusive definition could be the consideration of any sonic phenomena, ...

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 ...

B-flat Minor
B-flat minor is a minor scale based on B, consisting of the pitches B, C, D, E, F, G, and A. Its key signature has five flats. Its relative major is D-flat major and its parallel major is B-flat major. Its enharmonic equivalent, A-sharp minor, which would contain seven sharps, is not normally used. The B-flat natural minor scale is: : Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The B-flat harmonic minor and melodic minor scales are: : : Characteristics B-flat minor is traditionally a 'dark' key. The old valveless horn was barely capable of playing in B-flat minor: the only example found in 18th-century music is a modulation that occurs in the first minuet of Franz Krommer's Concertino in D major, Op. 80.

D-flat Major
D-flat major (or the key of D-flat) is a major scale based on D, consisting of the pitches D, E, F, G, A, B and C. Its key signature has five flats. It is enharmonically equivalent to C-sharp major. The D-flat major scale is: : Its relative minor is B-flat minor. Its parallel minor, D-flat minor, is usually replaced by C-sharp minor, since D-flat minor features a B ( B-double-flat) in its key signature making it impractical to use. C-sharp major, the enharmonic equivalent to D-flat major, has a similar problem as it contains seven sharps. Therefore, D-flat major is often used as the parallel major for C-sharp minor. (The same enharmonic situation occurs with the keys of A-flat major and G-sharp minor). For example, in his Prelude No. 15 in D-flat major ("Raindrop"), Frédéric Chopin switches from D-flat major to C-sharp minor for the middle section in the parallel minor, while in his ''Fantaisie-Impromptu'' and Scherzo No. 3, primarily in C-sharp minor, he switche ...

A-sharp Minor
A-sharp minor is a minor musical scale based on A, consisting of the pitches A, B, C, D, E, F, and G. Its key signature has seven sharps, while the direct enharmonic equivalent, B-flat minor, has five flats. Its relative major is C-sharp major (or enharmonically D-flat major), and its parallel major is A-sharp major, usually replaced by B-flat major, since A-sharp major's three double-sharps make it impractical to use. A-sharp minor is likely the least used minor key in music as it is not generally considered a practical key for composition. The enharmonic equivalent B-flat minor, which only contains five flats as opposed to A-sharp minor's seven sharps, is preferable to use. The A-sharp natural minor scale is: : Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The A-sharp harmonic minor and melodic minor scales are: : : In Christian Heinrich Rinck's 30 Preludes and Exercises in all major and ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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''.

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 ...
